Medical marijuana shows promise for ailing companion animals.
February 10 2016
A Bulldog who spent two years either lying down or throwing up plays like a puppy thanks to a daily dose of medical marijuana. A Boxer’s skin cancer begins to disappear following topical applications of cannabis oil. A 12-year-old Lab mix diagnosed with liver and lung cancer regains his appetite and becomes more himself after his owner gives him a cannabis tincture purchased from a licensed medical marijuana dispensary.
These stories offer hope to those of us who live with aging and/or infirm dogs, hope that we can improve the quality of their lives and perhaps even extend them.
Even more hopeful is the fact that these aren’t isolated incidents, but rather, three in an ever-increasing narrative of companion animals and cannabis- assisted healing. Yet, veterinarians played little to no official role in them. Why? Because Cannabis sativa (aka marijuana, grass, pot, hash, ganja, et al.)— a plant cultivated for literally thousands of years for its seeds, fibers and medicinal value—is a federally designated Schedule 1 controlled substance, a “drug with no currently accepted medical use and a high potential for abuse.”
So, even if vets believe that medical marijuana could or would relieve a dog’s pain, nausea or seizures, their hands are tied, including in the 23 states and the District of Columbia where cannabis is legal for human medical use. Physicians in those states are exempt from prosecution, but veterinarians don’t have the same protection. Prescribing, or even recommending, cannabis for medicinal use exposes them to the loss of their license to practice.
It’s a difficult place for a vet to find him- or herself: to have a remedy that has been shown to have very real benefits but not be able to use it, or even mention it, without career-ending consequences. Nonetheless, some have put their livelihoods at risk by challenging that prohibition, usually for the same reasons given by the late Doug Kramer, DVM, of Chatsworth, Calif., in a 2013 interview with Julia Szabo: compassion, and to prevent owners from accidentally overdosing their animals in well-intentioned efforts to relieve their pain.
And that’s part of the veterinary quandary. Medical marijuana has been described as the new “dot.com” boom, fueled by a growing body of research that seems to be validating cannabis’s beneficial effects for people. When people are helped by a particular treatment, they tend to want to share it with their ailing companion animals.
With medical marijuana, they’re doing this in increasing numbers, acting on the belief that if it works for them, it can also work for their dog or cat … or horse, for that matter. In doing so, they’re not necessarily curing incurable conditions but rather, are helping their animals enjoy daily life with better appetite and less pain until age or disease ultimately catches up.The Backstory
The plant world has given us some of our oldest and most trusted—and, it’s true, sometimes abused—remedies. Pain relievers like codeine and morphine (poppy); colchicine, an antitumor drug (autumn crocus); the cardiac drug digitalin (purple foxglove); antimalarial quinine (quinine tree); and salicin, the chemical precursor to aspirin (white willow). The list is long.
When that plant has a cultural backstory like marijuana’s, however— “demon weed” in the ’50s, counterculture toke of choice in the ’60s, DEA Schedule 1 drug in the ’70s and onward —empirical evidence is harder to come by. Many barriers are placed in the path of those who want to find answers to questions about marijuana’s potential healing powers. Consequently, there’s a scarcity of rigorous research on the topic, particularly for veterinary application.
Determining whether or not to bring medical marijuana into general and legal use nationwide for humans and animals alike—and how to do it in a way that maximizes its benefits and minimizes its risks—requires this research. Stories, no matter how compelling and promising, are not science, and anecdotal evidence isn’t evidence in the scientific sense. Rather, hypotheses need to be tested in randomized, placebo-controlled studies, the results analyzed and conclusions drawn. The results are then retested and found to be replicable (or not) by others.
Until relatively recently, claims for cannabis’s medicinal values haven’t been supported in this way. As Hampton Sides notes in “High Science,” the June 2015 National Geographic cover story, “for nearly 70 years, the plant went into hiding, and medical research largely stopped … In America, most people expanding knowledge about cannabis were, by definition, criminals.”The Science
Now for the more technical aspects of the topic, greatly simplified and synthesized.
The first published research related to cannabis and companion animals appeared in 1899 in the British Medical Journal. Written by English physician and pharmacologist Walter E. Dixon, the article included Dixon’s observations on dogs’ response to cannabis. However, it would be almost 100 years before we understood where the response originated: in the endocannabinoid system (ECS).
All vertebrates, from sea squirts to humans, have an endocannabinoid system, which scientists estimate evolved more than 600 million years ago. This ancient system, unknown until the late 20th century, is named for the botanical that most dramatically affects it, Cannabis sativa. Cannabinoids are the ECS’s messengers. The system’s purpose is to maintain internal balance— to “Relax, Eat, Sleep, Forget and Protect.”
Marijuana, a complex botanical with more than 400 known natural compounds, contains at least 64 phytocannabinoids (plant-based cannabinoids). The two produced in greatest abundance are cannabidiol (CBD) and tetrahydrocannabinol (THC).
How do they work? According to the National Cancer Society, cannabinoids “activate specific receptors found throughout the body to produce pharmacologic effects, particularly in the central nervous system and the immune system.” The effects depend on the receptors to which they bind.
Robert J. Silver, DVM and veterinary herbalist of Boulder, Colo., provides another way to look at it. “Receptors are like locks, and cannabinoids are like keys. They fit together perfectly. Once the cannabinoid connects to the receptor and ‘turns that lock,’ a series of actions in the cell membrane occur; these actions are responsible for some of the cannabinoid’s effects.”
In his forthcoming book, Medical Marijuana and Your Pet, Dr. Silver notes that the ECS is unique in the world of neurotransmitters. Instead of releasing signals across a synapse (gap) in a forward direction, “the body’s naturally occurring endocannabinoids travel backward from the post- to the presynaptic nerve cell, inhibiting its ability to fire a signal. This is one way the ECS helps modulate and influence the nervous system.”
Research has revealed two distinct cannabinoid receptors, CB1 and CB2. As in other vertebrates, canine CB1 receptors are primarily found in the brain, but also appear in dogs’ salivary glands and hair follicles, while CB2 receptors are localized in canine skin, immune system, peripheral nervous system and some organs, such as the liver and kidneys.
Of the currently known cannabinoids, only one—THC—provokes a “mind-bending” response. CBD, on the other hand, has several well-documented biological effects, including antianxiety, anticonvulsive, antinausea, anti-inf lammatory and antitumor properties.
Terpenoids, components that give plants their distinctive odors, also play a role, helping cannabis cross the bloodbrain barrier and work synergistically. Ethan B. Russo, MD, associated with GW Pharmaceuticals in the UK, calls this the “entourage effect.” In an article in the British Journal of Pharmacology, Russo notes that terpenoids may make a meaningful contribution to cannabisbased medicinal extracts “with respect to treatment of pain, inf lammation, depression, anxiety, addiction, epilepsy, cancer, fungal and bacterial infections (including methicillin-resistant Staphylococcus aureus [MRSA]).” The entourage effect also suggests that in general, the whole plant, with all of its phytocannabinoids, is likely to be most effective for medicinal purposes.
Those who choose to treat their companion animals with medical marijuana generally give it to them in one of two ways: as an oil or as an edible —a food item made with marijuana or infused with its oil. While edibles intended for human consumption usually contain THC, those for dogs and cats more commonly use CBD from industrial hemp, strains of cannabis cultivated for non-drug use, which has almost no THC.
In 1996, California became the first state in the nation to legalize medical marijuana. It now has the largest legal medical marijuana market in the U.S. —not to mention an almost clichéd historical relationship with the herb— so it’s no surprise that many who are pushing the boundaries of its use with companion animals are based there.
Constance Finley, founder of Constance Pure Botanical Extracts (a Northern California legal medical cannabis collective) became involved in cannabis use with dogs when her 10-year-old service dog was diagnosed with hemangiosarcoma and given six weeks to six months to live.
Finley had been using cannabis oil herself to treat the effects of a debilitating autoimmune disease that began when she was in her mid-40s. The prescription medication she took almost killed her, she says, an experience that inspired her to set aside her long-held bias against marijuana and give it a try. The oil provided both pain- and symptom relief, and Finley went on to study cannabis cultivation and the complicated laws around its use. She eventually developed proprietary blends of highly concentrated oils from multiple strains of cannabis, extracted with organic, food-grade solvents.
So, when her much-loved dog was struggling with cancer, she says she dithered, then began giving the dog small amounts of cannabis oil, wiping it on her gums. Within days, the dog started to move around normally and eat; after three weeks of treatment with the oil, her vet could find no signs of the cancer. Unfortunately, she didn’t completely understand how cannabis worked; she figured her dog was cured and stopped using the oil. Within six months, the cancer was back, and ultimately it claimed her dog’s life.
However, the experience made her a believer in its value for companion animals. While to date, there’s been no dog-specific research on its medical use, Finley is confident that cannabis oil has a place in the veterinary toolbox.
In her work with human clients, Finley says she has yet to see a conflict between conventional medications and cannabis, although anyone using it with dogs needs to be aware of the dog’s entire situation. It’s critically important, she says, that the dose be correctly titrated so the dog’s system isn’t hit with too much THC too quickly. She also notes that the effectiveness of an individual dog’s endocannabinoid system, not the dog’s weight, determines the dose. To establish the correct dose, it’s necessary to work with and observe the dog.
A dosage protocol for dogs is one of the areas in need of study and standardization. In the mid-1970s, researchers found that dogs have a high concentration of CB1 endocannabinoid receptors in their hindbrain and medulla as well as other areas of the brain. This suggests that, in terms of compounds that include THC, dogs require less to get the desired effect. (One of the diagnostic signs of THC overdose is something called “static ataxia,” first described in the 19th century and unique to dogs. Dogs in this condition rock rigidly back and forth and drool, their muscles tense up, and their pupils dilate.) According to Dr. Silver, when it comes to dogs and medical marijuana, “The ratio of brain weight—and by extension, receptors— to body weight is not linear.”
Finley also observes that there are at least two myths about medical marijuana that need to be dispelled. First, that CBD is good and THC is bad; each has its uses, but for cancer in particular, she says, THC is the workhorse. Second, that hemp and cannabis are the same; they are different varieties or sub-species, and while CBD can be refined from hemp, she feels that cannabis provides oil that is more easily used by the body.
In Oakland, Calif., Auntie Dolores has been making cannabis-infused edibles for California’s medical marijuana users since 2008. It recently launched Treatibles, a new, locally manufactured product for dogs and cats. The active ingredients are CBD, CBN (cannabinol) and CBG (cannabigerol) distilled from European industrial hemp, which, founder and CEO Julianna Carella notes, is “non-toxic, 100 percent safe and non-psychoactive. Even dogs who do not have health problems can use the product as a preventive measure.”
Each bag of Treatibles, about 40 pieces, contains 54.6 mg of CBD; each t reat contains about 1 mg. Carella says that the company guarantees 40 mg per bag, but often the consumer gets a bit more. “We feel that all products purporting the health benefits of CBD should have at least enough of the material in the product to warrant the price, as well as to provide a medicinal dose. Even so, dogs are more sensitive to cannabinoids and generally need less than humans.”
Carella says that she was inspired to develop edibles for companion animals by cannabinoid science and research into the endocannabinoid system as it relates to all animals. Like others in the field, she is dismayed by cannabis’s current federal legal status. “Unfortunately, research on cannabinoids and animals is delayed due to the status of cannabis and the Controlled Substance Act, which has disallowed research into its medicinal value. CBD has become part of this controversy, even when derived from hemp.”
Initially, Treatibles was sold only through the company’s Treatibles website, but Auntie Dolores has recently been making it available in California medical cannabis dispensaries and local pet retail outlets. Holistic Hound in Berkeley, Calif., is one of the first stores to carry the product. While its name includes the word “treats,” store owner Heidi Hill considers Treatibles to be more closely aligned with supplements— i.e., to have health benefits. She says her customers have given Treatibles an enthusiastic reception, with most reportedly using the edible to alleviate their dogs’ anxiety and, in some cases, pain.
Hill says she gives Treatibles to Pearl, her aging, arthritic Siberian Husky, and has observed an improvement in her appetite and energy level. The quality of its other ingredients—among them, organic, gluten-free oat flour; pumpkin; peanut butter; organic coconut oil and coconut nectar; organic brown rice flour; applesauce; turmeric; and cinnamon— also recommends it, she says.Change Is Coming
While many have seen positive outcomes, some veterinary professionals worry about people extrapolating from their own experiences with medical cannabis to their dogs’ health problems and giving dogs inappropriate amounts. “Sometimes public sentiment and activity get ahead of the scientific background, and that can be dangerous,” Barry Kellogg, senior veterinary adviser to the Humane Society of the United States, has said.
To date, the American Veterinary Medical Association has not taken an official position on the use of medical marijuana with animals. The American Holistic VMA is the first, and so far only, veterinary organization to officially encourage research into the safety, dosing and uses of cannabis in animals. In 2014, the group released a statement that said in part, “There is a growing body of veterinary evidence that cannabis can reduce pain and nausea in chronically ill or suffering animals, often without the dulling effects of narcotics. This herb may be able to improve the quality of life for many patients, even in the face of life-threatening illnesses.”
Other developments are on the way. In March of this year, Nevada state senator Tick Segerblom (D-District 3) introduced Senate Bill 372, which makes a variety of changes related to medical marijuana in the state. Among its provisions is one that would allow officials to issue medical marijuana cards to companion animals whose owners are Nevada residents and whose vet is willing to certify that the animal has an illness that might be helped by marijuana (the illness does not need to be fatal).
California is also in the process of creating a structured regulatory system. In the June 4, 2015, edition of the Sacramento Bee, reporter Jeremy White summarized Assembly Bill 266: “[It] would create what’s called a dual-licensure system, with cannabis entrepreneurs needing to secure permits both from local authorities and from one of a few state agencies. The Department of Public Health would oversee testing, the Department of Food and Agriculture would deal with cultivation and the Board of Equalization would handle sales and transportation—all under the auspices of a new Governor’s Office of Marijuana Regulation.”
According to Constance Finley, the fact that the marijuana industry is unregulated has been part of the problem regarding access. But next year may be the tipping point. If California’s AB 266 is passed and the marijuana industry comes out of the shadows into effective regulation, particularly in terms of verifiable cannabinoid content and freedom from contaminants, the rest of the nation could follow. The state’s size, market potential, and trailblazing environmental and technology industries have historically inf luenced trends nationwide, and that dynamic is likely to drive the discussion in this case as well.
Veterinary professionals are generally in agreement that more study is needed. In a 2013 interview with R. Scott Nolen, Dawn Boothe, DVM and director of the Clinical Pharmacology Laboratory at Auburn University’s College of Veterinary Medicine, commented: “Veterinarians do need to be part of the dialogue. I can see a welldesigned, controlled clinical trial looking at the use of marijuana to treat cancer pain in animals. That would be a wonderful translational study, with relevance to both pets and their people.” (In translational research, laboratory science and clinical medicine combine their efforts to develop new treatments and bring them to market.)
Narda G. Robinson, DVM, director of Colorado State University’s Center for Comparative and Integrative Pain Medicine, agrees. In an email exchange, Dr. Robinson said, “There is a big gap that needs to be addressed between those who are already using hemp products and finding value for their animal and science-based practitioners who want to make sure that their patients are receiving safe and effective treatment. Research will help bridge that gap.”Next Steps
Clearly, veterinarians—our partners in keeping our animals healthy—need a voice in this debate. While interested in the herb’s potential, many are leery about trying it, not only because of the legal consequences but also, because there’s so little evidence-based information. On the other hand, dog owners who have found it useful for themselves feel that not including it in the vet-med repertoire is a missed opportunity.
Although the tide is slowly turning in its favor, the debate about the utility of medical marijuana and its related components for both people and their pets is often mired in personal bias and opinion. Regardless of what position we take, it would seem that the best way to come to a resolution is to focus on the science. Controlled studies that determine cannabis’s therapeutic and toxic ranges in veterinary use and standardization of THC and/or CBD content have the potential to make a potent natural ally legally and safely available to our four-legged companions.
In transforming anecdote to evidence, we can move from what we think, what we believe and what we imagine to what we actually know. That would be a very good thing for us and for our co-pilots as well.

Take a Deep Breath

Somewhere in northern California, a tiny dog is still prancing around on four paws thanks to hyperbaric oxygen therapy (HBOT). Unbeknownst to the dog’s owner, a piece of string had become wrapped around his paw, hidden in the dog’s dense fur. As circulation in the paw slowed down, skin and tissue began to slough off. By the time the owner realized what was happening, the paw was in such bad shape that the little dog’s vet, understandably, recommended amputation. The owner, however, wanted to try to save it. After a strict regimen of cleaning and dressing changes failed to promote significant improvement, the dog was referred for HBOT treatment.
Deep-sea and scuba divers have long used HBOT to combat the bends, and in the medical arena, it has been employed for more than 50 years to help people recover from serious infections and hard-to-heal wounds, among other ailments.
Now, this technology is being utilized to help companion animals and horses with conditions as varied as head and spinal-cord trauma, intervertebral disc disease, wounds and burns, infections, and inflammatory conditions.
The general theory behind HBOT is that it promotes healing by raising oxygen levels in the blood, allowing oxygen to diffuse into tissues at distances three to four times further than usual. Gary Richter, MS, DVM, medical director of Holistic Veterinary Care and Rehabilitation Center, Oakland, Calif., is among those who use HBOT in their practices. According to Dr. Richter, “When there’s inflammation, damaged tissues or injury, lack of oxygen is very commonly the limiting factor. By increasing the amount of oxygen delivered to tissues, we are stimulating these patients’ own healing abilities—immune systems, stem cells—to begin the healing process where other types of conventional medicine might not be able to achieve that goal.” (The dog with the damaged paw was treated at Dr. Richter’s clinic.)
Typically, HBOT treatments last about an hour and are given one to two times daily. A patient is placed in a hyperbaric chamber and breathes 100 percent oxygen at 1.5 to 3 times normal atmospheric pressure. The total number of treatments required depends upon the condition and how the patient responds. Being enclosed in the chamber doesn’t seem to distress the dogs or cats who use it; many reportedly go to sleep during treatment. Dr. Richter thinks that for the patient, it’s mainly boring; “as far as the animal’s concerned, nothing’s happening.” The cost and protocol are the same no matter how large or small the patient.
The therapy has essentially no side effects, although Dr. Richter says that it’s also important to select HBOT candidates appropriately. Dogs or cats with some types of respiratory problems or who are predisposed to specific types of seizures need to be evaluated before undergoing the therapy.
And sometimes, says Dr. Richter, the therapy may have positive side effects. Take, for example, the case of a cat with inflammatory bowel disease (IBD) so severe that she required a surgically implanted feeding tube. The surgical site became infected with Methicillin-resistant Staphylococcus aureus (MRSA), a bacterium responsible for several difficult-to-treat infections. HBOT was used to help the site heal and resolve the MRSA, but as a side effect, her IBD improved to the point that she no longer required intensive medical monitoring.
Despite being approved for use in humans for an array of medical conditions, HBOT is not without its skeptics, who say that the lack of clinical trial data supporting its claims puts it into the realm of experimental. However, based on the human experience, it would seem that HBOT has the potential to become another valuable tool in the veterinary health-care toolbox.

A romp at the dog park, a run along a trail, a walk around the neighborhood--we know how important it is to get our dogs out and about. But how often do we think about exercising our dog's brain? And really, why should we think about it at all?
Recently, I listened to an online seminar offered by Karen Overall, MA, VMD, PhD, DACVB, CAAB, and board certified Applied Animal Behaviorist, that provided several answers to this question.
Dr. Overall starts out by making the interesting point that it's very likely that dogs co-evolved with humans, which was made easier because both species have similar social systems that rely on work and problem-solving. Dogs still need to problem solve but in today's world, probably don't get enough opportunities to do it, which is why we need to provide them with mental stimulation as well as physical exercise.
She then discusses some of her research and shows videos of dogs working a puzzle box designed specifically for one of her projects; she also analyzes what the dogs' performance indicates about their emotional state.
The takeaway is that stimulating a dog's brain by engaging his capacity to problem solve improves both his physical and mental health. It's also key to helping dogs with behavior problems learn new ways to respond to stress.It's science nerd nirvana, a combination of theory and practical advice (most of which comes at the end in the Q&A segment).
The seminar is titled From Leashes to Neurons: The Importance of Exercising Your Dog's Brain for Optimal Mental and Physical Health, and you'll need to register to listen in (registration is free). Get started here: http://vetvine.com/article/192/akcchf-human-animal-bond-event

Oh, the pleasure of reading far into the night. Just one more chapter, or maybe two … next thing you know, it’s three in the morning. How did that happen? For me, suspense novels with compelling main characters written by someone with serious plotting skills are the usual culprits.
Case in point: Alex Kava’s new series featuring Ryder Creed, a man of few words and many, many dogs. Creed is a “dogman,” a former marine K9 handler with tours in Afghanistan on his resume. He and his military dog, Rufus, went ahead of the soldiers to sniff out buried IEDs. Along with Rufus, he brought some of the darkness of that far-away war home with him in his head.
When we meet Creed in the first book (Breaking Creed), he’s on a helicopter with his best multitask search dog, Grace. And here’s the first clue to what makes Ryder Creed different: Grace is a 16-pound Jack Russell, a highly focused and amazingly resilient dynamo whom Creed rescued and trained. In fact, while German Shepherds and Labs are on “staff,” most of Creed’s K9 CrimeScents kennels are filled with what could be called “non-standard” scent dogs; several are mixes, and most are rescues.
Rescue is the underlying theme of these books. Creed was rescued from his post-war drunk and belligerent self, and in turn, takes in and trains abandoned dogs in scent-detection work. Like Creed, some of the dogs have a few rough edges, but also like him, they do their jobs every single time.
Florida is Creed’s home base, and the cases covered in these two books—drug- and people smuggling in the first, shady activities by a top-secret government research unit in the second—both involve the FBI in the person of scarily composed profiler Maggie O’Dell, the lead character in Kava’s other highly regarded series.
A flawed, fierce protagonist whose first and absolute loyalty is to his dogs, plus compelling story lines: a slam-dunk recipe for late-night reading!
Early tactile input pays off
October 4 2015
As our readers know, The Bark is 100 percent in favor of adopting dogs from rescues and shelters. Giving a dog a new life in a home in which he or she is understood, loved and cared for is a giant gift, not only to the dog but also, to ourselves. It's one of those cliched win/win situations: we do something good for a dog and in the process, benefit from the unparalleled companionship that dog provides.
That being said, we also know that every day, hundreds—or more likely, thousands—of dogs are purchased from breeders for a variety of reasons. The most commonly cited reason has to do with predictability: those who buy a puppy from a breeder are looking for some degree of certainty in the adult dog's behavior, trainability and looks. Taking the wide-angle view, that notion has merit, but when it comes to individual dogs, it doesn't necessarily hold up.
I'd like to say that I'm a purist, that I've only adopted, never purchased, but that would be untrue. In my 20s, I purchased a Dalmatian from a breeder who was also a neighbor. All of the pup's littermates had been sold, and at 12 weeks, he was the last one in need of a home. The breeder had determined that he was going to exceed AKC standards in terms of height at shoulder and size of spots (I'm not kidding--she told me his spots were too big) and so decided to sell him as a companion dog. He turned out to be a great dog, one with none of the stereotypical Dalmatian behavioral quirks.
Fast forward 30 years, and I made another foray into purchasing a dog, although not from a breeder, but rather, from an acquaintance whose Siberian Husky had had a litter fathered by a Siberian mix. In that case, I was specifically looking for a Siberian mix for the very unscientific reason that on some level, I was trying to replace a much-loved dog who had died shortly before. I was guided by my heart, not my head.
In both cases, I lucked out—and believe me, the luck was definitely of the "dumb" variety.
The Dalmatian breeder bred her dogs infrequently and carefully, and the pups were well-handled and well-socialized before going to their new homes. The Siberian's people were teachers, not professional breeders. One could be critical of their decision not to spay their female and to deliberately allow her to mate, but in their raising of the puppies who were the outcome of that mating, they were stellar.
Recently, I read a posting from Stan Rawlinson, the UK's "original dog listener." In it, he talks about the impact a breeder has on a dog's adult behavior and health. Following is an excerpt that I found particularly interesting—it also explains why I'd been fortunate in the two dogs I'd purchased: in both cases, the puppies were born in the home and handled extensively from birth.
Humans handling pups from day one provide a mild stress response, which acts to improve the puppies both physically and emotionally. After that at 10 to 14 days the sense of hearing and smell develop, eyes open and the teeth begin to appear.
Their eyesight is not fully formed until seven weeks. Though they can see enough to get round from around three weeks of age. Pups that are handled regularly during the first seven/eight weeks of their life mature and grow quicker.
They are more resistant to infections and diseases, and are generally more stable. These pups handle stress better, are more exploratory, curious and learn much faster than pups that are not handled during this period.
They are also more likely to be happy around humans and are rarely aggressive. Therefore the pups born in kennels outside, and not in the home, and the ones born into puppy farms are less likely to get this vitally important tactile input.
Here's the first take-away: If you care deeply for a specific type of dog and are determined to start with a purebred puppy, it behooves you to pay careful attention to the way the breeder approaches the pups' crucial first weeks of life and the environment in which those pups are being raised. (After that, it's up to you!).
And here's the second obvious-but-true take-away: the value of handling very young puppies early and often isn't limited to purebreds —it applies to all pups of all persuasions in all situations. Hands-on breeders, shelter workers and rescue volunteers improve the odds that their smallest charges get off to a good start .
Dog's Life: Humane
September 15 2015
The first week of September saw a heartwarming example of positive political action when California lawmakers of all persuasions voted to make shelter animals the new official state pet. In both the Assembly and the Senate, the votes were all ayes, no nays.
ACR-56, introduced by Assemblymember Eric Linder (R-Corona), is numbers-driven bill. As it points out, there are currently around 8,000,000 abandoned pets living in animal shelters in the United States, and of these, 3,000,000 to 4,000,000 are euthanized every year.
Like shelters everywhere, those in California stretch to help the animals who come into their care, and it's a big, big job. It's hoped that greater public awareness will get more dogs and cats (and the occasional rabbit, guinea pig or chicken) out of shelter care and into forever homes.
Though the numbers are daunting, keep this in mind: every single adoption makes a difference. The dogs and cats who find new homes also find new lives. For them, it's a 100 percent win.

For years, I kept a supply of phenobarbital on hand, prescribed by my vet for my mixed-breed dog's seizure. It turned out to be a one-time thing, and eventually, I disposed of the drug. But I can testify that watching her in the grip of it was both scary and confusing.
As dog-lovers, most of us hope we're never faced with a number of canine health conditions. Seizures fall into that category. When they happen, however, it's helpful to understand what we're looking at and what we need to do next.
Seizures, which are caused by abnormal electrical activity in the brain, can indicate a variety of conditions, some transitory, some longer-lasting. Our old friend "idiopathic" --or, of unknown origin--also comes into play more than either we or our vets would like.
As explained on the Texas A&M newswire, "For some dogs, a seizure is a one-time experience, but in most cases seizures reoccur. An underlying problem in the brain could be responsible for reoccurring seizures, often resulting in a diagnosis of epilepsy. Between the many causes of seizures in dogs and the often normal lab results, idiopathic epilepsy proves to be a frequent diagnosis." Other causes include toxin ingestion, tumors, stroke, or another of several related neurological disorders.
Dr. Joseph Mankin, clinical assistant professor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences, describes a typical seizure. “The dog may become agitated or disoriented, and then may collapse on its side. It may exhibit signs of paddling, vocalization, and may lose bladder control. The seizure may last for a few seconds up to a few minutes, and often the dog will be disoriented or anxious afterward. Occasionally, a dog may be blind for a short period of time.”
When a dog is in the grip of a seizure, there's little we can do, other than to keep our hands away from his or her mouth. Afterward, the most important thing we can do is take the pup to the vet for investigation into the cause. Fortunately, a number of treatments, ranging from allopathic (Western medicine) to complementary (including acupunture) exist.
Like most things, especially those related to health, knowing what we're dealing with is half the battle.

It looks like we soon may be able to chalk up another win for the power of the canine nose.
In a recent UK National Health Service (NHS) preliminary study, trained dogs were able to sniff out prostate cancer 9 out of 10 times, making them a more accurate predictor than the standard (but controversial) Prostate-Specific Antigen (PSA) screening test, which has a high "false positive" rate.
For men of a certain age, the prostate goes from a background to a foreground worry. The walnut-sized gland circles the neck of the male bladder, and when it starts causing problems, there can be a number of reasons. The most serious is cancer. To arrive at a definitive diagnosis requires a biopsy, which--like any surgery--comes with its own risks. And this is why the "false positive" rate matters: in order to make a decision to go ahead with a biopsy, a man needs to have a pretty good idea that it's needed. The more accurate the screening, the fewer unnecessary biopsies.
Based on the success of the preliminary study, the NHS has recently authorized clinical trials to more definitively test the canine ability to identify prostate cancer. Dogs trained by the group Medical Detection Dogs will be taking part in the upcoming trials. This group, co-founded by by Dr. Claire Guest, was among those profiled in Barbara Robertson's Wonder Dogs article; click on over to read more about it.

Did you know that dogs smell in stereo? You will after watching this terrific animated short from TED-Ed. TED conferences are legendary for the range and quality of their speakers, and their three namesake fundamentals—Technology, Entertainment and Design—converge in the TED-Ed “Awesome Nature” animations. We recently stumbled over one focusing on a dog’s sense of smell, suggested by Alexandra Horowitz, whose book, Inside of a Dog: What Dogs See, Smell and Know, was on the New York Times bestseller list for 63 weeks. Take a look and be enchanted, not to mention enlightened.
Dog's Life: Work of Dogs
Expanding the frontiers of the canine capacity to help us carry on.

We can’t find our glasses, our car keys or the right word. We forget an appointment. We’re unable to bring to mind the name of a long-ago best friend. Many of us jokingly refer to these as “senior moments,” but the humor is only skin-deep. Underneath is the niggling worry that dementia—the term for a set of symptoms signaling a decline in mental abilities severe enough to interfere with our daily lives—lurks. This fear is fed by a sobering statistic: according to the Institute for Dementia Research and Prevention, in the U.S., at least 5 million individuals suffer from age-related dementias (Alzheimer’s disease accounts for roughly 70 percent of the total). These numbers will continue to rise as the population ages.
Severe memory loss is no laughing matter. The brain, a mysterious and complex organ, is, among other things, the repository of the very essence of who we are: our memories. Generally speaking, memory breaks down into three broad categories: sensory, short-term and long-term. Things as dissimilar as childhood recollections and how to walk, hold a spoon or comb our hair reside in our memory As damaged nerve cells (neurons) cease to function, they take much of this information with them. This is where dogs come in.
Dogs love routine. People with dementia have difficulty with routine, everyday activities. Roughly a dozen years ago, two people had the idea to put them together. When Israeli social worker Daphna Golan-Shemesh met professional dog trainer Yariv Ben-Yosef, they chatted about their respective occupations. As Ben-Yosef recalled, “It was clear to us that Daphna’s expertise in Alzheimer’s and my expertise with dogs could result in something new.” Together, Golan-Shemesh and Ben-Yosef pioneered the idea of training dogs to help those with dementia to not only feel better but also, to assist with daily activities.
Fast-forward to early 2012, when Alzheimer’s Scotland secured funding to study the possibility that specially trained service dogs could benefit people in the early stages of dementia. Four students at the Glasgow School of Art developed the initial concept as a service design project in response to the Design Council’s 2011 Living Well with Dementia Challenge. Focused on “finding practical solutions to social problems,” the competition required entrants to “design and develop products and services that rethink living with dementia, and launch them as real initiatives.” The Dementia Dog project grew from this call to action.
Dementia Dog is a collaborative effort, with Alzheimer’s Scotland, Dogs for the Disabled, Guide Dogs Scotland and the Glasgow School of Art pooling their respective areas of expertise. Last year, the research phase was completed, and the group is now in the early stages of a small-scale pilot program. As noted on the Dementia Dog website, the program “aims to prove that dogs can help people with dementia maintain their waking, sleeping and eating routine … improve confidence, keep them active and engaged … as well as provide a constant companion who will reassure them when they face new and unfamiliar situations.”
They are also developing programs for two more assistive functions: intervention dogs, trained to help the client with specifically identified tasks, and facility dogs, who enhance the emotional well being of those living in residential care.
The program’s dogs receive instruction at the Guide Dogs’ Forfar Training School. After 18 months’ work, the first two dementia service dogs—Kaspa, a Lab, and Oscar, a Golden Retriever—were certified last year, and two more dogs are currently being trained.
As noted in the program statement, the dogs help their people with core needs: support for daily living (exercise, balance, alerting to hazards, environmental safety), reminders (prompts to take medication), “soft” support (companionship, a bridge to social interaction, confidence building), and physical and emotional anchoring (staying with their person while the partner/caregiver shops, or helping their person feel safe and secure when alone).
The dogs are also trained to provide another critical service: getting their people home safely. The dogs’ collars are fitted with a GPS unit, and if the person doesn’t give the “home” command, the device helps families or law enforcement zero in on the pair’s location. Unlike guide dogs for the blind, dementia dogs operate at the end of a six-foot leash, which allows them to most effectively steer their people in the appropriate direction.
Dementia service dogs are being trained in the U.S. as well. DogWish.org, a California-based charity that trains and sponsors service dogs, lists “dementia dogs” as one of their training options, as does Wilderwood Service Dogs in Tennessee.
This service dog program taps into our almost primal love for dogs in a very personal way. The dogs of our present, the dogs of our past: their names and quirks and the bone-deep understanding of their nonjudgmental and unconditional love often stay with us when much else has been lost. A person living with dementia may not be able to recall what she had for breakfast or where she lives, but the dogs she loved? That’s another story.
In a 1.28-minute YouTube video clip that’s been viewed by more than 5.6 million people (go to see it for yourself), an elderly man with Alzheimer’s who’s lost almost all of his speech talks to and interacts with the family dog. It’s hard to imagine a better example of the very real value that dogs—purpose-trained or not—provide to the most vulnerable among us.
