Dog's Life: Lifestyle
October 17 2016
While the baby boomer and millennial generations don’t have a lot in common beyond sheer size, they do often intersect around dogs. For different reasons, both groups are more likely to have dogs than children in their daily lives, and tend to consider their dogs as members of the family whose needs are taken into account when choosing how and where to live.
As a result, residential planners, designers and developers are increasingly integrating dog-friendly amenities into their master plans, and programming activities for dog people of all ages.
Inside, elements that make living with dogs more convenient and comfortable are showing up in the form of built-ins that replace crates and provide aesthetically pleasing and convenient gear storage and feeding stations. Transition areas—space off a garage or utility room where dogs can be cleaned up before coming inside— are another popular feature.
Outside, enclosed dog parks are a big draw. Access to safe, roomy off-leash areas close to home and away from traffic are, shall we say, catnip to dog owners. Extras such as sand pits, “splash pads,” and weave poles and tunnels are yogurt icing on the dog-food cake. Wide sidewalks, dog-safe (and dogproof!) landscaping and traffic-calming measures are also popular.
Apartment buildings and condos are getting in on the action as well. Some property developers are incorporating space for dog-grooming facilities (either businesses or tiled rooms with a water source and drying platform where dog owners can do the work themselves), doggie day care or retail pet supply stores into their plans.
Many homeowners’ associations (HOAs) are also coming to see the value of accommodating those with dogs. HOAs that either have a high number of dog people in residence or want to attract them are adding everything from waste stations and pickup bags to dog runs.
Both single- and multi-family housing areas find that a sense of community can be fostered by something as simple as putting up bulletin boards on which referrals for pet services can be shared or found, or by organizing social hours, dog parades or dog-friendly hikes for their residents.
What’s good for dogs can also be good for people; incorporating dog-specific features into residential areas means that those who don’t have or don’t care for dogs can minimize contact if they wish to do so.
In the end, what we look for when we look for a place to live often depends on what matters to us: a pool, an indoor gym, covered parking? If we share our life with a dog, proximity to a safe and convenient place for the dog to get some exercise, particularly a place we can walk to, is very, very high on the list, as is a community with a welcoming attitude.
Community is, in fact, one of the driving forces behind all of these developments. Many of us seek it out, boomers and millennials perhaps more than most. Among their other qualities, dogs serve as social bridges, facilitators of personal connections, even friendships and romances. As this trend continues to gain traction, one day, the “no dogs allowed” sign may be a thing of the past.

Run, Spot, Run
By Jessica Pierce (U of Chicago Press)
Bioethicist Jessica Pierce, whose book The Last Walk thoughtfully and honestly explored end-of-life care, dying and euthanasia for companion animals through her experience with her own much-loved dog, now takes on another sensitive subject. As in that book, in her new one she also addresses questions we rarely think about—or want to think about. Foremost among them is the morally ambiguous practice of keeping pets in the first place. Writing clearly, and clearly from the heart, she avoids academic jargon and provides us with reasons to really think about what we’re doing when we take animals into our lives.
The Pit Bull Life
By Deirdre Franklin and Linda Lombardi (The Countrymen Press)
A colorfully illustrated and thoughtful consideration of a type of dog who was once considered quintessentially American. Today, however, the words “Pit Bull” have become shorthand for something to be feared. The authors trace that transition and, continuing Franklin’s long-standing advocacy, inject the facts about these cheerful, resilient dogs into the national discussion. In doing so, they also provide a primer for Pit Bull owners, and potential owners.
By Neil Abramson (Center Street)
In this novel, the author considers the balance between fear and compassion, and the ways politically expedient solutions threaten everyone. The story centers on a sanctuary for unwanted, abused and abandoned dogs in New York City and the veterinarian who operates it. When a dangerous and unknown virus spreads though their neighborhood, the sanctuary’s dogs are presumed to be the carriers, putting them and the people who protect them in even greater jeopardy. The pace is intense and the characters well drawn.
The Secret Language of Dogs
By Victoria Stilwell (Ten Speed Press)
In her new book, trainer Victoria Stilwell wants to help us understand what our dogs are telling us via their expressions, vocalizations and behaviors. A proponent of positive reinforcement training, Stilwell not only describes these various methods of communication but also, provides tips on ways to respond to them.
By Janet Vorwald Dohner (Storey Publishing)
An in-depth and beautifully illustrated breed guide to a hard-working class of dogs, Farm Dogs is hard to resist even if you live in a city apartment only big enough for a Chihuahua. In addition to familiar breeds such as the Jack Russell, German Shepherd and Border Collie, Dohner also discusses a number of more exotic types, including the Berger Picard, Mudi and the wildly dreadlocked Puli. She also offers pointers on puppy selection, adult rescue, socialization and training.
Home Alone—And Happy!
By Kate Mallatratt (Hubble & Hattie)
This highly illustrated book from the UK provides lots of good advice for preventing canine separation anxiety, which is far more challenging to fix than to avoid. The author, compassionately considering the subject through a dog’s eyes, suggests that teaching a dog how to be emotionally stable is more important than teaching him how to sit or heel. In this book, she shows us how to do it.

War is hell, the saying goes, and not just for soldiers. The highly trained military dogs at their side pay an equally severe price. Sculptor James Mellick has memorialized these dogs— and through them, the soldiers with whom they served—in a series of seven life-sized works. The Doberman missing a foreleg, a German Shepherd with a prosthetic paw, a Belgian Malinois with a metal plate: as hard as they are to contemplate, these dogs seem undaunted, a testimony to Mellick’s sensitivity and dogs’ innate, in-the-moment nature. Carved from cherry, poplar, sycamore, walnut and cedar, the sculptures came to life through a long process of designing, laminating, carving and finishing. Fine details—the bone structure under the fur; the curve of a leg; expressions conveyed by the eyes, brows and ears—are informed by Mellick’s lifetime with dogs as well as his current canine housemates, a Weimaraner and a rescued Lab/Weimaraner mix.
In his sculptural work, he says, his intent is to “reach a unity of shape and content, so that the secondary forms and shapes within the body of the dog not only serve as symbols of the meaning, but are also important design elements in the composition.”
This isn’t Mellick’s first dog-related artistic foray; he’s been investigating and experimenting with dogs as metaphors for more than 30 years. His first was Stacking Dogs (1985), a 12-foot tower of dogs ranging from an Irish Wolfhound to a Chihuahua, a comment on human arrogance, he says. His Canine Allegory Series (1997) also reflects his belief in dogs as talismans. “I see the dog as a totem animal of humans, a parallel self, if you will, who has the goods on us. Think about the dog’s unconditional love, trust, vulnerability, and the therapy and healing they offer. Look into their eyes and they are either saying ‘I love you’ or ‘What the hell are you doing?’”
He displayed three of the dogs—two German Shepherds and a Malinois—at the 2015 Vietnam Dog Handler Association reunion in Nashville. The veteran dogmen were drawn to them, Mellick says. “The dogs were a big hit, with the guys taking selfies with them, and many, many conversations took place around them. Men were wiping tears away. They released many emotions that had been locked up.” Their reactions aren’t hard to understand. Military dog-team jobs have always been dangerous: detecting explosives, scouting the enemy and taking part in search-and-rescue missions. Many don’t survive, and those who do tend to be deeply affected by the experience.
Mellick feels strongly about our nation’s ambivalent response to the men and women who serve in the military. As he told an interviewer earlier this year, “It’s one thing to be against war, but things really go south when people turn against the soldiers who serve. Young people today put themselves in harm’s way not because they were drafted but because they’ve volunteered. And because there is no draft, many of us don’t see the cost and we don’t feel the pain.”
In Wounded Warrior Dogs, Mellick makes us look straight at things we’d probably prefer to avert our eyes from—he makes us feel the pain and see the cost, both to the war dogs and their battlefield partners.

We may think our dog wIll take a treat from any hand that offers it, but a new study by a team of Japanese researchers suggests that may not be the case. Primates engage in something called “social eavesdropping”— essentially, making judgments about others based on interactions that don’t directly affect their own interests. This study tested dogs’ ability to do the same by setting up situations in which the dogs’ owners asked for help in opening a box and were assisted (helper scenario), rejected (non-helper scenario), or ignored (control scenario) as the dogs looked on. After these interchanges, when the dogs were offered treats, they took them randomly from Helper and Control “strangers” but were biased against non-helpers. According to Kazuo Fujita, professor of comparative cognition at Kyoto university and one of the study’s authors, the ability to socially and emotionally evaluate others “is one of the key factors in building a highly collaborative society.” So, another step in the process of understanding how Canis lupus became familiaris: like humans, dogs are able to pick up clues about who to trust and who to avoid.
The Bark's Spring 2015 issue

This seven-year-old German Wirehaired Pointer lives in Southern California at Skye Valley Ranch, near the Mexican border. Although she loves to run—she’s reported to be the fastest of the ranch’s dogs—her favorite activity seems to be taking in the sights from the ranch tractor’s passenger seat. At the end of the day, she can be found inside, curled up on her bed near a warm fire.
According to her family, Abby didn’t have a chance to do much hunting when she was young, but did develop a fondness for fishing. The ranch has a lake, and she’ll patiently stand for hours in its shallows, intently focused on the perch swimming around her legs.
We were particularly taken with this account from Abby’s person: “Abby became part of our family while I was pregnant with our only child, Katie, and has always been more of a protector or guardian than playmate. From early on, her sense of duty was evident. One day, when Kate was a toddler, Abby found a small rattlesnake in the grass and started barking and growling and biting it and throwing it up into the air. She was bitten and had some swelling on her lip, but got the vaccine and recovered just fine in a couple of hours. We were not expecting such a sense of duty from a Pointer.”
Cover photographer Kaylee Greer is known for her love of vibrant color and her love for dogs; in addition to her commissioned work, she volunteers her talents, providing photos that help shelter and rescue dogs—both in the U.S. and in other countries—get noticed and adopted. Greer, who says she’s fueled by dogs’ purity, joy and unrelenting happiness, is scheduled to teach a series of workshops this spring.

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
December 12 2015
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!
