Protecting Your Dog Against Foxtails
Dog in Foxtails

Tonight my littlest dog Nellie came in the house sneezing. Any other time of year and I would be unconcerned, but in late spring and early summer an abrupt onset of sneezing after being outdoors is a “foxtail-in-the-nose alarm bell.” I’ll be watching Nellie like a hawk for the rest of the evening. Any crinkling of her nose, ongoing sneezing or bloody nose, and she’ll be my first patient tomorrow morning.

If you are unfamiliar with foxtails, count your blessings! These pesky, bristly plant awns grow in abundance throughout California and are reported in most every state west of the Mississippi. Once the plant heads dry, they become hell-bent on finding their way into dogs’ noses, ears, eyes, mouths and just about every other orifice. They can dive deep into a dog’s nostril or ear canal (beyond sight) in the blink of an eye. And a foxtail camouflaged under a layer of hair can readily burrow through the skin (a favorite hiding place is between toes). Foxtails can wind up virtually anywhere in the body, and associated symptoms vary based on location. For example, a foxtail within the ear canal causes head shaking, under the skin a draining tract, or within the lung, labored breathing and coughing. Not only is the dog’s body incapable of degrading or decomposing foxtails, these plant awns are barbed in such a way that they can only move in a “forward” direction. Unless caught early, they, and the bacteria they carry, either become walled off to form an abscess or migrate through the body causing infection and tissue damage. Once foxtails have moved internally, they become the proverbial needle in a haystack—notoriously difficult to find and remove.

Take the example of Emma Louise, an undeniably adorable Brittany Spaniel mix whose family told me that her favorite pastime is running through fields with her nose to the ground. They described her as a “foxtail magnet,” having accumulated several in her ears and nose over the years. I was asked to help figure out the cause of Emma Louise’s hunched back and straining to urinate. With abdominal ultrasound, I discovered a gigantic abscess tucked up under Emma Louise’s spine, extending into her pelvic canal. Given this girl’s history, I just knew there had to be a foxtail in there somewhere. The question was, would we be able to find it?

As is my medical tradition before launching a foxtail search, I recited a prayer to the “god of foxtails.” I then turned Emma Louise over to one of my surgical colleagues for exploratory surgery. After two hours of nailbiting and a barrage of expletives originating in the O.R., I heard a shout of, “Got it!” The foxtail had been located and removed, and sweet little Emma Louise made a rapid and complete recovery. Not finding the foxtail would have meant a lifetime of antibiotics to treat her foxtail-induced infection.

If you suspect your dog has a foxtail-related issue, contact your veterinarian right away to find out what steps can be taken (at home or in the veterinary hospital) to rid your dog of this unwanted plant material. Whenever possible, avoidance of foxtail exposure is the best and only foolproof prevention. If your dog does have access to foxtails, carefully comb through his or her haircoat—checking ears and toes, too —a couple of times daily to remove any that are embedded and poised to wreak havoc!

Canine Seizures
Out of the blue, your dog rolls on his side and starts to shake. What’s going on?

Charlie, a four-year-old Shih Tzu mix, held his head low and cried out when touched. His regular veterinarian performed blood tests and took X-rays, none of which revealed a reason for the neck pain. After discussing possible causes—a slipped disk and meningitis among them—the vet prescribed a trial of antibiotics and pain medication. At first, Charlie improved, but within a few days, his pain seemed to increase. Then he had a seizure.

His people rushed him to a local emergency clinic, where he was admitted. The clinic kept Charlie overnight to stabilize him, and the next day, transferred him to our practice, Southeast Veterinary Neurology in Miami, Fla.

Charlie was minimally responsive. When we examined him, we saw that he tended to turn his head to the left and didn’t react to stimuli on the right side of his body; he didn’t blink when touched near the right eye or when his right eye was approached. After a magnetic resonance imaging (MRI) and spinal fluid analysis, we had a diagnosis: encephalitis. Treatment was started immediately.

Seizures—a manifestation of uncontrolled electrical activity in the cerebral cortex—are the most common canine neurological disorder. The cerebral cortex is made up of cells (neurons) that communicate with each other via electrical activity. A seizure happens when that electrical activity becomes excessive or uncontrolled.

Seizures are classified as either focal or generalized, with the latter being the most frequently seen. In a classic generalized seizure, all four legs become stiff and the dog lies down or falls over before losing consciousness and convulsing. During a convulsion, many dogs will vocalize and salivate; some will urinate or defecate. The seizure may last anywhere from a few seconds to several minutes, or longer.* Focal seizures are milder and only affect one part of the body—part of the face, or one leg.

Any disturbance that either increases the electrical activity in the brain or decreases the control mechanisms that prevent seizures can cause these episodes. There are three basic types of disturbances: extracranial (problems outside of the brain that secondarily affect the brain), intracranial (physical or structural problems with the brain itself) and idiopathic epilepsy.

Low blood sugar, severe liver or kidney disease, electrolyte abnormalities such as low calcium, and toxins/poisons are among the causes of extracranial seizures. All of these conditions are relatively easy to identify with blood and urine tests.

Intracranial causes include brain tumors, strokes, encephalitis/ meningitis (as in Charlie’s case), head injury or a malformation such as hydrocephalus (“water on the brain”). Diagnosing these conditions requires an evaluation by a neurologist, an MRI of the brain, and possibly a cerebrospinal f luid analysis. Seizures experienced by certain breeds of dogs—including Boxers, Yorkshire Terriers, Maltese and other terriers—are more likely to have an intracranial cause.

Idiopathic epilepsy—seizures with no known cause—is the most common reason for recurrent seizures, and is the result of an inherent hyperexcitability of the neurons of the cerebral cortex. In general, dogs with idiopathic epilepsy are between one and five years of age when they have their first seizure, which is usually of the generalized type. In between seizures, they’re completely normal, as are their neurological examinations.

Seeing your dog have a seizure can be distressing, but the primary thing you need to do is to remain calm. Do not put your hands near your dog’s mouth, as in the throes of a seizure, he’s not aware of his actions and may unintentionally bite you. Keep your dog in a safe area where he is unlikely to hurt himself, moving him away from stairs, pools or other hazards. If this is your dog’s first seizure, take him to your veterinarian immediately.

Your vet will likely start with a series of blood and urine tests to evaluate the liver, kidneys, electrolytes and other internal organs, looking for an extracranial cause. A consultation with a veterinary neurologist and an MRI may be recommended if the blood tests are normal, if your dog is younger than one or older than six, or if he acts abnormally between seizures.

Diazepam (Valium) or midazolam, fast-acting drugs, will halt a seizure in progress. Depending on the cause and the dog’s response to treatment, longer-acting anti-seizure medications are also prescribed. Among these are phenobarbital, potassium bromide, levetiracetam (Keppra), zonisamide (Zonegran) and felbamate (Felbatol); each has both positive and potentially adverse effects. Your veterinarian or neurologist will discuss which medication makes the most sense for your dog. For many conditions, including idiopathic epilepsy, medication can help reduce the frequency and severity of seizures, but some seizure activity can still be expected.

Seizures are indeed scary, but understanding their causes and knowing what to do when they occur go a long way toward successfully coping with them.

*Ed. note: According to other sources, a seizure that lasts more than five minutes or that reoccurs three times in a 24-hour period should be considered an emergency.

Are Some Dogs Hardwired to Overeat?

Researchers at Cambridge University looked at Labrador Retrievers (the most popular breed in the U.S. and the UK) to assess why that breed is more prone to obesity than other breeds. Their findings, recently published in the journal Cell Metabolism, point to a possible genetic reason behind this.

“About a quarter of pet Labradors carry this gene [difference],” lead researcher Dr. Eleanor Raffan noted. “Although obesity is the consequence of eating more than you need and more than you burn off in exercise, actually there’s some real hard-wired biology behind our drive to eat,” she added. Labs have the greatest documented obesity prevalence.

More than 300 Labradors, from pets to assistance dogs, were screened for known obesity genes in the study. The international team found that a change in a gene known as POMC was strongly linked with weight, obesity and appetite in both Labradors and Flat-Coated Retrievers.

Other breeds—from the Shih Tzu to the Great Dane—were also screened, but this particular genetic difference was not found.

Dr. Giles Yeo, was one of the human geneticists from the University of Cambridge, who worked on the study. “What we have found is that some Labradors get fat because they have a deletion in a gene within their brain,” he said.

“And this particular gene plays a role in sensing how much fat they have in their body—and so some Labradors don’t know how much fat they have and so keep eating to try to get fatter.”

Researchers also found that the mutation is significantly more common in Labradors selected to become assistance dog breeding stock than those selected to be companions.

It is certainly intriguing why assistance Labs are more prone to be carrying this gene deletion, but as they hypothesized, dogs carrying the POMC deletion may be more likely to be selected as for work as assistance dogs because trainability and temperament are the main “drivers for selection of these dogs, and positive reinforcement with food reward is the mainstay of puppy training.”

Six Tips on Caring for Older Dogs
We look at ways to make their lives easier.

In your eyes, your dog will alway s be a puppy, even if she’s getting up there in canine (and human) years, or her muzzle is beginning to gray. However, eventually the day will come when you notice that your pup is panting a little bit harder after a long walk and struggling to climb onto your bed. It’s time to start adjusting to the lifestyle needs of an older dog.

When a dog is considered a senior largely depends on breed. Smaller dogs (such as Chihuahuas or Terriers) don’t reach their golden years until they’re 10 or 12, while a Great Dane may attain senior status at the age of five or six. Beyond size and breed, genetics, diet and environment all have an impact on a dog’s life expectancy.

Just as modern medicine has extended the lives of people, with the right combination of attention and preventive care, it can also extend the lives of dogs. If you want your older dog to have a long and happy life, consider incorporating these strategies into your pet care routine.

Remember your dog’s teeth. Dental hygiene is particularly crucial as your dog ages. Regular brushing and professional cleaning can prevent painful dental disease and decay (and help your dog avoid the chewing problems mentioned earlier). If your dog doesn’t enjoy having his/her teeth brushed, consider dental treats and toys instead.

Watch your dog’s diet. Mature dogs often have food issues, including problems chewing, lack of appetite, obesity and digestive difficulties. Consult with your vet on the best diet and exercise plan for your aging dog. Dietary changes may include adding more fiber to aid with digestion or decreasing carbohydrates to maintain optimal weight. Supplements such as fish oil or glucosamine can be added to alleviate joint pain.

Exercise your dog’s body and mind. Like people, aging dogs experience pain and have difficulty performing physical activities they used to enjoy. However, exercise continues to be imperative to their health and well being. Take your dog on short, gentle walks and monitor his/her breathing and gait to make sure nothing is amiss. Your dog’s brain needs plenty of exercise as well. Stimulating toys such as food puzzles help keep your dog sharp.

See the vet more often. Take your dog in for a vet checkup at least twice a year. Just as elderly people need to be aware of health issues and visit their doctors more often, aging pets benefit from more frequent visits. Older pets may need additional blood tests, dental care and examinations. Additionally, many breeds have predispositions toward certain ailments, including arthritis, hip dysplasia, cancer and diabetes. Early detection can help catch these before they become major problems.

“Seniorize” your house. Just as you once puppy-proofed your home, you now need to provide your older dog with special accommodations. For dogs with hip dysplasia or joint issues, consider a special ramp or stairs so they can still get in the car or join you on the bed. Keep food and water in areas they can easily reach, especially if they are vision-impaired. Heated beds can soothe achy joints, particularly if you live in a colder climate. Finally, non-slip surfaces will prevent falls and help your older pet maintain traction when rising.

Pay attention. Monitor changes in behavior; appetite; weight loss or gain; dental issues; and any lumps, bumps or lesions and bring them to your vet’s attention. (A journal is a great memory aid.)

Taking care of an older dog may involve a little more work than you’re used to doing, but caring for a lifetime companion is a deeply rewarding experience. Your dog has been good to you (and for you) for years—now’s the time to return the favor!

Fighting Valley Fever
Chocolate lab sits on the dried grass. Discussions of Valley Fever in Arizona's research group.

Arizona genetics researchers are taking the unusual step of asking for dog lovers’ help in fighting a mysterious, potentially lethal infection that plagues both dog and man.

They are looking for dogs to be registered and potentially to have their DNA collected to help combat valley fever, a fungus-based disease once confined to the Southwest desert but is now spreading across the country.

Valley fever can be triggered by inhalation of just a handful of spores of a particular fungus. People, dogs and cats are susceptible to the illness that was once believed to occur only in Arizona and California. The disease is not contagious and is not spread from species to species.

The risk for valley fever increases as climates get drier, say California State University, Bakersfield researchers. Warmer temperatures and less rain basically kill off the fungus’ competitors for nutrients and thereby creating an ideal growing environment for the infection-causing fungus.

Valley fever is now being reported in states such as Michigan, Ohio and Minnesota, which never used to see the condition. And the states that typically see the condition are reporting more and more cases: The number of Valley Fever reports is increasing in more than a third of California’s  counties, putting more dogs at risk for a disease that can lead to lameness, extreme weight loss and coma.

When Charlie, a 75-pound Chocolate Lab, started coughing, it didn’t set off any alarms. But then he developed a fever and was diagnosed as having kennel cough, which can be easily treated by antibiotics and steroids. Then the symptoms returned and again it was misdiagnosed as pneumonia. More than two months passed before Charlie was given the correct medication; the delay in a correct diagnosis lessens his chances for a full recovery.

Charlie now spends most of his time sleeping off the effects of valley fever, instead of being his normal playful self.

There is no cure for valley fever. Currently treatments focus on helping dogs beat the symptoms. Vet bills can mount up since a dog may have to get medication for up to eighteen months; in some severe cases, a dog may be on medicine for the rest of his life.  It is estimated that Arizona dog lovers spend $60 million per year in caring for dogs with valley fever.

Seeing the increase in valley fever cases across the U.S., Phoenix-based Translational Genomics Research Institute (TGen) researchers are now asking for dog people to take a brief online survey about their pet’s breed, health history and lifestyle. After the survey, the dog may be selected to give a saliva sample.

Then after the swabbing is done, researchers will look for differences in the genes of dogs who are sick compared to dogs who show signs of exposure to valley fever but who aren’t sick.

“In certain dogs, a minor infection can progress to severe disease, and the reasons for this are unknown,” said Dr. Bridget Barker, assistant professor and head of TGen’s Northern Arizona Center for Valley Fever Research in Flagstaff, Ariz.

This information would be used to help develop new therapies for both dogs and people, she said.

Acupuncture Can Help Dogs
Holistic Medicine
Back Problems / Acupuncture

Intervertebral disc disease (IVDD)—what some call a “slipped disc”—can smolder or it can strike full-blown, leaving your dog in excruciating pain and unable to walk. Initially, signs that a dog is afflicted can be subtle: a hesitation about going up or down stairs, paws that knuckle under or cross over, nail scuffing, an arched back, a tense abdomen. Dogs may shy from their food bowls to avoid bending their necks, or cry when picked up.

IVDD causes compression of the spinal cord and leads to weakness, pain and sometimes paralysis, and is divided into two categories: Hansen Type I and II. Type I often swoops in suddenly, usually in younger, smaller dogs ages three to six. The center jelly of the vertebral disc, called the nucleus pulposus, degenerates, then ruptures and presses on the spinal cord. Not surprisingly, the chondrodystrophic breeds (dogs with short legs and longbacks)—Dachshunds, Corgis, Lhasa Apsos, Shih Tzus and Beagles—are predisposed to this type.

Type II, which is typically seen in large dogs like German Shepherds, Labradors and Dobermans ages eight to ten, progresses more slowly. Though the disc doesn’t burst its center, it bulges between the vertebrae and impinges on the spinal cord, causing chronic pain and weakness.

To rule out fractures, bone infections and cancers, your vet will start with X-rays, but a contrast myelogram, CT or MRI (all of which are often done at specialty centers) is needed to visualize the spinal cord and determine the nature and location of the problem.

In addition to type, IVDD is described by level of severity. Roughly, grade I involves pain; grade II, unsteadiness; grade III, weakness that prevents standing or walking; grade IV, paralysis but able to feel deep pain when the toes are pinched; and grade V, complete paralysis with loss of deep pain.

Dogs with grades 1 through IV will likely be managed with pain meds, muscle relaxants and strict rest for up to a month, and are often referred for physical therapy or Class IV laser treatments. Depending on the duration of neurological deficits and amount of pain, surgery may also be recommended for dogs with grades II, III and IV. Because the disease can change quickly, even dogs diagnosed with lower-grade IVDD need sequential exams to ensure that the condition is not progressing.

When a dog is completely unable to walk, decisions have to be made swiftly. Dogs who stay in the grade V stage longer than 48 hours often remain paralyzed despite intervention, while up to 50 percent of those who have surgery in the first 24 hours may regain their ability to walk.

IVDD surgery removes compromised discs, hemorrhage and adjacent bone compressing the spinal cord. With severe disease, it’s the best chance for a dog to walk again. It does, of course, also entail expenses and risks that not everyone is able or willing to undertake. What other options do we have?

Thankfully, veterinarians have been studying other modalities to treat IVDD, acupuncture among them. In 2007, a team lead by A.M. Hayashi found that dogs of all IVDD grades recovered more quickly with electroacupuncture (EAP) combined with a standard Western medical approach than Western treatment alone (JAVMA 231[6]: 913–918).

In 2009, A. Laim et al. reported that dogs receiving EAP and pain medications after surgery for acute IVDD were less likely to need higher doses of pain meds during the first 12 hours than those who received meds alone. These patients also had significantly lower pain scores 36 hours after treatment (JAVMA 234[9]: 1141–1146).

A 2010 study compared three options for IVDD dogs with severe neurologic deficits of greater than 48 hours’ duration: decompressive surgery (DSX), EAP, and DSX followed by EAP (DSX + EAP). The study, led by J.G.F. Joaquim, showed that EAP was more effective than DSX + EAP, and that DSX alone was the least successful. These dogs had severe, long-standing IVDD in the thoracic and lumbar (thoracolumbar) spine, and in the past, their prognosis would have been dismal. (JAVMA 236[11]: 1225–1229).

How does acupuncture work? While there is some debate over definitions, it’s generally accepted that acupuncture points (acupoints) concentrate clusters of free nerve endings, small blood and lymphatic vessels, and mast cells, part of the immune system. A veterinarian certified in acupuncture inserts small, sterile needles into specific points to stimulate muscles, nerves, circulation and the immune system. For IVDD, one needle may be placed at the top of the spine by the shoulders, and a second above the pelvis, which moves the qi and stagnated energy caused by the disc disease.

Functional MRIs reveal that acupuncture activates pain-associated brain stem regions. The specific mechanism of acupuncture on IVDD has not yet been fully explained, but it’s surmised that it reduces local swelling, inflammation and pain; decreases cord compression, scar formation and tissue oxygen deprivation; and restores damaged nerves.

When compared to the use of needles alone, EAP has been found to increase the body’s response to acupuncture. In EAP, needles in the skin are connected by metal clips; electro-impulses move between the clips and into the needles, producing sensations that range from a tingling to a vibration. Frequency and intensity are determined by the type of condition being treated. Sessions usually last from 10 to 30 minutes, and dogs often fall asleep during treatment.

EAP has a cumulative effect and is typically prescribed as a series of treatments, every one to two weeks for at least a few months. Appropriate Chinese herbal formulas are often prescribed at the same time to reduce pain and enhance the effects of acupuncture. Dogs then proceed to maintenance acupuncture at one- to three-month intervals to prevent recurrence.

Ideally, your dog will never go through the pain of IVDD, and you won’t have the worry. But if you do find yourself up against a down dog, it’s good to know that adding acupuncture to the treatment repertoire may help your friend get back on all fours.

New Life-Saving Law in Florida
It’s now legal to break into cars to rescue pets and people

The governor of Florida just signed a law making it legal to break into a car to rescue a person or a pet who is “in imminent danger of suffering harm.” It applies to vulnerable people and pets (including cats and dogs), but does not apply to farm animals. Many people and pets die each year because they have been left in overheating cars, so this law could save many lives. It is especially important in a hot southern state like Florida with the summer months approaching.

The law specifies procedures that must be followed in order for a person breaking into a car to be protected from civil liability for damage to the vehicle. If you are trying to help someone in danger, here’s what you should know about the law. It is required that you check that the car is locked before breaking in. If you do break in, the law requires that you do so with the minimum force necessary. You are required to call 911 or law enforcement before or immediately after rescuing the person or pet from the car, and you must stay with the rescued pet or the person until first responders arrive.

I’m delighted to know that Floridians are now protected by this law if they see an individual in danger in a car and choose to act. Many people would rescue the pet or person regardless of the risk to themselves, but it’s far better to give legal protection to  such potential heroes.

Calories Count

Winter not only keeps us inside, it’s also a time of food-centric holiday celebrations. How can we share the fun with our dogs without packing pounds on them? When you want to get the facts, you go to the pros, and for an answer to this question, we checked in with Julie Churchill, DVM, PhD, ACVN and associate professor of nutrition at the University of Minnesota Veterinary Medical Center. Her general advice is that we be mindful of our dogs’ daily caloric needs and their total intake. (More on this in a future issue.) Dr. Churchill also shared a few tips.

> Go for frequency, not volume, and choose either very small treats (pinkie fingernail-size) or ones that can be broken into small pieces.

> Look for tasty low-cal alternatives; if your dog likes likes raw fruit and veg —carrots, celery, green beans, cucumbers, apples, blueberries—keep a ready-to-eat supply on hand.

> Unsalted, unbuttered popcorn provides lots of bang for its caloric buck; there are only 20 calories in a popped cup, and a cup goes a long way, especially when scattered around for the dog to find.

We saved the really big question for last. How do we resist those soulful eyes as we eat our turkey sandwiches and our special holiday cookies? Dr. Churchill advises that if we’re going to cave, we should do it with the lowest-calorie treat. It’s also important to avoid reinforcing begging (do your best!) and to preserve our dog’s routine. Dr. Churchill’s final takeaway: Dogs choose joy, and the time we spend with our dogs means more to them than food. Carve out time to make some joyful memories.

Exploring the Humane and Canine Microbiome
Q&A with Dr. Robynne Chutkan

Dr. Robynne Chutkan, one of the leading gastroenterologists in the country, is the author of a new book, The Microbiome Solution, in which she takes us on an exploration of our guts’ ecosystems. Her rousing endorsement of “living dirty” includes the benefits of living with dogs. Bark’s editor speaks with her about just how helpful dogs are to our health, inside and out.

Is it true that there are similarities between our microbiome and those of our dogs, and that dog-owning families have more diverse microbial colonies than dogless households?

Although we share many of the same microbes, dogs in general have a more diverse microbiome than we do. Not surprisingly, some of their additional species are soil microbes (rolling in the dirt from time to time may be a habit worth copying!). Close contact with our dogs is hard to avoid, and that’s a good thing, because they end up passing on some of their unique microbes to their owners, giving dog-owning households a microbial boost.

Dog owners who have children share more mouth bacteria with their dogs than they do with their children. Is this a good thing?

The microbiome in children under the age of three is still developing and as a result, is very different from that of an adult, although there are still lots of shared species with household members (and pets), given the proclivity children have for [putting] everything in their mouths. So, most adults (not just dog owners) have a very different microbiome from their young children. As children get older, their microbiome starts to more closely resemble that of the other household members—not just parents, but pets, too. The vast majority of microbes our canines pass on to us are helpful or benign, not harmful, so keep those doggie kisses going.

So bacteria aren’t species-specific? Is that why, as you note, owning a dog is a highly effective way to replenish and revive bacteria that are basically under attack by modern-day living?

Some bacteria are species-specific, but many are shared by both humans and dogs. Most dogs are much more in touch with the natural world than their owners are, and that’s exactly where lots of the health-promoting microbes come from: soil; unfiltered, unchlorinated water; and, of course, the poo of other animals that our dogs are constantly checking out. Dogs tend to go easy on the hand sanitizer and antibiotics and eat a less processed diet (all habits worth emulating), so they haven’t super-sanitized away as many of their microbes as we have. Some of these canine microbes can be passed on to us, helping to replenish our lackluster microbiome.

The high-fat, low-fiber food we eat, attracts a different range of microbial types; do you know if that is the same for dogs?

I’m not aware of any specific studies looking at variations in canine diets and the effects on their microbiome, but certainly, dogs who eat more processed grains and other foods not natural to their diet tend to have more health problems, and the same is true for humans.

You mention that it’s okay to be a little dirty and sweaty. Why do you think Americans are so obsessed with being hyper-clean?

In the pre-antibiotic era, epidemics of the plague, cholera and other highly infectious diseases wiped out vast numbers of people. The advent of penicillin in the 1930s is still one of the most important contributions to modern medicine, and antibiotics have saved countless lives. But now the pendulum has swung the other way; we’re currently in an era of overdiagnosis and over-treatment, and we’re seeing the emergence of new “modern plagues,” not from infection, but from not enough microbes.

However, the public still sees antibiotics as the life-saving miracle workers they were in the first part of the last century, not as the overprescribed menace they’re becoming. Plus, 80 percent of all antibiotics sold in the U.S. are used in the livestock industry, mostly to fatten animals for slaughter. Clearly, that’s not a lifesaving endeavor.

I think the pharmaceutical and personal-product companies also have a lot to do with it. They’re responsible for many of the public-health campaigns that incorrectly equate cleanliness with health, and of course, they make billions of dollars selling hand sanitizer and other anti-bacterial products.

It’s not just okay to be a little sweaty and dirty, it’s great for your microbiome and your overall health. We need exposure to dirt and germs (bacteria, fungi, protozoa and so forth) to train our immune systems to recognize friend from foe. Not enough exposure to germs, especially when we’re young, leads to a confused immune system that tends to overreact. The result is allergies and autoimmune diseases.

In defense of less bathing and shampooing: your body is really good at concocting the exact formula needed to keep your skin and hair moisturized and healthy. But what do we do? We scrub away our natural oils with harmful antibacterial products and then try to revive our skin and hair with store-bought products full of chemicals. Live dirty for a healthier— and better looking—you!

Many studies have shown the benefits to children of having a dog, including a decrease in eczema and asthma. Why else would you recommend that a family get a dog?

Having a dog is great for reducing stress and anxiety and lowering blood pressure. And we already know they improve the microbiome of the entire household.

What’s your personal dog “biome”?

My mother’s bridge partner, Eva, worked for the Swedish embassy, and when she moved back to Sweden, she left her beloved German Shepherd, Trygg, with us. He’d been used to spending all his time with Eva, and became immediately attached to my mom. We had to be super vigilant in the bathroom because he loved to drink from toilets (all kinds of rewilding going on!).

Hugo, our German Shorthaired Pointer puppy, came into our lives about six months ago. Getting a dog forced me to slow down my too-busy lifestyle and spend more time sitting on my front steps, stroking Hugo and literally smelling the roses. He’s super active, so my husband and I take turns running with him in the mornings and evenings.

We live near Rock Creek Park in Washington, DC, so, thanks to Hugo, there’s a whole lot of dirt and sweat happening on a daily basis. Our daughter Sydney loves him so much that we really can’t imagine life without him.

Hugo slobbers over everyone he comes into contact with, and since I frequently have meetings with the Gutbliss team at our house, he’s become our CRO—Chief Rewilding Officer!

Mackerel Makes Great Toppers

Rick Woodford, the man behind dogfooddude.com, is back with another highly informative, yet easy-to-use cookbook. His new, aptly titled Chow will enable even absolute beginners to try their hand at whipping up whole meals, or simple nutritious and delectable “toppers” (like the one here), for their dogs. Nothing says loving better.

Greyhound are known to reach speeds up to 45 miles per hour, making them one of the fastest breeds around. They’re perfect for running in a straight line or chasing prey, but as soon as the race is over, the greyhound is ready to take a nap. The Alaskan husky can achieve speeds about half that of the greyhound but can sustain the speed for much longer—all while pulling a sled. Both breeds are remarkable for their achievements, but are hardly interchangeable for the unique requirements needed in each racing environment.

Omega-3 fatty acids can be sourced from either plants or animals, and like the greyhound and husky, the different sources have different purposes and benefits. Flaxseeds, chia seeds, and pumpkin seeds contain alpha-linolenic acid (ALA), which can contribute to the fight against cancer and enhance brain function; but what your dog’s body really runs on is eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Although your dog can convert some of the ALA into EPA and DHA, it’s not enough to support the body’s entire requirement. Supplying EPA and DHA as part of the diet, by including fish or meat from grass-fed animals, is far better in reducing inflammation and furthering cognitive development. Such foods as mackerel can provide a healthy dose of EPA and DHA when fed as part of your dog’s diet two or three times a week.

Whenever possible, purchase mackerel without such additives as sugar and monosodium glutamate, a flavor enhancer that overstimulates neurotransmitters in the brain. Mackerel packed in water or tomato sauce is preferable over mackerel packed in oil, because your dog will already be receiving enough fats in his diet.

1 cup of canned mackerel has about 300 calories; equivalent to about ¾ cup of commercial dry food

Replace 10 percent of your dog’s regular meal with the following amounts:

10-lb. dog: 2 tablespoons
20-lb. dog: 3 tablespoons
40-lb. dog: ¼ cup
60-lb. dog: ⅓ cup

Mackerel can be used in place of salmon in salmon cakes for your plate, but it’s also beneficial for your dog and easy to prepare. With a wide variety of vegetables, fruits, and fish rich in omega-3 fatty acids, this meal topper is a must for any dog. Using canned mackerel and chopping the vegetables in a food processor enhances digestibility without your having to cook anything. Don’t worry about those tiny mackerel bones; they’re really soft and will break down even further in the food processor.

1 (15.5-ounce) can mackerel
1 garlic clove
1 medium-size carrot
1 medium -size red bell pepper, seeded
½ cup frozen spinach, thawed
1 medium-size red apple, stemmed and cored
½ cup blueberries

1. Drain and rinse the mackerel.
2. Place the mackerel and garlic in a food processor and process until chopped finely.
3. Roughly chop the vegetables and apple, then add to the food processor.
4. Add the blueberries and pulse five or six times to chop all vegetables finely.

Yield: 5½ cups
