Fats are the major source of energy for dogs, the energy they supply is a more concentrated source (2.5 times) than either protein or carbohydrates. Not only do they supply energy but they also help keep skin and coat healthy, and foot pads supple. Nutritionally, fatty acids aid in the absorption of vitamins because they transport fat-soluble vitamins (A, D, K and E) into the body from the intestine. They also play a role in cell structure and function, including vision and learning abilities. Plus, they make food, both manufactured or homemade, tastier and more palatable.
Fatty acids are a specific type of polyunsaturated fat and are classified into omega-3s or omega-6s. Essential fatty acids (EFAs) are those that the body cannot make for itself, and needs to be supplied daily in the diet, hence they are considered to be essential (this essential status is species-specific). For dogs, the EFAs are omega-3 and omega-6 acids, which are required for them to thrive. In other words, if a body (animal or human) does not receive sufficient amounts of EFAs, critical body functions can be severely disrupted.
While both are important to a diet, it is thought by many nutritionists that commercial pet food (similar to commercial human food) contains too many omega-6s and not enough of the “good fat”, omega-3s. Omega-6s can be found in meat products, egg yolks, whole grains and vegetable oils, while the best source for omega-3s for dogs is cold water fish. Fish oil provides the long-chain omega-3s (EPA and DHA), that are used for metabolism. Another complication is that fatty acids are very unstable and fragile, and tend to oxidize very quickly. They are easily destroyed by heat, light, and oxygen, thus they break down during processing and storage. It is important to note that the only way you can assure that your dog is getting sufficient amounts of EFAs is to either provide fish, such as mackerel, sardines, tuna, salmon, etc., in their diets or add an EFA supplement yourself. If using a supplement, ideally it should be guaranteed-fresh source packaged in an oxygen-free container, such as soft gel capsules that prohibit air from contacting the oil.
Composition and sources of Omega-3 fatty acids:
- EPA (Eicosapentaenoic acid) cold water fish and their oil.
- DHA (Docosahexaenoic acid) cold water fish and their oil, eggs from chickens fed omega-3.
- ALA (Alpha-linolenic acid) found in flaxseed oil, canola, soy beans, navy or kidney beans and walnut oils, plus green leafy veggies.
It is important to note that, unlike humans, dogs cannot convert ALA to the all-important EPA and DHA, so plant oils are not an ideal source of omega-3s for them. ALA from plant foods are often the primary sources of omega-3 found in dog food. While they are still important, this does mean that your dog’s diet may be lacking in EPA and DHA, causing them to miss out on certain health benefits.
Composition and sources of Omega-6 fatty acids:
- LA (Linoleic acid) that can be found in corn, canola, safflower, sunflower oils, whole grain and body fat of poultry.
- GLA (Gamma linolenic acid) in black current seed oil, borage oil and evening primrose oil.
- AA (Arachidonice acid) found in the body fat of poultry, lean meat, egg yolks, some fish oils.
- DGLA (Dihomo-gamma-linolenic acid) found in organ meats.
Benefits of Omega-3s:
As many veterinarians, including Karen Becker, DVM, have noted, “omega-3s have tremendous potential to positively impact your pet’s health.” Here’s a list of what omega-3s contribute to a dog’s health and vitality:
- Support normal neural development, cardiovascular and immune systems, healthy reproduction, and skin and coat health.
- Therapeutic benefits and aid in managing chronic inflammatory disorders, like colitis, obesity, inflammatory bowel disease, joint pain due to arthritis and allergic skin problems.
- DHA is important for development of a healthy nervous system and proper development of the retina and visual cortex in fetuses and newborn puppies.
- Manage stress and improvement of brain health and cognitive functioning, especially in senior dogs.
- Support skin and coat health and relieve dry and itchy skin.
- Omega-3s fatty acids have been shown to slow the development and metastasis of certain cancers, while omega-6s have been shown to stimulate tumor development.
- Fish oils have been shown to decrease the levels of triglycerides and cholesterol in the blood.Not All Fish Oil Is Created Equally
With the rising popularity of fish oil for both the human and canine health, there are many different manufacturers making a variety of claims. So when selecting which omega-3 oil to purchase you need to consider a few factors including, purity, freshness, potency, bio-availability and sustainability.
Purity: The oil must meet international standards for heavy metals, PCBs, dioxins and other contaminants. You need to check with the manufacturer’s Certificate of Analysis (CoA) to receive third-party verification. Many oils come from areas of the ocean that are heavily trafficked and/or polluted by deep sea oil rigs. Make sure you know what part of the world the fish was caught.
Freshness: EFAs are susceptible to oxidation, which turns them rancid. Look for verification about the freshness from the CoA, and for companies that use smaller vessels. Ask how the fish is kept fresh once it is caught, and how long does it take from the “catch” to the processing plant. The product should be available in an oxygen-free container, such as soft gel capsules that prohibit air from contacting the oil. Freshness is measured by oxidation as shown in the CoA’s anisidine and peroxide values, that should be less than 5 meq/kg.
Potency: The oil must contain DHA and EPA. DHA provides most benefits to dogs, so it should exceed the levels of EPA.
Bio-Availability: The oil must be in a natural form not a synthetic triglyceride which many fish oils are.
Sustainability: Many fish oils are made from fish that are endangered. Choose products made from fish that are certified by organizations such as the Global Organization for EPA and DHA Omega-3s (GOED).
It’s important to look for or request a Certificate of Analysis (CoA) from the maker before you buy a fish oil product and if you have any questions, the company should be available to address those in a timely manner.
Omega-3s and omega-6s are indeed essential fatty acids, not only because they need to be added to a diet, but because they are essential to overall health. However, as they also add calories, attention needs to be given to the overall caloric count that is provided to a dog in both their food and supplementation. Consultation with your veterinarian is also recommended.

As the mom of two young children, I’m always checking the weather forecast. Jacket or sweater? Rain boots or sneakers? As a veterinarian with the American Animal Hospital Association (AAHA), I rely on a different forecast, the Companion Animal Parasite Council findings published by my veterinary colleagues, which tracks the intensity of pet diseases from year to year. Here’s what to expect for the remainder of 2016.HEARTWORM DISEASE FORECAST: STORMY
Veterinarians anticipate a rise in heartworm disease because of the unusual weather pattern created by El Niño. The warmer temperatures and wetter conditions create an ideal breeding environment for mosquitoes. When an infected mosquito bites a dog, the larvae are injected into the dog’s skin. They migrate through the body, finding their way to the large blood vessels of the heart and lungs. There, they mature to the size of cooked spaghetti. These tangled masses of worms can cause heart failure, and even death, if not treated early.
Expect to see cases skyrocket in:
Heartworm disease is prevalent in the Lower Mississippi River region and this year it’s expected to spread to:
All dogs need to be protected from heartworms, even those who rarely venture outside. The one mosquito that flies through your open window and bites your dog just might be infected with heartworm larvae. Preventives are available in the form of pills, topical liquids and injections. All kill the larvae once they enter the bloodstream. The AAHA recommends year-round heartworm prevention.TICK-BORNE DISEASE FORECAST: PARTIALLY CLOUDY
An infected tick can spread a number of life-threatening diseases when it bites a dog. The most common are Lyme, anaplasmosis and ehrlichiosis, and their prevalence varies by region. Some dogs with Lyme disease will run a high fever, experience painful joints and exhibit swollen lymph nodes. Others will present no signs at all. Untreated infections can lead to kidney failure and death.
In regions where Lyme has been living comfortably for years, the incidence is expected to rise. These regions include:
Recently, the disease has spread to:
These states may have a higher-than-average occurrence the rest of the year.
Historically, Lyme has thrived in New England, but, oddly enough, the incidence there is expected to fall below normal this year, perhaps because more owners are vaccinating their dogs.
If you live in an area where ticks are abundant, take precautions to keep your dogs safe. Your veterinarian will prescribe a tick preventive in the form of pills, topical liquids or collars. In areas where Lyme disease is prevalent, she may recommend vaccination.
Anaplasmosis causes disruptions in blood clotting, which results in bruising, internal bleeding and nosebleeds. Signs of Lyme disease also present in anaplasmosis.
Anaplasmosis shows moderate to high activity in:
Ehrlichiosis displays signs similar to both Lyme and anaplasmosis along with eye, liver and spleen infections. Above-normal incidence of ehrlichiosis is expected in:
Just like the human flu, canine influenza is spread by one infected dog sneezing or coughing on another. Two strains of canine influenza are present in the U.S. H3N8 has been here for years, but a vaccine has kept it at bay. A new Asian strain, H3N2, hit Chicago last spring, causing a local epidemic; dogs didn’t have a natural immunity to the strain and there was no vaccine. Since then, H3N2 has infected more than 1,000 dogs in more than 25 states. Fortunately, H3N2 vaccines were developed not long after the outbreak, which likely curbed the spread. It’s difficult to predict how the flu season will play out for the rest of the year. With so many dogs on the move with their owners, and not all of them protected by vaccines for the new strain, the disease could spread quickly. If you plan to travel with your dog, visit your veterinarian for a vaccine protocol.

Ah, summer—a season for rambles, picnics and water fun. Longer days and warm weather inspire us to get ourselves and our dogs outside to soak up some sun (judiciously) and get some exercise.
Maintaining our dogs’ grooming routines is also important. It’s not all about looking good, though that’s certainly one motivator; it’s also about keeping a close eye on the condition of our dogs’ skin, ears and nails, solving small problems before they become big ones.
While some breeds require the services of a professional groomer, all dogs benefit from a good brushing, and you don’t have to be a pro to do that. A dog’s best friend is a tool appropriate for his coat type, one that strips out loose hair so air can circulate against his skin. Regular and thorough brushing also prevents mats, which are not only painful but also trap heat and moisture and can result in skin infections.
However, experts tell us to resist the urge to shave down our dogs, particularly those with double coats, who can be quite comfortable as long as those coats are well cared for. Whatever its length and composition, a dog’s coat provides built-in climate control as well as a first line of defense against sunburn, twigs and stickers, among other things.
This is also the time of year to be particularly vigilant about ticks and fleas. The former can carry disease and the latter can quickly set up housekeeping on your dog—and in your house—if not managed. Another reason to be conscientious about wielding the brush, rake or comb of your choice. While your dog may or may not agree, adding an extra bath or two is also a good summer strategy. Brush before and after, choose a shampoo that’s a good match for his skin and coat type (or make your own), lather once and rinse well.
Check your dog’s ears regularly, particularly if swimming is on his play list. Dogs whose ears fold over are prone to ear infections, which wet ears promote. Some groomers pluck hair from a dog’s ear canal, but vets advise against this, as the hair pores then secrete extra serum, providing another excellent medium for infection. After your dog takes a dip, wipe the inside earflap gently with a cotton ball; if your vet says it’s okay, you can also use drops that contain a drying agent. According to the Dog Owner’s Home Veterinary Handbook, a drop of white vinegar will also help prevent “swimmer’s ear.”
And in the “of course” category, continue to brush your dog’s pearly whites and pay attention to his paws. Check between his toes for ticks, foxtails, brambles or other debris, and trim his nails.
None of this is rocket science, just good old-fashioned conscientiousness. And the payoff is so worth it: a dog who feels good and smells good, and far fewer fur-bunnies rolling across the floor and lurking under the couch!

This summer’s routine insect-prevention strategies are taking on a new urgency as public health experts warn that certain parts of the U.S. may experience outbreaks of the Zika virus, which has been linked to birth defects in Latin America.
As you protect yourself from any and all mosquitos this summer, don’t hurt your dog in the process!
The Centers for Disease Control recommends people use insect repellents that use of these ingredients:
Unfortunately, DEET can be poisonous to your dog. Ingesting it can cause your dog to have stomach problems, conjunctivitis, breathing difficulties and seizures.
So using it as a spray on your dog’s coat is a big no-no. And be careful that they don’t lick it off of you or get into any bug-spray cans that may have been left in the back yard or in your hiking backpacks.
Signs of possible DEET ingestion include drooling, wobbly gait, vomiting and loss of appetite, according to the ASPCA Animal Poison Control Center, which reports getting calls every summer involving dogs hurt by DEET exposure. If you think your dog has been exposed to DEET, take her to the vet immediately.
For dog people worried that their dog may get her nose into some DEET, good alternatives for mosquito protection are oils from lemon eucalyptus and cedar, which can be used as an insect repellent for people and pets alike.
CDC researchers say there have been no signs that dogs have been affected by Zika or that they act as carriers for the virus. In fact, the mosquitoes that carry the Zika virus seek out humans to bite on rather than animals.
Despite the lack of a direct link to Zika, safeguarding your dog against mosquito bites is still critical.
A bite from one mosquito bite infected with the heartworm larvae will give your dog heartworm disease, which can be fatal. With one bite, the larvae can be deposited into your dog. That larvae can grow to cause severe injury to the dog’s lungs, major arteries and heart, harming your dog’s quality of life and potentially her lifespan.
For full protection against mosquitos and heartworms, ask your veterinarian about products that can repel fleas, ticks and mosquitoes. There are also some products available that do double duty by offering heartworm prevention.
Frequently, it is difficult to tell if your dog has been bitten by a mosquito. One telltale sign is scratching. Some dogs will have an allergic reaction and the bitten areas will swell. In most cases, however, all you will see at the spot of the bite is a bump.
To treat the bite, wash the affected area with a mild soap and warm water and apply a topical antibacterial cream. If the bite gets worse or does not improve over the next few days, take your dog to the vet for an examination.

Researchers Richard G. Lea and associates published on Aug 9th, 2016, a report entitled Environmental chemicals impact dog semen quality in vitro and may be associated with a temporal decline in sperm motility and increased cryptorchidism. (In Nature, Scientific Reports 6, Article number: 31281 (2016) doi:10.1038/srep31281). Against the background of declining semen quality and rising incidence of undescended testes (Cryptorchidism) in humans associated with exposure to environmental chemicals (ECs) during development they report that “a population of breeding dogs exhibit a 26 year (1988–2014) decline in sperm quality and a concurrent increased incidence of cryptorchidism in male offspring (1995–2014). A decline in the number of males born relative to the number of females was also observed. ECs, including diethylhexyl phthalate (DEHP) and polychlorinated bisphenol 153 (PCB153), were detected in adult dog testes and commercial dog foods at concentrations reported to perturb reproductive function in other species”.
Estrogen-mimicking, endocrine-disrupting chemicals have become virtually ubiquitous in many of the foods we consume, some of which, along with their byproducts, are included in most manufactured pet foods; in the can-linings of moist, and in plastic bagging and wrapping of dry and semi-moist foods. Plastic may also be processed into the manufactured food along with discarded meats, packaging and all.
Food wrappers and other industrial and commercial products from firefighting foam to water-repellant clothing contain poly-and perfluoroalkyl substances, or PFAS, detected in drinking water and having endocrine disrupting and carcinogenic properties.
Dioxins, predominantly released as byproducts of human activities such as incineration and fuel combustion, are a most potent class of carcinogens and endocrine disruptors. They are ubiquitous in the environment, and from the soil and vegetation undergo bioaccumulation in the fat (tallow) of cattle, and sea foods, especially farmed salmon, which are common pet food ingredients. Their adverse impact on wildlife reproduction and sexual development in several aquatic and terrestrial species has been well documented.
Other estrogen-mimicking and endocrine disrupting contaminants of pet (and human) foods include glyphosate and other herbicide residues in corn and other cereals along with phytoestrogens in soy products especially in GMO soy, a widely used pet food ingredient.
Aflatoxin B1—yet another endocrine disruptor-from the mold on corn and other cereals, is often found in dry dog foods which are recalled too late to save many dogs from acute toxicity and death. Aflatoxins, dioxins and other endocrine disruptors, estrogen mimics, carcinogens and obesogens have harmful consequences in extremely low concentrations in the diet over an extended time period with possible synergism operating where one contaminant increases the toxicity of one or more others; and prenatal, epigenetic, developmental effects on the offspring of exposed parents.

Dog's Life: Lifestyle
While beaches are a great place for pets to cool off, get some exercise and play, there are some important precautions to take to keep pets safe, even at beaches designated specifically for dogs. Included below are five of the top beach dangers for dogs, along with tips for keeping your dog safe from Trupanion.
1. Sun burns – You may not realize it, but even dogs can get sun burns. Their noses, bellies, and areas with particularly thinner fur are susceptible to the sun’s hot rays so it’s important to protect your pooch. Provide shade with a beach umbrella and consider dog-friendly sunscreen. (Many sunscreens made for humans can be toxic to dogs. Be sure to avoid sunscreen with mineral Zinc Oxide which can harmful to your pup.) Also consider looking into doggy sun goggles to protect your pooch’s eyes from harmful rays.
2. Salt water – Your pup may be inclined to lap up the salty ocean water if he’s thirsty, but the salt, bacteria and parasites in the water can make them sick. Prevent your dog from drinking salt water by providing plenty of fresh water. It’s also important not to let the salt water dry on their fur since it can irritate their skin. Be sure to give your pup a good rinse off with fresh water when he’s done swimming.
3. Seaweed and sea creatures – While exploring the beach you may come across washed up sea life and other items. Keep a close eye on your dog to prevent him from rolling in or eating anything that could make him sick. Some areas also have higher danger of sea creatures like jellyfish so be sure to keep a close watch on the surrounding waters to keep your pet safe.
4. Hot sand – If the sand is too hot for you to walk barefoot, then it’s too hot for your pup’s paw pads. Save your beach trip for a cooler day or go in the early morning or late evening to avoid the heat.
5. Big waves – Your dog may be a strong swimmer, but large rolling waves can be very dangerous. You might choose to keep your dog on a leash so that he can’t go out too far, or purchase a dog life jacket in case he gets too tired swimming.

Toxic chemicals also found in dog food
A long-term study conducted in Britain has found that male dogs are losing fertility, and that exposure to environmental chemicals (ECs) that have leached into the environment may be to blame.
The dogs—Labradors, Border Collies, German Shepherds and Golden Retrievers bred to aid the disabled—made an ideal group to explore the larger question of a decline in human semen quality that has been occurring since long before this study.
This twenty-six year long study, 1998-2014, was conducted by Richard Lea and colleagues at Nottingham University’s school of veterinary medicine. They collected annual samples of semen from dozens of dogs, all from the same breeding program, all healthy and well cared for. Each year, the same problem recurred; a 2.4 percent dip in sperm motility, that is the ability to swim in a straight line. In addition to monitoring semen quality, they analyzed health records, finding an increase in cryptorchidism, a condition in which the testicles fail to extend normally to the scrotum. Over the same years, fewer male pups were born than females, also there was an increase in fetal and prenatal female mortality.
And, lurking in the samples of semen and testicles of dogs obtained from neutering, it found ECs—chemicals that tamper with hormones. The chemicals include polychlorinated bisphenol (PCB), a compound banned in 1977, and diethylhexyl phthalate (DEHP). PCBs don’t readily break down while phthalates are common in a wide number of products, from cosmetics to detergent. Both chemicals are associated with fertility issues and birth defects.
In human babies, exposure to chemicals has been linked to faulty development of semen quality and cryptorchidism. According to the study, such reproductive problems often cluster in geographical areas, and so are suspected of having a common cause; exposure to hormone-disrupting chemicals is “thought to be the initiator.” To explore the same possibility in dogs, chemicals were measured in canine testes and semen taken from the same geographical area where the study took place.
Both chemicals “perturbed sperm viability, motility and DNA integrity in vitro.” The researchers concluded that the direct effects of chemicals on sperm “may contribute to the decline in canine semen quality” that parallels that in humans.
“Why the dog?” said Dr. Lea. “Apart from the fact that it is a great population of animals to work with, dogs live in our homes, they sometimes eat the same food, they are exposed to the same environmental contaminants that we are, so the underlying hypothesis is that the dog is really a type of sentinel for human exposure.”
The same ECs were found in a range of commercially available dog foods. DEHP and PCB153, “were detected in adult dog testes and commercial dog foods at concentrations reported to perturb reproductive function in other species.”
While the brands were not named, they are reported to be both wet and dry forms sold worldwide. The scientists don’t know how the chemicals made it into the food, but since they are not deliberate additives, they may have leached from the packaging or processing sources.
These overall findings are troubling, but they also noted that: “Amongst the dry dog food samples, one sample designed for puppies (1 to 24 months of age) had higher concentrations … relative to the other samples tested.”
Plus, while the researchers cannot say the dog food is a direct source of the ECs, the New York Times reports that "Dr. Lea said it was probably a major one."
What is known is that the chemicals wound up in dog’s testicles, where they messed with sperm motility and viability. “This may be a way by which environmental chemicals directly affect male fertility.”
While the dogs in the study were still able to reproduce, it’s hardly reassuring that, once more, the dogs who share our homes also share our diseases, unwittingly, acting as the “canary in the mine” for us.

Not surprisingly, a study published July 29, 2016 found that the English Bulldog no longer retains enough genetic diversity to correct life-threatening physical and genomic abnormalities. This means breeders cannot use the established population of purebred dogs to reverse the trend in extreme and painful exaggerations such as crippling dwarfism and respiratory deformities - traits that uninformed pet-owners find appealing.
In the early 1800s Bulldogs were trained for bull-baiting, a particularly cruel and vicious sport. In 1835 the Royal Society for the Prevention of Cruelty to Animals convinced Parliament to enact the first animal cruelty law for the protection of domestic animals, including outlawing bull baiting.
As such, the Bulldog had outlived its usefulness. Like the pre-19th century Wolfhound that disappeared with the eradication of wolves in the British Isles, and the Tumbler whose demise was the invention of hunting firearms, the Bulldog was destined for extinction.
English Bulldog from 1890
But it was not to be. Beginning about 1840, the Victorian dog fancy's unabashed sentimentality was a catalyst for saving even the most formidable working breeds from their inevitable demise. Like many others, such as the Dachshund and Mastiff, Bulldogs went from working hard to hardly working.
Utility dogs were "refined" and transformed to fill jobs they weren't originally bred for - as show dogs and companions. Altered physical and behavior characteristics along with decreased levels of aggression were more compatible for their augmented duties as house pets.
English Bulldogs from 1920s
Beginning in the late 1890s, Bulldog breeders (and other breeders as well) selected small groups of genes from a diverse genome and created new breed-types. They were in effect increasing the odds that genetic anomalies would more likely be expressed to bring out exaggerated traits, like the Bulldog's baby-like face, corkscrew tail and affable personality.
As "desirable" aesthetic traits were selected for, other genetic variants including beneficial genes that contribute to overall health were eliminated from the gene pool, never to be reclaimed.
In the last few decades the most exaggerated traits in the Bulldog - the extreme brachycephalic skull and deformed skeleton- have become increasingly pronounced because naive consumers want that type of dog and consequently that's what many breeders select for.
Driven by economics, fashion, and uninformed decisions, breeders and buyers either ignore or are unaware of the genetic problems that have spread throughout the population.
The demise of the breed may not be a good thing for Bulldog-lovers, but it will thankfully put an end to the malformed and painfully crippled modern Bulldog we recognize today.
The good news is that some breeders are intent on bringing back the "Olde-Fashioned-Bulldogge".

Study finds these elective surgeries influence perceptions of dog personality
Just when you think you know a thing or two about dogs, there I was in Italy a few weeks ago after the Canine Science Forum, looking at a dog on the street and exclaiming, “Who the heck is that!”
“A Doberman!” offered my good friend and Do You Believe in Dog? colleague, Mia Cobb.
“Really?” I said in disbelief. Because it was true. I’d never seen a dog that looked like that. Every Doberman I’ve seen has looked like this:
Dog with docked tail and cropped ears. Credit: Figure 2. Mills et al (2016)
Not like this:
Same dog, but natural. Credit: Figure 2. Mills et al (2016)
The bottom image, of course, is the Doberman in her natural form. A dog born from two Dobermans will grow up to look like the bottom image. But the Dobermans I’ve seen have had two post-birth surgeries; their tails are shortened or docked, and the floppy part of each ear is cut, followed by the ears being taped to a hard surface forcing them to stand upright in a way they normally would not.
These cosmetic surgeries (also referred to by veterinarians as elective surgeries) are built into breed standards — see an example from theAmerican Kennel Club. Which is to say that a Doberman puppy born from two Doberman parents does not meet his or her own breed standard.
In some countries, dog surgical procedures for cosmetic purposes are restricted or banned, but in others, the practices are rampant. For example, cosmetic tail-docking is banned throughout Australia and in numerous parts of Europe, which is why I saw my first natural Doberman in Italy. In North America, things look a bit different. The American Veterinary Medical Association (AVMA) and the Canadian Veterinary Medical Association (CVMA) oppose these procedures, with the AVMA stating that these procedures "are not medically indicated nor of benefit to the patient," and "these procedures cause pain and distress, and, as with all surgical procedures, are accompanied by inherent risks of anesthesia, blood loss, and infection." Even so, restrictions are rare. As of 2014, only two states, Maryland and Pennsylvania, have any restrictions on tail-docking, focusing on the dog’s age at the time of surgery and the use of anesthesia. Only nine states regulate ear cropping.
In addition to welfare concerns associated with docking and cropping, the surgeries could affect dog social communication. Numerous studies find that tails are (gasp) useful and meaningful in dog-dog communication (more formally known as intraspecific communication, or communication between members of the same species). Even Charles Darwin recognized that tail up has a different meaning than tail down, and dogs attend to long tails better than short ones. The side of the body that a tail wags can even be informative to another dog: a dog seen wagging more to his right-side would be perceived more positively than a dog wagging more to his left. A stump is less informative.
The communicative function of dog tails has received oodles of attention (see additional readings at the end of the post), and I’m going to focus on a new issue raised last month by Marina von Keyserlingk and colleagues at the University of British Columbia in Vancouver, Canada. Their open access article in PLoS One finds that these appearance-altering procedures are not meaningless; they affect how dogs are perceived, independent of the dog's actual behavior or personality.
Study participants, United States residents participating via Amazon’s Mechanical Turk (MTurk), saw images of four dog breeds that commonly have their tails docked and ears cropped: the Doberman Pincher, Miniature Schnauzer, Boxer, and Brussels Griffon. The first three are in the top 20 of registered breeds, and the Brussels Griffon, while not as popular, was selected to include a small breed in the study.
Participants saw two different images of the same dog breed, one in the natural state (long tail and unaltered ears) and one modified (docked tail and cropped ears). They were told that the dogs were siblings and asked to explain why the ears and tails looked different.
Fifty-eight percent of participants correctly identified that “some dog breeds have part of their ears and tails surgically removed after they are born.” Dog owners were more likely to answer correctly than non-owners.
On the other hand, 40% did not know that these dogs are not born with their ears cropped and tails docked. Instead, these participants thought these traits resulted from genetic variation, agreeing with the statement, “individual dogs of the same breed vary in appearance, meaning some will have tails and ears of different shapes and sizes.” Sorry y’all. Not so for the dogs in this study! The tails and ears on the ‘modified’ dog are all us.
But what’s the effect? Another experiment in the study found that these cosmetic surgeries are not meaningless to dogs or people; in fact, these procedures affect how participants perceived dog personality traits. Generally speaking, surgically altered dogs were seen as more aggressive toward people and dogs than natural dogs, and natural dogs were seen as more playful and attractive than their altered counterparts.
But when looking at the four breeds individually, something odd popped out about attractiveness. For the Boxer, Doberman Pinscher, and Miniature Schnauzer, neither the natural or surgically altered dog was considered more attractive. Take the tail off, leave it on, crop those ears, whatever. For those breeds, people were indifferent — one appearance was not viewed as more attractive than the other. Only for the Brussels Griffon was the natural dog considered more attractive than its surgically altered counterpart.
If not all people know that the cropped/docked look is surgically created and don't find these dogs less attractive than their natural counterparts, what incentive is there to reduce these cosmetic surgeries in the companion dog population? Since 2008, the American Veterinary Medical Association has encouraged “the elimination of ear cropping and tail docking from breed standards.” Who is going to stand with them?

This dog running company is great business idea
Like many runners who have lived in Flagstaff, Ariz. Adam Vess is a professional runner. Adam is also, like many people in Flagstaff, a dog person. He found that if he runs 4-6 miles with his dogs Alex and Macy before going to work, they are happier and easier to live with. His business began with the thought, “Could other people use this, too?”
The answer was yes, and Flagstaff Dog Running was born. Now that Vess has moved back to the east coast, there is not anyone in our area offering this service. Vess spent many hours taking dogs out to run on the trails or fire roads around town to keep their joints and the rest of them safe from the dangers of the streets. Dogs were always on leash, and were with him for up to two hours. He ran them long enough that they’re fatigued, but not anywhere near exhaustion. Most dogs are happily tired out in 30-40 minutes, though some dogs need well over an hour to reach that point.
The charge was $25 a session, and $40 for two dogs. They never ran more than two dogs at a time because of safety concerns, and 10-12 miles is the maximum distance he took any dog. That was only for fit dogs who have gradually and safely built up to running such distances.
Adam originally planned to expand his business to exercising dogs at boarding kennels. People boarding their dogs would have been able to request and pay for the running as a special service. The exercise and the opportunity to go on an adventure as well as to have some company would all have enhanced their kennel experience.
If you lived in a town with a dog person who was a professional runner, would you consider hiring that person to exercise your dog? Does anyone in your area offer this service?
