Why are so many of our pets overweight?

When I looked at my appointment book for the day, I thought something must be wrong. Someone who worked in the fitness industry was bringing his cat in to the Tufts Obesity Clinic for Animals. Did he confuse us for a different kind of weight management clinic? Is he looking to get muscle on his cat or maybe kitty protein shakes?

I was utterly surprised when I called for my appointment in the lobby and an athletic man stood up with an almost 20-pound cat! I asked if I could speak bluntly with him. Why does someone who clearly knows a lot about keeping healthy need to bring his cat to a veterinary nutritionist? What would he say if the cat was one of the people he helps to keep fit every day? Our conversation then went something like this

Well, Id tell her, suck it up, buttercup. Do some kitty pushups and no more treats!

Well, I have to ask, then, whats stopping you from doing this with your cat?

With a worried look of guilt on his face, he replied, Well, Dr. Linder, I mean she meows at me

This was the moment I realized that I was treating pet obesity all wrong. I needed to focus less on the pet and more on the relationship between people and their pets. Thats whats literally cutting the lives short of the dogs and cats we love so much.

An obese pet isnt a happy pet

As with humans,obesity in petsis at epidemic proportions. Over half of thedogsandcatsaround the globe battle the bulge.While overweight pets may not face the same social stigma as humans, medical and emotional damage is being done all the same. Obesity in animals can cause complications in almost every system in the body, with conditions ranging fromdiabetestoosteoarthritis.

Owners often say they dont care if their pet is fat theres just more of them to love! Its my job to then let them know theres less time to provide that love. Alandmark lifespan studyshowed Labradors who were 10-20 percent overweight not even obese, which is typically defined as greater than 20 percent lived a median 1.8 years shorter than their trim ideal weight counterparts.

Anotherstudyshows that obesity indeed has emotional consequences for pets. Overweight pets have worse scores in vitality, quality of life, pain and emotional disturbance. However, the good news is those values can improve with weight loss.

Furthermore, humans struggle to succeed even in the best conditions and so do pets.In one study, dogs on a weight-loss program were only successful 63 percent of the time.

Showing love through food

So where exactly is the problem? Are foods too high in calories? Are pets not getting enough exercise? Is it genetics? Or do we just fall for those puppy dog eyes and overfeed them because they have in fact trained us (not the other way around!)? From my experience at the pet obesity clinic, I can tell you its a bit of all of the above.

It seems veterinarians and pet owners may be a little behind the curve compared to our human counterparts.Studies showthat it doesnt really matter what approach to weight loss most humans take as long as they stick to it. But many in veterinary medicine focus more on traditional diet and exercise plans, and less on adherence or the reason these pets may have become obese to begin with. (This should be easy, right? The dogs arent opening the fridge door themselves!)

However, the field is starting to understand that pet obesity is much more about the human-animal bond than the food bowl. In 2014, I worked among a group of fellow pet obesity experts organized by the American Animal Hospital Association to publishnew weight management guidelines, recognizing that the human-animal bond needs to be addressed. Is the pet owner ready to make changes and overcome challenges that might slow down their pets weight loss?

One interesting editorial reviewcompared parenting styles to pet ownership. As pet owners, we treat our cats and dogs more like family members. Theres a deeper emotional and psychological bond that was not as common when the family dog was just the family dog. If vets can spot an overindulgent pet parent, perhaps we can help them develop strategies to avoid expressing love through food.

A healthier relationship

Managing obesity in pets will require veterinarians, physicians and psychologiststo work together.

Many veterinary schools and hospitals now employ social workers who help veterinarians understand the social aspect of the human-animal bond and how it impacts the pets care. For example, a dog owner who has lost a spouse and shares an ice cream treat every night with their dog may be trying to replace a tradition they used to cherish with their significant other. A social worker with a psychology background could help prepare a plan that respects the owners bond with their pet without negatively impacting the pets health.

At our obesity clinic at Tufts, physicians, nutritionists and veterinarians are working together to develop joint pet and pet owner weight-loss programs. We want to put together a healthy physical activity program, so pet owners and their dogs can both improve their health and strengthen their bond. We also createda pet owner education websitewith additional strategies for weight loss and pet nutrition.

Programs that strengthen and support the human-animal bondwithout adding calories will be critical to preserve the loving relationship that is the reason why we adopt our pets, but also keep us from literally loving them to death by overfeeding. Hopefully, we can start to chip away at the notion that food is love for our pets.

Obesity in Dogs: A Major Health Threat Hiding in Plain Sight

This Is a Paid Advertisement for The Farmers Dog

Theres a weight problem in America and it isnt just affecting humans.

The most recent statistics classify the majority of dogs in the U.S.56%as overweight or obese. While that makes obesity a major health crisis for dogs, its a problem thats often overlooked, as many pet owners may not even realize their pets are overweight.

I see people coming in constantly with 90-pound Labs and they say, she looks great, says Dr. Ernie Ward, DVM, CVFT, and founder of theAssociation for Pet Obesity Prevention(APOP). Well, actually, that dog is 15 pounds overweight. But weve normalized it. This kind of dog embodies what APOP has called the fat pet gapthe misalignment between what we think a dog should look like and what a healthy body composition should really be.

Obesity in dogs comes with significant consequences. In fact, Ward and other vets call it our pets biggest health threat. And its not an isolated issue; obesity is linked to a whole raft of health problems including arthritis, chronic kidney disease, bladder/urinary tract disease, liver disease, low thyroid hormone production, diabetes, heart failure, high blood pressure, and cancer. We think its very important that people understand this isnt just a cosmetic issue, says Dr. Ward. There is a physiological consequence to this.

A slimmer margin of error

While obesity is loosely defined as 30% above ideal body weight (there is no universally accepted definition forpets), veterinary experts say just being overweight impacts pet health. And thats one of the challenges in addressing this issuemany pet owners may simply not realize thereisan issue.

You look at your dog and it seems healthy and its active and doesnt have any apparent health issues, says Ward. So you say, its normal, and by extension its morphology, or its size, is normal. But the problem is that we often dont know what what normal is when it comes to dogs, so we project our own human-centric perspective. In human terms, we think we just need to drop five pounds, says Ward. Well, the amount of physiological impact of a few pounds is much, much greater and more concentrated in pets than in people. Five pounds on a cat is catastrophic. Five pounds on a Lab is significant. We think a few pounds off my Lab; what could the consequence of that be..? But the consequences are that Labs hips are deteriorating, its causing damage to the kidneys, its probably causing high blood pressure which is causing a constellation of problems, and its increasing cancer risk.

Dr. Carol Osborne, an integrative veterinarian at Chagrin Falls Pet Clinic in Ohio, echoes the fact that a dog doesnt have to be clinically obese to experience health consequences. Being just 10% overweight decreases a dogs lifespan by one-third and predisposes him to heart, kidney and liver disease as well as diabetes, arthritis,and cancer, she says.

Osborne says that adipose tissue (aka fat) is filled with blood vessels, and the added rich blood creates inflammation. This all creates an environment attractive to cancer cells and increases a dogs risk of developing the disease, she says.

Cancer is the number one killer of dogs today, says Osborne.

And, for some smaller breeds, extra pounds make a huge difference. Three extra pounds for canines in the toy category is the equivalent of gaining approximately 30 pounds for you or me, she says.

Holistic veterinarian and researcher Dr. Jean Dodds, of Hemopet veterinary center in California, says the health effects of having even a marginally overweight dog include reduced energy with resultant less exercise, easy keeper (gains weight on small amounts of food), skin and hair coat conditions, and irregular female reproductive cycles, if intact.

Conversely, obese dogs may benefit from even just slight weight loss. According to aclinical trial published in 2010,obese dogs with osteoarthritis showed a significant decrease in lameness from weight loss starting at 6.10%.

Another study,published in the Journal of Veterinary Internal Medicine in 2018 found that being overweight was associated with a shorter lifespan in the 12 dog breeds studied. The estimated reduction in lifespan for the overweight group was up to two-and-a-half years.

We look at a dog with obesity and if a dog loses as little as 6% body weightthats six pounds on a 100-pound Retrieverit makes a difference, says Ward. It doesnt take a lot of weight loss to make the pet feel better. I really try to emphasize that when Im talking to (pet owners) because its a quality of life issue as much as a longevity and disease-prevention issue.

Osborne says shes seen this quality of life improvement from weight loss time and again. One of her clients came in with a two-year-old male Pomeranian named Smokey that weighed in at 45 pounds. When he first visited, the dog already had one cranial cruciate ligament (CCL) surgery on a hind leg and was about to have a second. Osborne changed his dietwhich involved stopping the dry kibble and replacing it with chicken and fresh vegetables.

At this point he is down to 22 pounds, she says. He acts, feels and looks like a puppy instead of sleeping under the kitchen table most of the day and barely moving at all. Hes running around the house, ready to play and having a ball. And he wont need another surgery after all.

Rewriting your dogs future

For pet owners with dogs who are not obese and who arent showing obvious health symptoms, the concern may not seem as pressing. But Ward warns against not taking action when you can.

I see too often a 10-year-old Lab mix and suddenly they cant get into the car because of crippling hip arthritis caused by obesity, he says. But if you can rewind the tape, you dont have the years of cumulative damage. (Obesity) is a slow and insidious and silent killer, and people may know its happening, but they dont take action until theres a crisis. I say that nobody treats obesity until theres a catastrophe. And when its catastrophic, you may not recover.

A guide for dog owners: How to assess your dogs weight

The question remains: How can pet owners determine the ideal weight for their dogs?

The rib testOsborne says it begins with keeping regular track of your dogs body condition. She recommended the rib test.

Stand behind your dog, gently run your hands along either side of the rib cage, she says. You should be able to easily feel, but not see each rib, and your dog should have a waist or a tucked up area in front of the hind legs. If you can pinch more than an inch and/or your dog has lost his waist, its probably time to think about reducing.

The standing testWard opts for another method. I recommend you do the standing test. Look at the dog from the sidelean down and look from the sideand see [if] their abdomen or stomach is sagging, he says. Then I look from the top: From standing I should see an hourglass indentation in front of the hips. You should see the chest extend out and the waist tapers in making an hourglass.

While dogs vary widely in body shape and volume of hair and fur, Ward says this test should work for 95% of dogs (he notes that exceptions include English Bulldogs and Pugs).

Food matters most

Many vets agree that weight loss begins and ends at the food bowl for dogs and cats. Based on available literature and experience, Ward breaks down the weight-loss math this way: 60-70% diet and 30-40% exercise.

So, knowing exactly how much to feed your dog becomes key. Like many experts, Ward cautions against using the guidelines on most commercial dry dog food packages to determine how much youre feeding. The parameters, which are based on adult dogs for all life stages, are far too broad to accommodate every dogs needs. For example, Ward says, spaying or neutering a dog reduces their energy requirement by 20-30%. So already, if youre feeding according to guidelines youre overfeeding a pet who is spayed or neutered, he says. I see so many pet owners say Im feeding exactly what they say on the bag, and its like no, thats too much.

Its a good idea to work with your vet to assess your dogs body condition, muscle condition, lifestyle and any concurrent medical conditions and determine how many calories you should be feeding.

You can also consult the tools available online(including on APOPs site)which provide a good estimate of weight ranges and caloric needs by breed and size.

As to food quality, Osborne recommends fresh food including lean protein like chicken, turkey, fish, eggs and tofu, and fiber through fresh vegetables such as Brussels sprouts, broccoli, cauliflower, kale, cabbage and spinach.

While some dog owners hesitate around the idea of feeding people food, this kind of real, fresh food is more nutrient-dense, and more bioavailable than dried, processed food. Those planning to prepare fresh food at home for any length of time should be sure to consult their vet to ensure meals are correctly balanced and contain the necessary vitamins and nutrients.Subscribing to a fresh-food plan makes it easier, and safer, to feed nutritionally balanced meals.

While food is the biggest factor, pet owners should also plan to exercise dogs for a minimum of 20 minutes, twice a day. And be careful with snacks. You can use fresh veggies as healthy treats and avoid processed mystery-ingredient treats and things like pig ears, and bully sticks.

If you dont eat it, neither should your dog, Osborne says.
