Exercise and the Overweight Pet: A Common-Sense Approach

Has your pet ever been fat shamed? Maybe it was a casual dig at the dog park. Or an insensitive remark on social media. It can be easy to underestimate how many extra pounds your pet may be carrying because, frankly, pet obesity has become the new normal. That is why we’re pointing out that tomorrow is National Pet Obesity Awareness Day. Pet obesity is nothing to take lightly!

About 59.5 percent of cats and 55.8 percent of dogs are considered overweight or obese, according to the Association for Pet Obesity Prevention (APOP). Obesity can contribute to diabetes, joint problems such as arthritis, difficulty breathing and even a shorter life span.

If you’ve got a pet who needs to take care of their weight, you’ll likely need to change their diet — including feeding them fewer human food treats. But increasing the exercise is equally important because you want your pet to lose fat while retaining or building muscle mass. How much exercise is healthy? Here are some tips to help your pet drop those unwanted pounds and earn the praise and admiration he or she deserves.

First stop: your veterinary clinic

Your veterinarian will weigh your pet and show you how to objectively determine your pet’s ideal weight. Together, you can make a plan on how to approach your pet’s weight loss. Your veterinarian may recommend a therapeutic weight loss diet or determine the right quantity of your current food to help your pet lose weight while still receiving all the nutrition they need.

The doctor will also check to see if your pet has any underlying conditions, such as hypothyroidism (low thyroid hormone) in dogs, which, when treated, can help with weight loss. He or she will also examine your pet for underlying heart or orthopedic conditions that may impact your pet’s exercise plan.

Gradual weight loss is best

Your pet shouldn’t lose weight too fast. As a general rule, a dog can lose about 1 to 3 percent of their body weight per month, while a cat can lose 0.5 to 2 percent per month, according to APOP. But this may vary depending on your pet’s breed and weight. Overweight cats who lose weight too fast and go off their food are prone to fatty liver disease, a serious and sometimes fatal condition. If your cat doesn’t eat for a day or two, contact your veterinarian.

Begin exercise gradually, too

Your veterinarian will typically recommend short exercise sessions, then gradually extend the length of these sessions as your pet loses weight. For overweight or arthritic dogs, low-impact exercises like walking and swimming are good because they put less stress on the joints than running and jumping. If your pet has arthritis, ask your veterinarian about medications to help your dog exercise pain free.

Start with short walks on flat terrain, gradually extending the walk and adding hills. Let your dog warm up and do their business, then gently increase the speed of your walk so your dog is getting some heart-pounding aerobic exercise. If your dog starts panting too much or lagging behind, that’s your cue to slow down a bit. Dogs that are overweight, especially those that are brachycephalic, or flat-faced, can have trouble breathing and become overheated easily. It’s best to walk these dogs in the cool of the morning or evening.

Depending on your dog’s health status, your veterinarian may recommend an exercise regimen of perhaps 30-minute walks five times a week. Each week, you can gradually increase the amount of aerobic time during the walk. If your dog tolerates that well, you can build up to twice-a-day walks or jogging.

Another alternative is to schedule regular appointments at canine rehabilitation clinics, where they can put your dog through the paces on regular or underwater treadmills. You can even make use of digital pet activity monitors to help monitor your pet’s daily efforts.

Cat fitness

Cats can be slightly more challenging to exercise, but you can start with 5-minute play sessions, chasing a laser pointer or feather toy. A cat tree can encourage your cat to climb and stretch its muscles. Food puzzles make your cat work for their meals and provide mental stimulation. Another alternative is to hide kibble in different parts of the house so your cat has to “hunt” for their meal.

Monitor progress with monthly weigh-ins

Whether you weigh your pet at the veterinary office or on your own scale, it’s important to make sure your pet is making weight-loss progress. Too much or too little weight loss suggests a call to your veterinarian, who can make adjustments in diet or exercise to keep your pet on track.

The Lifestyle of Overweight Dogs: A Sobering Study

People aren’t the only ones who need to worry about a mid-life spare tire. Obesity in dogs is a major problem, too. But it’s not just a matter of letting the collar out a few notches or buying a roomier dog bed — a recent study of chubby middle-aged dogs shows that curbing obesity in dogs could actually add years to their lives.

Less Overweight Dogs = More Years

Researchers examined the medical records of more than 50,700 middle-aged, spayed or neutered dogs, comparing the life spans of overweight pups against their normal-weight counterparts. Published in the Journal of Veterinary Internal Medicine, the study found that dogs with ideal body weights lived up to 2.5 years longer.

The scientists compared 12 purebred breeds — representing five general sizes — including chihuahuas, Pomeranians, shih tzus, dachshunds, Yorkshire terriers, cocker spaniels, beagles, boxers, German shepherds, golden retrievers, Labrador retrievers and pit bull terriers. All overweight dogs, on average, lived shorter life spans than normal-weight dogs, ranging from 2.5 years shorter for Yorkshire terriers to just a few months less for German shepherds.

Overweight Dogs Are A Common Problem

In the United States, approximately 56 percent of dogs and 60 percent of cats are overweight or obese, according to the Association for Pet Obesity Prevention. A dog or cat is considered overweight if it’s 10 to 19 percent heavier than its ideal body weight. When that figure creeps up to 20 percent or more, the pet falls into the obese category.

If you’re not sure what your pet should weigh, ask your veterinarian. These BMI charts for dogs can also help you determine if your pet is perhaps a little too roly-poly.

Extra Pounds, Extra Health Risks for Overweight Dogs

Obesity is considered a chronic inflammatory condition, contributing to changes in insulin resistance, metabolism and appetite control. Those few extra pounds can put your dog at risk of a range of diseases and conditions including cruciate ligament tears, arthritis, diabetes and even certain types of cancer.

Added weight can also contribute to respiratory, heart and kidney problems. Is it any wonder overweight pets may not live as long as leaner dogs and cats? Or that the international veterinary and human medical communities have recommended that obesity be classified as a disease?

Getting an Overweight Dog Back on Track

Helping your pet return to an ideal weight is one of the most loving things you can do to improve his or her health. As with people, it’s a matter of fewer calories in and more calories burned. Here are some simple steps you can take:

1. Talk to your veterinarian to determine what your pet really should weigh.
2. The doctor may recommend a specific diet and the daily amount your pet should be fed. Most weight-loss diets typically provide more protein and fiber and less calories and fats than maintenance diets. Feeding a high-fiber diet can also help your pet feel fuller and less inclined to beg.
3. Avoid the bottomless bowl syndrome. Instead of keeping your pet’s dish full all day, start using a measuring cup to make sure your dog or cat only gets what it needs.
4. Account for snacks. Every rawhide, table scrap and spoonful of peanut butter contains calories. If you can’t resist food treats, opt for healthier, lower calorie snacks such as sliced bananas, green beans or carrots. Make sure everyone in your family is on board with the treat-reduction program.
5. Increase the physical activity. Leash walks, swimming, a game of fetch or even regular play dates at the dog park are fun ways to help your dog work out. If your pet is extremely overweight, talk to your veterinarian about how to gradually increase exercise so your pet doesn’t overdo it at first.
6. Weigh your pet regularly. A healthy goal for your pet is a 1–2 percent reduction in body weight per week.
7. Avoid the yo-yo syndrome. Once your dog loses weight, returning to its couch-surfing days will make it easier for the pounds to creep back. The positive changes you’ve made in terms of food control and exercise need to be a permanent part of your pet’s life.

Granted, weight loss can be a long, slow process. But when you think about it, every small weight loss — even if it’s just a half pound — could mean better health and more time with your dog. And what could be more motivating than that?
