Obesity
With obesity so common among humans, it is no surprise that obesity also plagues companion animals. Not only dogs and cats, but horses, birds and hamsters, often have difficulty staying at an ideal weight. Unfortunately, even moderate obesity can have a serious negative impact on an animal's health, in many cases shortening its lifespan. Multiple areas of the body are affected by excess body fat, including bones, joints and the digestive and respiratory systems.
Reasons for Obesity
Obesity in animals is usually the result of too many ingested calories and too little exercise. Because so many pet owners are at work for a good portion of the pets' waking hours, owners have a tendency to spend more time cuddling and feeding treats to their animals than exercising them. Nonetheless, not all the blame for animal weight gain can be placed on their human companions. Other factors must be considered as possible culprits in animal obesity, including:
- Neutering
- Age
- Breed
- Medications
- Endocrine imbalance
As animals reach and pass middle age, their tendency to put on excess weight increases, often because they become less frisky and less inclined to exercise. Neutered animals are also more likely to add pounds. Certain disease conditions, or medications administered to control those conditions, may cause weight gain as well.
Finally, certain breeds are more prone to excess weight gain than others. Breeds which bear special watching in terms of possible weight gain include large breeds in general and Labrador retrievers, golden retrievers and Newfoundlands in particular. Other, smaller breeds of dogs that also bear watching include cocker spaniels, pugs, bulldogs and Bichons.
Other breeds, usually those for which the ideal body type is considered graceful or athletic, rather than massive and muscular, are more likely to stay trim. These include: whippets, boxers and setters.
Medical Problems and Obesity
The reasons to try to keep your pet at its optimal weight are many and varied. A great many medical issues can be generated or exacerbated by excess weight. These include:
- Diabetes
- Heart disease
- Decreased liver function
- Breathing difficulties
- Arthritis
Once weight-related medical conditions set in, exercising becomes more difficult and a dangerous cycle of inactivity and overeating may develop.
Diagnosis of Obesity
Veterinary checkups should always include a full weight evaluation, Not only should the animal we weighed on a scale, but physically examined by the vet, including a palpation of the ribs, lumbar region, head and tail, with its measurements compared to the breed standard. An animal found to be 10 to 15 percent overweight is usually considered obese.
Treating Obesity
Apart from treating the overweight animal for any underlying medical problems that may be working against its weight loss, the chief method of treating obesity is to restrict food intake and increase activity level.
Weight-loss diets for animals are normally rich in fiber and dietary protein and low in fat. The protein will speed up metabolism and increase the animal's sensation of fullness after a feeding, and the fiber will stimulate its metabolism. All obese animals should be encouraged, sometimes forced, into exercise. Dogs should be taken on extended walks for at least 15 minutes twice a day and enticed into active games like fetch. Cats can also teased into active play with yarn, boxes and balls. Hamsters of ferrets can be coaxed to make use of more complex climbing equipment made for the purpose. Overweight horses can be taken out for more frequent rides.
Follow-up treatment is necessary to achieve and maintain animal weight loss. This should include regular veterinary monitoring of the animal's weight. The doctor may recommend particular commercial foods designed to assist in weight loss and may also make further suggestions about nutrition and exercise.
