Obesity is a nutritional disease which is defined by an excess of body fat. Animals that are over nourished, lack the ability to exercise, or that have a tendency to retain weight are the most at risk for becoming obese. Obesity can result in serious adverse health effects, such as reducing the lifespan, even if your pet is only moderately obese. Multiple areas of the body are affected by excess body fat, including the bones and joints, the digestive organs, and the organs responsible for breathing capacity.

Obesity is common in pets of all ages, but it usually occurs in middle-aged animals, and generally in those that are between the ages of 5 and 10. Neutered and indoor pets also tend to have a higher risk of becoming obese.


• Weight gain
• Excess body fat
• The inability (or unwillingness) to exercise
• An above-ideal score in a body condition assessment


There are several causes of obesity. It is mostly commonly caused by an imbalance between the energy intake and its usage ie eating more than the animal can possibly burn off during exercise. Obesity also becomes more common in old age because of the normal decrease in a pet’s ability to exercise. Unhealthy eating habits, such as high-calorie foods, an alternating diet, and frequent treats can also bring on this condition.

Other common causes include:
• Neutering
• Underactive Thyroid


Obesity is diagnosed primarily by measuring the animal’s body weight or by scoring its body condition, which involves assessing its body composition. Your veterinarian will do this by examining your pet, palpating its ribs, lumbar area, tail, and head. The results are then compared to the breed standard.

If a pet is obese, it will have an excess body weight of approximately 10 to 15 percent. In the nine-point scoring system, animals which have a body condition score greater than seven are considered to be obese.

Obesity can increase the risk of many diseases including:

1. Arthritis
2. Diabetes
3. Cancer
4. Heart Disease
