Obesity is caused by either too much food (excessive dietary intake) or too little exercise (inadequate energy utilization). The most basic remedies involve dieting and increasing exercise.
Large studies have found that approximately 40% of dogs are either overweight or obese. Certain dog breeds are more prone to being overweight, including Golden Retrievers, Dachshunds and Shetland Sheepdogs.
Obesity is a risk factor for many canine (and human) diseases, including diabetes, heart disease and arthritis.
