A 2016 study by the Association for Pet Obesity Prevention (APOP) found that nearly 59% of cats and 54% of dogs were obese. Certain dog breeds are more prone to being overweight, including Golden Retrievers, Dachshunds and Shetland Sheepdogs.
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.
Obesity is a risk factor for many canine (and human) diseases, including diabetes, heart disease and arthritis.
