A study finds that more dogs are heavier than recommended body weight.

Maybe the reason many dogs are obese and overweight is because owners have less time to exercise or maybe dogs are fat because they aren’t being fed properly. But according to the Chicago Tribune, the Association for Pet Obese Prevention reported that one-fifth of our dogs and cats are obese. For a dog to be obese, it must be over 30 percent the recommended body weight for the dog.

The result? Many dogs suffer from dog arthritis, dog diabetes, high blood pressure and kidney disease.
