The Pug has been selected as a companion lap dog. Pugs can easily become overweight couch potatoes but love short walks. Keeping them trim and fit is important because they can suffer from breathing problems. Pugs need to avoid exercise in hot or humid weather because as a flat-faced breed they are prone to overheating. Great care should be taken when exercising a Pug. If you are a light sleeper, be warned that Pugs can snore very loudly. Note that this breed has so many health problems that we do not advise puppy buyers to choose this breed.
