Pugs do tend to have genetic problems which can lead to expensive vet bills. Small nares in the nose which also can cause breathing problems. Eye problems due to their protruding eyes. I, fortunately, haven't had any of these problems with my pugs. However, if you are considering a pug as a pet, you need to be aware of these potential problems.
Pugs are extremely loyal and patient little creatures.
Because of this tendency, it is very easy for them to become overweight. A regular feeding schedule is the best way to handle feeding the pugs. Too many treats will keep a pug off his feet. He'll be too full to exercise. I do recommend a high-end food.
