Flat-faced dogs like Pugs and Bulldogs have problems with breathing, because their snout is shorter than in other dogs, and they can therefore run out of breath easily. As they are also prone to overeating, they do require some special treatment.
It is recommended to keep your flat-faced dog engaged with short, mild exercises, a couple of times a day. Puzzle toys are a clever way to keep them active. If they aren’t able to get enough outdoor exercise, make sure to keep them occupied in the home, and to monitor their diet.
