Bulldog

The bulldog only looks cranky with all those jowls. This calm, friendly dog has a sweet disposition and is "among the most docile and mellow of dogs," according to Animal Planet. The comical, good-natured breed is typically happy to please, although some dogs occasionally can have a stubborn streak. They're typically good around kids and are usually friendly toward strangers.

Bulldogs are a brachycephalic breed, meaning they're short-nosed and can be prone to breathing issues. It can be especially difficult for them in heat and humidity, so watch the exercise on hot days.
