They do. Pugs are very picky eaters, so you should be too if you want your dog to thrive. As with humans, dogs have specific dietary needs. There are four basic types of dogs—beagles, hounds, terriers, and retrievers. Beagles have long, strong legs and a shorter back, making them great for hunting, while hounds are excellent swimmers.
