One of the world's oldest dog breeds, pugs are also one of the silliest and sweetest. The AKC calls them "even-tempered, charming, mischievous and loving" and this small breed shows up on nearly every list of best family-friendly dogs.
Pugs are incredibly outgoing with a lot of dog in a little package. These people-pleasing pups come in fawn or black. They do well at obedience training, but don't need a lot of exercise, making them perfect for small homes or apartments.
