Pugs are true companion dogs: they can be quiet and docile, but also vivacious and teasing, depending on their owner's mood.
Although strong willed and opionated, they are rarely aggressive. They are most suitable to families with children. Children like their sense of humor and soft, velvety coat. Their protruding button eyes and wrinkled short face give them a little monkey look (hence their name).
Pugs in turn are quite tolerant with children and sturdy enough to romp and play with children. Add to that the fact that they are excellent watch dogs, always alert, but not yappy, and you obtain the perfect mix of a top companion dog.
