Pugs are smart, funny, loyal, and affectionate. They are great with kids and are always ready to play. Since they are so smart, they may get bored with repetition in their training. They are also very tone sensitive, so harsh punishments can be overkill. Pugs play well with other pets, and are generally good with new faces as well. All in all, the Pug is one of the most easy going dogs around. .
