Pugs are dogs that can keep their owners laughing, I take that has a huge benefit. A lot of us need that laughter now. They are very playful and because of that by playing with a dog we can keep our mind off from other matters that may be upsetting us. These dogs are also smaller dogs who can do great in apartments so you don't have to have a house or a huge yard for these little guys, which I say is also a plus for some people.
Their grooming doesn't take much. The creases on their faces do need to be cleaned regularly but besides that they are pretty simple to take care of.
