Nothing if you can at least semi-control yourself.... Tucker can't.
Pugs are awesome. They shed a lot and are stubborn, but they get along with everyone and everything, and they are cute.... If you don't have a fence though.... Be careful, they tend to turn off their ears and go where ever they please. If you have any other specifics let me know.
lol...well I can semi-control myself. But it usually involves duct tape, rope and a straight jacket.
Oh that's cool, I really didn't want a little dog. But if I am going to get one, I do want it to have some attitude.
I have an 8ft privacy fence surrounding my back yard so unless they are good climbers, I should be ok. Oh and thanks, if I think of any questions, I'll definitely come bug you about them.
