When I was a kid we had a pug and after it got a bath it would tear ass around the house at full speed, running into walls rubbing its face on the couch and falling all over itself, its eyes bulging out in this expression of deranged intensity, while my little sister shouted "GO CRAZY! GO CRAZY!"
I don't think so. My grandmother's got a pug that's extremely well behaved, and generally extremely calm. And he's only a few years old. I think the worst thing he ever did was eat a couple of dollars.
