Runs through the house like he's on fire
You're calmly watching TV when your dog bolts past like a shot out of the blue. You have no idea where he's going or what set him off. All you know is that suddenly he's gone nuts.
Don't ship him off to the psych ward just yet. The poor thing is probably just bored. "Satisfied, fulfilled dogs do not do this," Millan says. "If you're away most of the day, or don't play with him enough, his energy has nowhere to go. It just builds up inside him until it explodes. This could be triggered by a scent, the sight of another dog on TV, or just his own frustration."
