Is it normal for them to revert back to old bad habits, like biting when over a year old? Fozzie almost completely stopped biting, except for some plsying, but now he's back to coming at us teeth first on the couch and to wake us up. Anyone experienced this, and if so how did you deal with it?

Edit: he's a poochon (poodle/buchon frise)
