Need help with mouthy adopted dog
We adopted our GSD from the military -- he didn't show enough of a work drive so they booted him. (He's got an awesome couch drive.)
I've had him in a manners class so he knows some basics, but he's still way too mouthy with me, the kids and the kitty. He never hurts anyone at all. But his mouth looks like an alligator is coming down on us and I want him to stop.
I have no clue how to train him out of this lovely behavior. I assume that the military didn't care that he mouthed.
Any suggestions? The manners class I took him to was with a clicker and treat rewards.
