The dog's okay. He gets on my nerves too, mainly because I'm the one who makes him behave, so I'm the one he asks for everything.
He likes the comfy couch and up until we replaced the living room furniture (with more used furniture) he'd only get up there when we were gone.
I'm sure what happened was that he was on the couch and Jr. went to get him down by grabbing his collar. I would've just pushed his butt off. He won't challenge me.
A few days of staying in the crate and he'll remember to stay off the furniture.
