For the AM attacks, some focused play time might help. If Quincy is just completely revved up, he might not be able to settle down until he's burned some energy. You don't want to let him keep acting like a little thug, but you can't expect him to just sit pretty and sing with the choir while his brain is on hiatus. In another thread I described the following clicker training exercise as a suggestion to someone whose puppy kept biting her husband:
Your husband's unhappiness with the situation is probably contributing to the problems. Being a young creature, she wants attention. If she can't get good attention, she will settle for bad. She will keep trying to push his buttons until he reacts.
Games are a really good way to channel bad behavior into good behavior. Here's an example. Earlier this week my husband asked me how to stop out puppy from biting him. The little twerp had lunged, caught my husband with a sharp little puppy tooth, and drawn blood. When I went outside I found the puppy acting like a complete maniac. He tried to hump my leg. He jumped and tried to bite my hands. It was pretty obvious how he has slipped and nipped my husband. He was just wired.
The first thing I did was to shift my leg so he bounced off my knee, hard. That ended the humping attempt. Next I put my hands in my pockets. That ended the hand biting game. Then, since he clearly wanted to play hard, I did some challenging off leash heeling with him. I walked and ran all over our yard. I jumped up on benches and rocks. I climbed stairs. I changed directions abruptly. Every time I did something that require him to think and adjust, I looked down to my left. If I saw a puppy looking back up at me I would click and give him a treat.
The first couple times my hand came out of my pocket he tried to nip. Then he soon figured out there was no reward in nipping. The reward only came when he put himself at my left heel. He started working really hard to follow along as I moved around the yard. To me, this was training. To him, this was a game of chase in which he got treats when he caught me the right way. After 15 minutes of this work my very bad puppy was acting like a very good puppy.No anger, no punishment, just play.
