Brought my puppy home last week, all was fine, the biting started so I tried to use the owwww technique and walking away, made the mistake of trying to pick up his ball that slid under the couch he got me good in the ear. It bled, anyway now he won’t stop biting me. I was able to play with home before and get his energy out and now he just wants to bite me not his toys, well only for a little while. He won’t drop his toys at my feet anymore to fetch, he takes them away loses interest and then starts biting furniture. We’ve just started his crate training a couple days ago.
