I'd gently smack her on the ears or nose, they hate that.We were both exhausted last night after walks and command training. She seems to have settled a bit but I'm working all day today today till 7pm so I'm presuming she'll be a little wound up. She jumped up on me and then bit my hand this morning when I got up, that ****** me off. I left instructions with my son who's home today as to crate times and walks. Thing is any positive training will all be forgotten when she gets back to her owners.
My brother had a dog who had an annoying trait of biting your heels as you walk. As soon as she bite my heels, smack to the ears. She actually thinks before doing it again
