I read your title and said that sounds like Buddy let's read this
It's Brownie, no wonder I thought it was Buddy

They seem so much
alike.
Buddy does not do that though(he bit the groomer instead) but a groomer (YorkieRose) I think
mentioned about putting peanut butter in the roof of their mouth
while they were being groomed to keep them still. Sounds like a good
idea. Good luck.
Browine be still or your going to be earless one of these days
