My sister in law, Connie, let her Lhasa Apso, Buttons, stay with her mother, Mamie, a few times. .Once, Buttons decided to bite Mamie. She bit him back. He never did that again. .He came close with me, but he clomped his mouth closed just before his teeth got to my hand. I didn’t feel the need to “bite him back”, but I didn’t tease him by threatening to take back the pig ear that i’d just given him.Ever again!!!
