I have a 3 year old American Eskimo male unaltered. My ex has only been around girl dogs. Casper is a well behaved dog and very smart and minds me to a Tee. My EX was trying to get him off the couch, instead of asking me to do it she reached for his collar I told her don't she did it anyway. Casper saw this as a threat because she reached for his neck. He tore he a new arce hole. Not hurting her badly but let her know this is not a way to treat me.
I can do it-he trust me nothing happens. I don't do it often and never raising my voice when I do it.

Casper is 18# of pure fury when he wants.
