My chihuahua is super protective of me, but is trained. At halloween he loves the kids in costume. He doesn’t like other dogs, unless they understand he’s the dominant puppers.
The other night, I was laying in bed with him and a car pulled into our driveway and he immediately moved so he was in between me and the door. It was like “if its bad, it may get past me but its going to bleed trying”.
He sounds like a very sweet tough guy!
