Hi ladies, Any of you dog owners out there please give me your opinions on this: Background: My pug, just about a year old, male, neutered, had all his shots. Very playful, kinda lazy now, good, loving dog. Yesterday I took him out to "go" and we were only outside for 30 seconds when my best friend pulls up in the car. He has been around her and her daughter and husband many times now since we've got him. Well, they come up to him and "hi milo!" and start petting him and he was totally acting normal. They were all bending down in front of him petting him. I was holding him on the leash. All of a sudden he kind of freaked out and started growling and bit her daughter!!!! He went for her ear, her neck, and her arm. The only marks he made were on her arm, about 3 scratches on her arm (poor thing) and not very deep but still broke the skin. She did not step on him or try to hug him or anything like that. They were all just petting him and he fliped out?????? I don't understand this at all. He has NEVER done this before. I scolded him and right away I could tell he knew he did something very very wrong and has been lowering his head at me ever since cause he knows I'm very unhappy with him. But, I took him to the vet and he's fine. No illness at all, hasn't been acting funny, he went right back to his normal self after they left. He did continue to bark at her daughter the whole time she was here though. But, she did nothing to him to provoke this???? Any help would be appreciated.
