Story
I’ve had him since he was a puppy and he’s been an amazing dog. He’s very smart very loving. He’s never had a problem with people until he got into an altercation with a great Dane. The great Dane started the fight. A couple weeks later, my mother came home from the UK. We were at a rest stop coming home and there was an older lady with two canes she wanted to see beaux and I told her that he was acting a little different lately. She said oh well, let’s see and she came towards him anyways. He jumped up and nipped her on the lip. There was some blood, but it wasn’t that bad. That’s the only issues I’ve ever had with him. After those altercations, I went and got him neutered. He’s always had a good temperament, but he’s been a little different after those two altercations. That was in October 2025 he hasn’t had any altercation since.
