Prince is approximately 1+ years old according to the shelter I adopted him from in Sacramento. I've only had him for just over 1 month and I have already grown quite attached to him. Giving him up is the last thing I want to do. But I can't keep him where I live because he often acts very aggressive to strangers and he did bite a maintenance worker here. It did not break the persons skin fortunately and personally I don't think he meant any harm. But he does get carried away and at times I'm afraid he does mean to harm. I'm no dog expert but I suspect he was not socialized correctly, if at all. Personally to me he is as loving and good tempered as you could ask for in a dog. He's ok with my neighbors he has met as well. Also he has a bad left front leg. It looks like it didn't develop properly as it's small and crooked. But it doesn't slow him down a bit. He can still outrun me by a long shot. I really hate putting him up for adoption but he a different environment for now. I hsve no idea if he's a purebred or a mix so I checked mix. He doesn't look like a mix to me but I have no way of knowing.
