I have a boxer. Dapper Dan. He's very sweet and gentle. Great with everyone. Plays a little rough with other dogs but never mean. and he calms down quick. He's very small for a boxer. Not even 60 lbs. My girlfriend has a pitbull. Sophie. Very bullish and rough. It seems like she just doesn't know her own strength and has too much energy for her own good. We have trouble seeing each other sometimes because we need to be home with the dogs. So we finaly introduced them. They both pulled at the leashes to get to each other, they sniffed and then and then the Pit bit my dog in the face. Like I said, Dan is sweet and gentle and has never been mean, but he's tough. When we brought them close again he bit her right away. Real good. she backed down a lot and did like a belly crawl thing to the water bowl. Then she went up and growled at him and snapped and he bit her good on the back side and wouldnt let go. I had to give him a crack. If both dogs were like Dan I'd probly let them go at it and get it out of their system. But I'm very scared with the pit. I've had Rott's and Huskies and this is the strongest dog I've ever felt. I'm worried she could seriously hurt or kill him. Any advice on getting them aquainted? My only thought is to muzzle them both and let them just paw at each other for a while. Good idea or no? Thanks. Sorry it's so long.
