I was visiting a friend who owns 2 male APBT. He said his dogs were fine and we tried to make the introduction with my female pit mix. Within seconds a fight was on both dogs looked to be latched on my dog, luckily my friend and I were standing close by and separated the fight quickly. My dog surprisingly didn't break any skin but has a huge golf ball sized seroma/hematoma on her neck but seems fine and just ate a bowl of dog food in good spirits. I had a minor bite on my knee from my friends dog and my friend was bitten fairly severely on the hand by his own dog. I think it was my dog's lucky day to get away which such little injury.
