I'm glad to hear Beau is going to be OK, I'm also glad to hear the other dog is no longer around to attack any other dogs, too bad the owner didn't join him. There are no bad dogs just bad dog owners. Pit's are working dogs and we see them all the time at dog shows. These dogs are sweet, gentle and kind dogs. Here is the best way to break up a dog fight. If a dog attacks your dog drop your leash and grab the attacking dog by the back legs, it's important to grab BOTH legs at the same time and lift the legs off the ground as high as you can. This will cause the dog to loose its balance and 99% of the time to release it's grip on your dog. If he does not release it's grip on your dog spread the legs like you are trying to crack a wish bone, He will let go. DO NOT LET GO of the dog, he is likely to attack you. Have someone else throw a leash on the attacking dog and place their foot on the leash pinning the dogs head to the ground. It sound brutal but it works. I had saw a neighbors dog attack his young niece the dog was about to kill the little girl. I used this method and he released her. We got the dog into the chain link kennel and called 911. The little girl spent two weeks in the hospital. The dog was so mean the animal control agent put him down with a trank gun. He was afraid to open the gate. I hope none of you reading this ever have the opportunity to use it.
