Benny was chained up in the back yard, and got stuck around a bush. I went outside to get him untangled and he got loose from me, I turned around and there was a brindle pit bull in my yard. Benny ran up to him and the dog got a hold of his back leg. Benny screamed, I got a bat and ran up to the dog and he ran off. Benny was walking on three legs and had about 20 bite marks on him and was bleeding mildly.
Took Benny to the vet, he doesn't think anything is broken or dislocated… gave him preventative antibiotics and something for pain. He's walking better, but still a little gingerly.
I've seen the dog around the neighborhood before, off the leash. He's even ran in my back yard and tried to attack Benny before. I did not call the police, because I don't know who is owner is.
