People like you are what gives Pit Bulls a bad name. I have no issue with Pits, I have friends and relatives who own them and they are sweet, loving, good dogs. But your dog has already attacked and injured my friend's little white terrier mix; today he decided to try me and my 2 German Shepherds on for size. Lucky for him I recently picked up a can of dog repellent spray. I sprayed him full in the face with it and he tucked tail and ran. I have 2 pieces of advice for you: 1) Take him to the vet--I hear that stuff's nasty; and 2) Keep him penned up. I occasionally forget my dog repellent spray, but I never forget my pistol.
