My dog is a pitbull.
An extremely well-behaved, unthreatening, neutered, vaccinated, worm-free, flea-free pitbull. I pour too much time and money into him to allow him to be bitten by a dog that might have any number of diseases because his owners don’t care enough to bring him inside from the rain, let alone to a vet.
Let your pit bull take care of himself then. He’s not scared of no chihuahua is he? Or of recently pregnant 7 pound house cats?
