Okay, well I have been thinking it over and I know you might think I'm stupid cause I always think ahead without thinking about it first but I decided I should avoid Bull, for awhile, anyway. I was thinking about it and I don't know if this dog has had his shots, or if it is a girl or boy, neuteured or spayed, it's temperament...so I decided to try to forget about him. I will try though, if I see him in the park or around, to speak and get to know the owners. Thanks for the advice anyways.
