My wife and I were walking through a public, unfenced, park in Boston, Ma. When we wre surounded by unleashed dogs of all types and thier owners who were trying to be friendly, I guess. Now, we have a 2 yr. old blue AmStaff, and a 9.5 yr old .5 pit .5 rottie. They seemed oftly upset when we told them to stay away from our dogs. ( who were leagaly on thier leashes ) Now you know and we know that if anything happened the big bad "Pit Bulls" would be getting youthanized.
