If anyone told me I should come over so their dogs can get to know me so they (the dogs) wouldn't attack me accidentally, I would NEVER go to that house at all, period. I don't care what kind of breed of dog they have. Those people sound like the same people who can be proud of the fact that their mulitple bully breeds eat from the same dog bowl at the same time. Accidents waiting to happen...
...Just another observation. I drive about 4k miles a month for work. I do frequent various urban areas. some "not so nice" areas as well located within those urban areas. On average, in those areas, I see various bully breeds being handled by owners in their "local" setting. It's interesting enough that the dog I observe and come across the most is the bully breed in this urban enviroment, and I won't get into what could be considered racial profiling, but there are some interesting observations, at least for myself.
