Technically, yes SDs are exempt from breed bans. But, you know how hard it can be to convince local yahoo cops that SD laws exist, they can be even harder to convince of the breed ban exemption. I would never take a dog (SD or not) that even resembled a pittie into Denver or KC. There was a case last year of a man who's pittie mix SD was seized when he stopped at a gas station in Denver. For the safety of my dog, I wouldn't do it. But then, I won't spend money in a city that has a BSL anyway.

And Jin....I mean Ranger...you know who you are

No dog breed is genetically prone to aggression over another. Its in the breeding and the rearing. As the president/co-founder of an anti-BSL organization, I have more info on this than you ever would want to read!
