Yes, keep in mind these breeds aren't banned in every county/state. For instance, in Colorado, Pit Bulls are banned in Denver but not elsewhere. As southerngirl mentioned dogs get banned for many reasons, it really just depends on incident rates and problems. For example, let's say there's a town that has lots of golden retrievers that were bought from puppy mills and they're wreaking havoc because they all have serious genetic problems like ADHD and whatever other combination. With that many poorly bred goldens there's probably a ton of bites so the city council decides to ban them... As I mentioned previously, some towns have ridiculous rules like requiring dogs to wear diapers outside of their yard.
