I know Denver has breed bans, as do some of the surrounding areas. Although CSU is in Ft. Collins, this can still be an issue due to surrounding areas following Denver's lead. On the other hand, some of the other communities are moving in the opposite direction and trying to do away with the bans. The bans target bully breeds, but many of the areas are also incorporating other so-called "dangerous" breeds into the bans as well. I live in TX at the moment, so I don't know much else other than that.
From what I gather a lot of vet schools are in more rural areas so you may have an easier time of it... or could be the opposite. I'm very fortunate to be in the position where I own my home, so I don't have to worry about renting. I do know a lot of landlords have breed bans that will include other breeds besides pits.
Not sure if this matters to you, but I'm actually looking at schools in Australia, and there are a lot of breed bans there, including importation. Fortunately my pits don't fall under the bans because they're mixes. They do, however, fall under the bans in Colorado.
