I know a lady in the Phoenix city limits with 8 dogs. She said she isn't breaking any laws because it goes by how much land or how big your lot is. All of hers are under about 15 lbs anyway... Shih Tzu's, Pugs, (mixes of those two due to an accidental litter) pomeranians and chihuahuas. She said, "they really only make up about 3 bigger dogs."

I always wondered if she really was allowed to have that many. But she takes such awesome care of them I wouldn't ever turn her in even if she did have too many.
