In Hawaii I see a great deal of Labs or Lab mixes but mostly mixed breeds of all sorts at the two dog parks with a sprinkling of every type of pure breed. I often see people carrying around Chihuahuas. When first trying to decide what breed of dog to get, I visited a pet store every Sunday for months for their "Puppy Swap Meet" where breeders came selling their puppies. Lots of small dog breeds. Quite a few litters of Pit Bull and PB mixes. Daily ads in the paper for PB pups. At the Humane Society I see a large percentage of Pit Bull mixes. I was told uncontrolled breeding for fighting, the mentality of some people, resulting in many abandoned.
