Hope this helps. It took me a while to find. For those of us in search of the new puppy! Good Luck all in your searches. I am currently scoping out a little male companion for Happy and thought it was one of best sites I have found so far.

Note: I checked most of the breeders on site compared to the AKC "Bad Breeder/Avoid this Person" list and didn't see any of them on there!
