Like most of the majority is saying here, getting a quality puppy from a reputable breeder would be the best route, esp if you're wanting a smaller pup. Reputable breeders will not purposely breed for tinies, it will sometimes happen in a litter.
Unethical breeders will use tiny females (3#'s & under) to get the tiniest puppies possible...to me, this is inhumane & animal cruelty. |
