Dog rescuers, flush with donations, buy animals from the breeders they scorn

The rescuers call many breeders heartless operators of inhumane "puppy mills." The breeders call "retail rescuers" hypocritical dilettantes. But for years, they have created a shadow market in which rescuers enrich breeders — some being paid $5,000 or more for a single dog — and some breeders say more dogs are being bred to sell to rescuers.
