A hidden supply chain finally comes into focus.

Designer dogs were once marketed as harmless hybrids with cute names and celebrity appeal. But investigators now warn that a growing number of these mixes trace back to large backyard breeding networks operating behind closed gates. The deeper authorities look, the more they find improvised kennels, unregulated litters and buyers who never realize the origins of the puppies they hold. What seemed like a boutique trend has quietly become a pipeline with consequences no one expected.
