Is adopting from a shelter supporting puppy mills?
No. Because dogs that are in shelters come from a variety of places – owner surrenders, strays, etc. Some of those dogs are purebreds (from really good breeders, bybs mills etc but their owners dumped them). Some just got lost. Some are mixes that were lost, dumped as well. Dogs that end up in shelters are there through no fault of their own. Are some of them from mills? Sure. But I’ve seen some very welll bred dogs in shelters too because their owners threw them away like garbage or they got lost for some reason. Money given to a shelter does not go back to funding any breeder. That money barely keeps the doors to the shelter open. But you already knew that.
