Why does ASPCA kill there dogs?

The ASPCA does not have a policy of killing dogs indiscriminately; however, they may euthanize animals in their care under certain circumstances. This typically occurs when an animal is severely ill, injured beyond recovery, or poses a danger to public safety. The organization strives to minimize euthanasia by promoting adoption, providing medical care, and working to reduce pet overpopulation. Their goal is to ensure that every animal has a chance for a safe and loving home.
