PETA Animal Protection Campaign

PETA argues that it would have been better for animals had the institution of breeding them as "pets" never emerged, that the desire to own and receive love from animals is selfish, and that their breeding, sale, and purchase can cause immeasurable suffering. They write that millions of dogs spend their lives chained outside in all weather conditions or locked up in chain-link pens and wire cages in puppy mills, and that even in good homes animals are often not well cared for. They would like to see the population of dogs and cats reduced through spaying and neutering, and for people never to purchase animals from pet shops or breeders, but to adopt them from shelters instead. PETA supports hearing dog programs where animals are taken from shelters and placed in appropriate homes, but does not endorse seeing-eye-dog programs because, according to one of their Vice Presidents, "the dogs are bred as if there are no equally intelligent dogs literally dying for homes in shelters."
On euthanasia
PETA opposes the no kill movement. The group takes in feral cat colonies with diseases such as feline AIDS and leukemia, stray dogs, litters of parvo-infected puppies, and backyard dogs, and says that it would be unrealistic to follow a no-kill policy in such instances. They offer free euthanasia services to counties that kill unwanted animals via gassing or shooting—they recommend the use of an intravenous injection of sodium pentobarbital if administered by a trained professional, and for severely ill or dying pets when euthanasia at a veterinarian is unaffordable. They recommend euthanasia for certain breeds, such as pit bull terriers, and in certain situations for animals in shelters: for example, for those living for long periods in cramped cages.
