Most pound dogs come without a r sum . Researchers don't know their ages, medical histories, or if they have taken medications or experienced prior health problems. This compromises the results of many experiments performed upon them. Many supporters of pound-dog experimentation argue that the animals in question will die anyway and therefore have nothing to lose by becoming experimental subjects. Yet, this argument falls short.
Experimenters take that chance away.
And even if the animals do face euthanasia at the pound, it can hardly compare to the horrific experiences awaiting them as experimental subjects. All will undergo the stress of being moved from shelter to animal supplier to experimental facility. Most will experience something much worse. A study of 52 different published experiments found that 66 percent of them involved significant pain for the dogs, while 13 percent involved severe pain to unanesthetized animals. On average, these experiments went on for 10 days.
