It was just a question....
First, I don't think a deformed puppy would be a reason to have it euthanized. We were going to get a deformed cockapoo, but she got sold when we were on our way.
Now, if I were a breeder, I could most definitly not do this. I wouldnt be able to stand myself if I did. I would drive miles away to take the puppy to an emergency vet. I stand outside on a cold night and I'm freezing, I could just imagine how a little tiny new born puppy would feel locked in a freezer. *shudders*
