It is a disgusting thing to do- that dog was lucky to find you, though. The shelters here are absolutely clogged with animals. One of my dogs was seven when I got him from the local humane society, which has a 52% euthanasia rate. I know sometimes in life people have to make horrible, tough decisions, but I don't understand how you could do that to a dog you have had for seven years. Or seven minutes. He was in horrible shape, too. unneutered, half bald, he had bacterial infections, he was grossly underweight. People would glare at me when I took him for walks.
