If a dog is aggressive the owners have failed. I say they should set up a shelter for aggressive and unmanageable dogs where they try to rehabilitate the dogs. The former owners will have to pay for it all as their punishment and, if the dog cannot be rehabilitated, for life. If you don't have money to take care of a dog properly, don't get a dog. Also, I cannot believe that they can't pay up for the dogs treatment. Seems to me that they just don't want to because they will have to give up something that they like (more than their dog) in order to be able to pay. Do they smoke, drink, drive a car, etc?
