Good breeders are very important to reducing the numbers of dogs killed in our shelters.
The good breeder does much much more than raise healthy dogs. One critical factor in reducing dogs killed is to take steps to make sure the puppy is going to a home that is well prepared for the dog. The abilities, needs, and desires of owners differ very much. If the dog is not compatible with the ability and desire of the owner then the dog is at risk. In all too many cases dogs are given up to shelters simply because the owner cannot or will not provide for what the dog needs.
