Before you do anything else, call the person you got your dog from and ask for help. Even if several years have passed, responsible breeders care about the puppies they sold and will want to help you find a new home. They may even take the dog back. At the very least, they deserve to know what you intend to do with the dog, and what will happen to it. If you can't remember the breeder's name, look on your dog's registration papers. If, however, you do not feel comfortable releasing the dog back to the breeder, don't do it.

If you got your dog from an animal shelter or rescue service, read the adoption contract you signed when you adopted him. You may be required by the contract to return the dog to that rescue organization.
