Contact your local animal shelter or animal rescue group. These organizations can help with suggestions on how to screen potential adopters. You can place an ad in the local newspaper, ask your vet or ask friends or relatives if they are interested in adopting the pup. If a stranger is interested, prepare a list of questions to make sure their intentions are to give the pup a good home for its life. Visit their home to make sure it's the right place. If any of the perspective adopters refuse to comply, look further.
