Along with check, include a short note with your name, address, best email to be reached at, best phone number, and any specifics I need to know about what your first choice in a puppy will be, such as: sex preference, size at maturity, color, which litter are you most interested in. Thank you. Also, please, please, please do not tell me the "check is in the mail" if it is not. This hurts future families who would really love to have a puppy.
