At any given time there  might be  more puppies currently available than is listed on this website...
This can happen for various reasons one being bigger litter size!   
Also, a certain waitlist that appears full may not  be full in the long run, since I often place  families on more than one list at a time to increase the chance of them getting the puppy they want..  In turn, they will remove off of a list (or two) when choosing their puppy, thus opening up a spot on another waitlist!
