There will always be another litter, always another puppy. It is hard to wait but no one else has to pay the fees in money, time, and energy when the pup is battling for your current dogs attention.
That is what keeps me in line. I have a litter I am tentatively on the list for but if the right bitch doesn't happen I will be okay, my sport dogs are still young and on the other hand my pit bulls are reaching the ends of their lives so if it stays just us for a while we'll probably be better for it.
Perspective to counter the pushers.
