I apologise for not making it clear enough that I separate “award winning show dog” breeders from “puppy mill” breeders. There is a special place in hell for those that run puppy mills. The same goes for the buyer though. It isn’t hard to figure out if you are buying from a responsible breeder. There is typically a long waiting list (we waited nearly two years for our boy) and there is a long “who are you and can you properly look after a dog” process before you even get on the list.
At the end of the day, puppy mills exist because people buy from them.
Responsible breeders work hard with the respective breed groups to improve the health standards, and a lot of work is underway to introduce new bloodlines and standards to unhealthy breeds. That is not to say that all breeders are good breeders, or care much about dogs’ health, but there is a definitive push for change going on towards improving the standards.
