Find and talk to reputable breeders of the breed you’re looking at. If you’re looking to show, talk to handlers who do the show circuit.
I am not looking to show, I have a wonderful dog of a great breed and would like to find more and breed them. My guy cannot breed, but others can.
I just want dogs of good heritage and have them make puppies. There is something about new life!
That is why I have chickens and cats. The children haven’t started breeding yet, but at some point I expect them to wed and bed.
