This is a timely subject for me. I'm in the process getting ready to bred Diva and when I say that I'm meaning in around 1.5yrs. We are looking at her structure and type(have her evaulated by others), getting her health tests done(those we can) and thinking about what we want in a mate. My number 1 goal is health, followed by structure and type. An all around sheltie-pretty and functional. I would rather have a puppy live to 17-18yrs pain free then it become an AKC champion. The process is all very daunting.
This will be my first litter I've bred myself. I have been disappointed in the opinions of some show breeders that I have met in my journey. It seems that the almighty AKC Ch is the only thing that matters to them. Bad bites, bad hips ,low thyroids, VWD, you name it, no problem we will just place those puppies and pretend that they are not there. Their dogs don't do anything but show so who cares if they can move or not. Fortunately these people are not the majority. But they are the ones that PBE are talking about.
I have also met wonderful people who bred for show quality,sound pups who are not only beautiful but healthy and long lived with full heath testing on the parents. Where is the press for these people? A problem with one of their pups. They step up and help and sometimes with pups not of their breeding just because the love the breed.
It is difficult to bred any dog and avoid all problems. Mixed breed are no healthier than purebreds. Inbreeding, linebreeding does not cause the problem. The most unhealthy dog I have known was a mix 1/2 Lab, 1/4 Brittney and 1/4 Chessie(certainly not inbred), she had Hip dsyplasia, epiplesy, allergies, Addison's disease and immuned mediated polyarthitis. She died at 2 due to her health problems. There are no data bases or breed clubs tracking the disease in mixes so they don't get the same press. Knowledge and breeding for moderation is the weapon against breeding unhealthy dogs. The more you know about the line your breeding,follow your puppies,note the health issues in those dog(and siblings, aunts,uncles etc) and the ages and causes of deaths, the more informed the decsions we can make as breeders for the next generation. This can only happen if breeders are willing to have open dialoges with others regarding their lines.
BYB or hobby breeders do not get a pass here either the standard for health testing and line knowledge should be the same. We owe it to our dogs.
