Sorry for the loss of your family members
I have a couple of questions. I'm fairly new to the breed, so some of this is new to me. I've never heard of this disorder or condition. If it has to do with inbreeding too much or line breeding too tight, I might have an assumption of why. The breed started off of two dogs, of course the dogs were bred back to their offspring and so forth, or at least so I've read. Please correct me if I'm wrong. Is this something that I should be concerned about when searching for a breeder? Is there a test that can detect it? Which lines carry it,working or showing? What are some dogs to look for that might have/carry it?
