I really wish that the ABCA would publish their stud book so that such an analysis could be done on American Border Collies. This work is crucial and it took one non-establishment guy in the Netherlands to do it. I've bought several pedigrees from him, but that's still not enough to thank him for his brilliant contribution to the breed. The first thing you need to read is this:

I am interested on the demonstrated effects of inbreeding in dogs. Specifically I would like to know about border collies or Australian Shepherds. What research on inbreeding can you post?
