I have been breeding Australian Shepherds and Pomeranians. Our Aussie programs has been up and running for the last 15 years and our poms just started about a year ago. We do a full panel of genetic testing on all of our breeders. Any parent that is a carrier in our programs all babies born are tested against what parents are carriers of. We are very transparent.
This breeder hasn't written any updates yet, maybe ask them why?
