Here is a perfect example of why we need to use the diversity testing. On paper this dog is a product of a complete outcross. There are very few common ancestors in the sire and dam pedigree. However several of the puppies in the litter have autoimmune thyroiditis. Obviously both mom and dad (dad has both of these haplotypes, mom has not been tested) have 1054 and 2022 and these are two very common haplotypes in Havanese. On top of that look at the IR value. The IR value is higher than some of the line breedings I have done. Before this testing the breeders may have come to the conclusion that that outcrossing was not a good thing. Look what happened, I outcrossed and got this! However, now we have this wonderful tool to help us avoid this kind of pitfall. This was, in fact, unbeknownst to the breeders, an intense line breeding.
