Good breeders typically do all of the genetic testing on the parents of a litter before they breed. Research has indicated that this is much more important than ever before.
Genoscoper Ltd. (a Finnish company specializing in animal genetics and gene testing) has published the most conclusive study ever on canine hereditary disorders. The study was done with researchers from the University of Helsinki and the University of Pennsylvania and published on PLOS ONE, 8/15/16.
They tested 7000 dogs in about 230 different breeds for a predisposition for about 100 genetic disorders. They found that 1 in 6 dogs carried at least one disease. Additionally, 1 in 6 breeds that never tested positive for one of the diseases had a predisposition for it.
This information will help dog owners understand and identify early signs of inherited disorders which may enable pet owners and veterinarians to better able identify health issues earlier and perhaps prevent suffering for the dog.
This important study will lead to further research about inherited diseases in dogs that will help the overall health and well-being of both dogs and other pets.
