Study reveals powerful long-term impact of DNA tests on dog diseases
18th January 2019 – 9:44 AM
A new study has revealed that the number of pedigree dogs at risk of often painful and debilitating inherited diseases is being dramatically reduced by responsible breeders.
The research, carried out by scientists who work for the Kennel Club and the Animal Health Trust, examined the long-term impact of dog breeders using DNA tests to avoid producing puppies affected by inherited conditions. The study specifically examined DNA tests for eight diseases in eight breeds. Researchers discovered that approximately ten years after each DNA test became available, the gene mutations that caused the diseases had decreased in each breed by a staggering 90 per cent or more.
