A research study of the population genetics of all Kennel Club registered breeds...
"Recognising the importance of managing the rate of inbreeding, the Kennel Club's Population analysis reports allow breeders to review the unique situation for each breed.
If unchecked, inbreeding levels can rise in a breed, and although its effects may not initially be noticeable, this increase can have a significant impact on the health and welfare of future generations.
The breed specific reports... provide a framework to shape discussions on the best ways to improve, or maintain, genetic health."
