Genetic Testing Cavaliers for Heart Disease

The Functional Breeding Podcast

This episode is just me (Jessica Perry Hekman, DVM, PhD) - talking about a new genetic test for the risk of mitral valve disease in Cavalier King Charles Spaniels. Cavs are at incredibly high risk of this disease and get it at much younger ages than other breeds. What does this new test mean in terms of predicting if your Cav is at risk, and whether a particular Cav should be bred?
