Hereditary Weaknesses

One of the goals of reputable Cavalier King Charles Spaniel breeders is to raise animals that will have as few hereditary weaknesses as possible.

Make appropriate inquiries of any breeder regarding the sire and dam of any puppy you are looking to buy. Under ideal conditions, you would want a certification that both the sire and dam have been examined by a cardiologist for signs of mitral valve disease and found to be clear at age 5. 

You may also ask for evidence that the sire and dam’s eyes have been cleared by an ophthalmologist.
