Quick answer

Dilated Cardiomyopathy (DCM) is a high-severity condition documented in the English Cocker Spaniel. It has a hereditary component, so ask breeders for health-screening documentation. Estimated treatment cost is £2,000-£6,000/year.

Dilated Cardiomyopathy (DCM) is one of the most frequently diagnosed conditions in the breed within the English Cocker Spaniel. Common indicators include exercise intolerance, coughing, and laboured breathing. DCM is a disease of the heart muscle causing the chambers to enlarge and the walls to thin, reducing the heart's pumping efficiency. It progresses to congestive heart failure if untreated and is a leading cause of cardiac death in large breeds. It typically becomes apparent at 4-10 years. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £2,000-£6,000/year, making comprehensive pet insurance a practical consideration.
