Dilated Cardiomyopathy (DCM) in English Cocker Spaniels
High Risk Category: Cardiac Typical onset: 4-10 years Hereditary: Yes Est. treatment cost: £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.
