Heart Disease in Dogs — Which Breeds Are at Risk and Why Early Detection Changes Outcomes
Heart disease is a leading cause of mortality in dogs above 8 years. Mitral valve disease (MMVD) predominates in small breeds — Cavaliers, Dachshunds, and Pomeranians. Dilated cardiomyopathy (DCM) primarily affects large breeds like Dobermanns and Great Danes. Early diagnosis and appropriate medication significantly extend both lifespan and quality of life.
Prescription Cardiac Medicines Available
This section stocks Cardilock and Vetmedin (Pimobendan), Cardiopet FM, Atenolol, Furosemide, Spironolactone, and Omega-3 and Taurine supplements for DCM management. Following the EPIC trial, Pimobendan is now recommended in the pre-clinical stage for dogs with moderate-to-severe cardiac enlargement on X-ray — before heart failure symptoms develop. Diuretics manage fluid accumulation in congestive heart failure.
What Cardiac Patients Need Beyond Medication
All cardiac medicines require a veterinary prescription and echocardiographic diagnosis. Dogs on cardiac medication need echocardiographic re-evaluation every 6 months to adjust dosing accurately — medication alone without monitoring is incomplete management.
