Dilated Cardiomyopathy (DCM) in Dogs
Dilated cardiomyopathy (DCM) is a serious heart disease in dogs characterized by weakening and enlargement of the heart muscle, leading to reduced pumping ability. Some dogs have a strong genetic predisposition, while others may develop DCM due to environmental and nutritional factors, including dietary deficiencies.
Many dogs with DCM are asymptomatic in the early stages but when clinical signs do appear—such as coughing, exercise intolerance, collapse, or difficulty breathing—the disease is often already advanced.
Diagnostics include chest X-rays, Pro-BNP testing, blood pressure measurement, and routine bloodwork. The gold standard for diagnosis is an echocardiogram performed by a veterinary cardiologist, which allows direct assessment of heart size and function.
Treatment options include conventional and integrative medicines, including prescription cardiac medications when indicated, as well as supportive holistic therapies such as hawthorn berries, dandelion, vitamin E, taurine, L-carnitine, omega-3 fatty acids, a whole-food balanced diet, and the importance of good air quality in the home (avoiding candles, incense, and other airborne toxins).
We conclude with an honest discussion of prognosis, which varies widely depending on cause, stage at diagnosis, and response to therapy, and close with practical guidance on early detection and proactive care.
Whether you’re a dog guardian, breeder, or veterinary professional, this video will help you better understand DCM—and what you can do to support heart health early and thoughtfully.
