Heart Disease (DCM)

descriptionOverview

Dilated cardiomyopathy (DCM) is a condition where the heart muscle becomes thin and weak, reducing its ability to pump blood effectively. In cats, DCM is almost always caused by taurine deficiency — and since taurine was added to commercial cat foods in the 1980s, feline DCM has become rare. In dogs, DCM has genetic causes but has also been linked to grain-free diets low in taurine. Recent FDA investigations found a correlation between certain boutique, exotic-ingredient, and grain-free (BEG) diets and canine DCM.

restaurantHow Nutrition Helps

For cats, taurine in the diet prevents DCM entirely — all quality commercial cat foods now include it. For dogs, ensuring adequate taurine and avoiding diets heavily based on legumes, potatoes, or exotic proteins reduces risk. The FDA recommends feeding diets that meet AAFCO standards from established manufacturers with veterinary nutritionists on staff.

Moderate activity supports cardiovascular health. For pets with diagnosed heart disease, exercise should be gentle and stress-free — short walks rather than strenuous play. Avoid exercising in heat or humidity.
