The first signs of Dilated Cardiomyopathy (DCM) in dogs are often subtle, including lethargy, exercise intolerance (tiring easily), and coughing, but can also be severe, like sudden collapse, rapid breathing, or fainting, due to fluid buildup in the lungs (pulmonary edema) or abnormal heart rhythms. Owners might first notice a decrease in energy, restlessness, or changes in breathing, sometimes leading to a vet finding a heart murmur or irregular rhythm during a routine check-up.
