Dilated cardiomyopathy is a major cause of death in Dobermanns. This disease affects the breed more than any other. Nearly 40% of DCM diagnoses are for Dobermann Pinschers, followed by German Shepherds at 13%. More recent studies based on European dogs, however, has indicated that DCM affected rates are much higher for this population than their American relatives: around 58% of European Dobermanns will develop DCM within their lifetime. Research has shown that the breed is affected by an attenuated wavy fiber type of DCM that affects many other breeds, as well as an additional fatty infiltration-degenerative type that appears to be specific to Dobermann Pinscher and Boxer breeds.
