Screening Scheme Description

DNA test - DCM
Dilated Cardiomyopathy


Details about the disease

DCM is a heart condition which causes the swelling of the lower chambers of the heart (ventricles). This reduces the heart’s ability to pump blood and leads the heart to become large and beat weakly.

Clinical signs

Clinical signs include collapsing, appetite loss, lethargy, gradual abdominal swelling, coughing and gasping for breath. These signs may not be apparent for years but will show eventually, and in Schnauzers it has been reported that the onset is typically much younger than in other breeds.

How it is inherited

The disease is described as an autosomal recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
