Which dog breed is predisposed to dilated cardiomyopathy with geographic variation?

Explanation:
Dilated cardiomyopathy is a hereditary disease in dogs where the heart muscle becomes weakened and the chambers dilate, leading to reduced contractile function and typically signs like exercise intolerance or coughing. The Doberman Pinscher has a well-established genetic form of this condition, and how commonly it occurs can vary by geographic region due to differences in breeding lines, genetic mutations, and how actively dogs are screened. This combination—a hereditary basis and regional differences in prevalence—fits the Doberman Pinscher particularly well, making it the breed most classically associated with DCM and its geographic variation among common breeds.
