Dobermans are very prone to heart disease (cardiomyopathy) and vestibular disease, other than that a Doberman breeder should have tested sire and dam for VWD (a blood disorder) Hip Dysplasia, and they should be given a CERF exam (eyes). These tests should be available for you to see before committing to buying a puppy.
