The survey deals with a diagnostic method of dilated cardiomyopathy in dogs, related to a new method of treatment. Dilated cardiomyopathy is the main disease causing death in large dog breeds, having genetic determinism and palliative methods of treatment. The disease consists in the dilation of the cardiac muscle and the progressive decreasing of the heart contraction strength. The hypothesis of the treatment, which offers hope to be revolutionary, is based on the histological similarity between nodal cells and neurons from the brain. The treatment is in a theoretical phase and consists in using culture neurons in order to supply the contractil function and the cardiac automatism. Introduction: Dilated cardiomyopathy is a progressive 1 disease of the myocardium, the dilatation initially concerning the left ventricle 2 , but it extends to all cardiac cavities, being accompanied by alterations of ventricular kinetics and arrhythmias 3. Dilated cardiomyopathy is the most common of chronic cardiomyopathies 1. It is demonstrated the predisposition of large dog breeds towards dilated cardiomyopathy (Doberman, Pincher,
