Presented results of studying of morphological features of the pathological process at the cardial form of parvovirus infection of dogs. Identified the main criteria for it post–mortem diagnostics.It is shown that based on the results of pathological studies myocarditis of the parvovirus etiology clearly differentiate from other deadly diseases that affect puppies.In puppies aged 1 to 4 weeks, who died suddenly without clinical signs and biochemical changes of blood, which are characteristic for myocarditis, was detected pathomorphological signs of myocardial forms of parvovirus infection of dogs.Histological examination revealed the characteristic morphological changes: 1) lymphocytic (purulent) myocarditis 2) eosinophilic inclusion–bodies in nuclei of cardiomyocytes 3) stromal edema 4) granular dystrophy of cardiomyocytes 5) necrosis of cardiomyocytes with the destruction of the muscle fibers of the myocardium.Also nonspecific but constant morphological features, that is caused by circulatory disorders and heart failure was venous hyperemia of the liver, kidney and pulmonary edema.
