Canine parvovirus one of important infectious diseases causes profound morbidity as well mortality dogs. It found that canine infection can result non-thyroidal sickness syndrome. relation between pathology and will pave way for therapeutic preventive measures this disease. This study was conducted on 61 dog carcasses brought to Department Veterinary Pathology, College Animal Sciences, Pookode during year period. Among cases, nine were be positive constitutes an incidence 14.75 per cent. Analysis gross histopathological lesions cases goal investigation. observed paleness nodular growth encountered lymphocytic thyroiditis, colloidal goiter, c cell hyperplasia, severe fibrotic changes neoplastic lesions. Further research required understand pathophysiology euthyroid sick syndrome parvoviral infection.
