Analysis of the structure of liver pathology in neglected dogs

Abstract

 Neglected dogs are part of society, they can be a source of zoonoses and zooanthroponoses. Knowing the pathological changes in the liver of neglected dogs living in urbanized areas, one can study the condition of the latter. Gastric and intestinal pathologies were observed in 87 % of the previously examined animals, pathologies of the kidneys in 57% and pancreatitis in 33% of those animals. The purpose of the study was to  analyze liver pathologies in neglected dogs living in the Altai Territory. The  object of the study was the liver and gallbladder of 41 neglected dogs of different sex and age groups, mongrels, which were supervised by animal welfare volunteers and animal protection organizations in the Altai Territory  in 2014-2021. The animals died for various reasons. The research methods were animal registration, postmortem  examination, statistical processing and analysis of the data obtained. As a result  of our studies, we didn’t find a relationship between gender and liver pathologies. In dogs, several changes were recorded in the liver at the same time. Pathological processes in the liver were observed  in 60 % of the studied  animals. The structure of pathological processes was as follows: 49% had dystrophic processes, 32% had cirrhosis, 20% had hepatitis, 15% had acute congestive hyperemia, 10% had neoplasms, 5% had toxic dystrophia. The peak of pathologies was noted at the age of 4 years (19%), 7 years (16 %), 5 years (14%). The main causes of pathological changes in the liver were high quality feeds, infectious diseases (distemper, piroplasmosis, infectious disease of unknown etiology), toxic substances, autointoxication, stress.
