Analysis of liver pathologies in stray dogs in the age aspect (sectional study)

Abstract

The presence of stray animals in megacities or small settlements is the result of human activity. Stray dogs are in direct contact with representatives of wild fauna, influencing the occurrence and spread of various epizootics and epidemics. Stray animals, as a part of society, can serve as a biological model for understanding the influence of the environment on the body. We conducted a sectional study of 32 dogs aged from 2 years to 10 years and older. As a result, it was found that there is no correlation between sex and liver pathologies. Liver pathologies in stray animals were observed in the period from 2 to 7 years old, with a peak at 6 years of age, by 8 years old the number of pathologies decreases almost 2–3 times. Liver cirrhosis (45%), protein dystrophy of the liver (45%), acute congestive hyperemia of the liver (19%), fatty liver dystrophy (16%) and neoplasms in the liver (13%) were recorded as often as possible in stray animals. The main causes of liver pathologies in stray animals were: stress, toxic effects of food or chemicals (poisoning), pathogens of infectious diseases, metabolic disorders, internal bleeding (car injury).
