Abstract
Liver disease in dogs can develop as a result ofmany different insults. A clinical study was conducted
on clinical cases presented to the Small Animal Medicine Referral Clinic of Madras Veterinary College
from 2010-2012. Cases presented with signs such as anorexia, lethargy, ascites, icterus, pigmented urine and
vomiting were screened for liver disorders. Out of 23,289 dogs with gastrointestinal disorders, 100 dogs were
found to have liver diseases of different kinds. Ultrasonography of liver was taken for diagnostic assessments.
Liver Disease Group, was further subdivided into three groups; Biliary tract disorders, Parenchymal disorders
and Neoplastic disorders. The liver was imaged using 3.5 MHz or 5.0 MHz transducer. The selection of
frequency was based on the body size of the animal i.e. lower frequency transducer was selected for bigger
body size. The incidence of liver disease was found to be 0.15 per cent of dogs in the hospital population
and formed 0.43 per cent of gastrointestinal caseloads of the hospital. Non-descript dogs and the age group
of 4-8 years were commonly affected. Dogs less than 4 years were also found to be affected with a higher
incidence, but requires further studies to ascertain breed predisposition of nondescripts and assessment of
risk factors such as infectious or toxic agents. Higher prevalence of biliary disorders in males and nondescript
dogs also Warrants studies on breed predisposition and on risk factors. Ultrasound was found to be very useful
in the diagnosis of canine liver disease and strategic interpretation of the results can be effectively used for
identifying the canine liver disease and type of liver disease in majority of the cases. 3D ultrasound imaging
was found to have superior diagnostic yield, especially to visualize the exact location of the lesions/ changes
involved in the liver diseases.
