Various cardiovascular diseases led to enlarged right side of the heart which resulted in the enlargement of caudal vena cava (CVC). CVC size could be best studied by evaluating the CVC/AOD ratio. Rajapalayam and Chippiparai dogs are the important indigenous breeds of Tamil Nadu. The present study was designed to develop basic data on the diameter of caudal vena cava and descending aorta in these indigenous breeds using Radiography. The study was carried out in young (1-6 months) and adult (> 6 months) dogs. In the present study, mean ± SE of CVC/AOD were found to be 0.87 ± 0.0 and 0.93 ± 0.04; 0.77 ± 0.06 and 0.92 ± 0.03 in young and adult age group of Rajapalayam and Chippiparai dogs respectively. The study indicated that body weight didn't have an influence on CVC/AOD ratio.
