Abstract
The measurement of gestational sac diameter (GSD) and biparietal diameter
(BPD) using ultrasonography (USG) remained fairly accurate determinants of gestational
age (GA) in canines during early and later stages of gestation with precision of ±1 to ± 2
days. The present study looked at the possibility of placental thickness (PT) as a
determinant of GA using USG in normal pregnancies of different breeds and body sizes
and then to correlate the same with reported gestational age (RGA). A cross sectional
observational study was conducted on 90 pregnant dogs of different breeds and parity and
a total of 112 observations were made by using ALOKA PRO SOUND α-6 ultra sound
unit using 5 MHz convex probe.
