Abstract

Results revealed that presence of small intermediate cells, Parabasal cells, Large intermediate cells, Neutrophil and Superfacial cornified cells in vaginal smear during pregnancy in the bitch. The initial detection of the extra-fetal and fetal structures was by ultrasonography revealed that the anechogenic spherical gestational sac compared with the hyperechoic uterus was first detected on Day 17 in both breeds. The yolk sac membrane was first detected as an echogenic U-shaped fetal membrane in a range of 24-25 days. The embryo appearance was on Day 21 of pregnancy. For estimating gestational age and predicting parturition date by sonography, GSD was measured from day 20 to day 38 after the last breeding and HD was measured from day 40 to parturition day.
