Abstract

The aim of the study was to develop a methodological approach for predicting the approximate date of birth in female French bulldog dogs based on the results of morphometry. The object of the study were pregnant females (n=61) of various breeds. The results of the morphometric study showed that during the last 7 days of pregnancy, the parameters of the fetal skull diameter in the studied dog breeds (brachycephals and mesocephals) increased by 0,51±0,04 mm, which made it possible to more accurately determine the date and birth and plan a caesarean section. At the same time, in newborn puppies of brachycephalic breeds, the indicators of the biparietal diameter of the skull exceed those of the representatives of the mesocephalic group. The revealed anatomical features (parameters of the biparietal diameter of the skull, synostosis of the body of the sacral bone and the first caudal vertebra) in the French Bulldog breed do not allow determining the approximate date of birth using already developed formulas. In this regard, we have transformed and recommended for use the formula ((VRmm – 27,17) / 0,63) to determine the approximate date of birth in representatives of brachycephalic dog breeds.
