Abstract

The objective of this study was to determine the gestational age by obtaining fetal measurements and observation of organogenesis using the ultrasound method, in canine females that were in a state of gestation. The study was conducted on 15 dogs (Canis lupus familiaris), who had an average weight of 10 kg, and who attended a gynecological consultation at the Cruz Verde Veterinary Center, located in the City of Quito-Ecuador. Each of the patients underwent the respective anamnesis, physical evaluation and to deduce a diagnosis of gestational age the ultrasound study was performed. The ultrasound method allowed to diagnose, that of 15 females reviewed, 14 showed signs of gestation and 1 of it, apparently empty, but that in the end it was a false negative, because gesture one brood that developed normally. The duration of gestation was 64 ± 2 days and the correlation between the number of gestational vesicles and the number of puppies born was 0.89 (P<0.0001) and the heartbeat were found, after day 28 of gestation. In addition, it was possible to recommend obstetric surgical intervention (cesarean section) in 4 of the 14 (28.6%) diagnosed pregnant dogs by virtue of the fact that their physiological state indicated risks of life, either for the mother or the puppies.
