The correlation between fetal and extra-fetal structures with the prediction of the day before delivery (PAD) in miniature dog breeds was evaluated. In the experiment, he used 12 female dogs, with body weight between 3kg to 5kg. Biparietal diameter (DBP), thoracic diameter (DTX), abdominal diameter (DAB), cranial caudal length (CCC), diameter of the internal chorionic cavity (DCI) and thickness of the placenta (EP) were measured using ultrasonography. from the 15th day after the last ride. Evaluated the simple correlations and the significance of the simple linear regression coefficients and the determination coefficient (R), with a significance level set at p<0.05. Among the parameters evaluated, DBP, DTX, DAB and CCC were those that showed the highest correlation with gestational time, and can be used to predict the day before delivery in miniature female dogs.
