Ten healthy puppies (five males and five females) were used to establish the regular echodopplercardiography profile during the neonatal period (from one to 30 days) utilizing Doppler (pulsed-wave and color flow). Mitral, tricuspid, aortic and pulmonary blood flows were measured. Positive correlations of all the measures, with body weight and age of the puppies for both sexes were observed. No differences in the cardiac development between male and female during the neonatal phase were observed.
