Comparisons of Methods for Pregnancy Diagnosis in Female Poodles

In this study,five 2- 4 years old healthy female poodles were selected and mated after spontaneous estrus for pregnancy diagnosis with external observation,human chorionic gonadotropin colloidal gold rapid test strips( human early pregnancy test strips),ultrasonic diagnosis and blood routine examination. According to the results,female dogs showed abdominal circumference increment and mammogenesis from a month post-mating to parturition and lactated before parturition. At 5,6,7,15,25 and 35 d post-mating,pregnancy diagnosis with human chorionic gonadotropin colloidal gold rapid test strips showed negative results. Human early pregnancy test strips can not be used for pregnancy diagnosis in female dogs. Currently,ultrasonic method is the most accurate method to diagnose pregnancy in female dogs,and the optimal diagnosis time is the 30 th d post-mating. External observation and blood routine examination can be used as auxiliary methods to diagnose pregnancy in female dogs.
