Accord- ing to the results, female dogs showed abdominal circumference increment and mammogenesis from a month post-mating to parturition and lactated before parturi- tion. 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. Hu- man early pregnancy test strips can not be used for pregnancy diagnosis in female dogs. Currently, ultrasonic method is the most accurate method to diagnose preg- nancy in female dogs, and the optimal diagnosis time is the 30th d post-mating. External observation and blood routine examination can be used as auxiliary methods to diagnose pregnancy in female dogs.展开更多
