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

I shared my beef with him. He played balls with me. He was very friendly to my family, but when strangers approached me, you would see his fierce face. Time flies. He spent all his life with me.展开更多
