It is a good idea to build a whelping box well in advance so the bitch has time to get used to it. 最好预先为母犬建一个产箱,这样,母犬可以有时间去适应。
Always keep a record of the date, the day of the cycle the bitch was bred, the results of the30-day pregnancy ultrasound or test results, the date of whelping, and the number of pups. 时刻记录相关数据:母犬配种的日期、怀孕30天超声波检查结果或是测试结果、分娩的日期、产下幼犬的数量。
