How Soon Can A Shih Tzu Get Pregnant?
Pregnancy in a dog lasts approximately 9 weeks, with an average of 63 days. This means that the first day of week 1 would be considered as the first day of pregnancy, where as the last day of week 63 would be the last day of pregnancy. A Shih Tzu can get pregnant as early as 8 weeks and as late as 13 weeks of age. It is important to note that the first day of the first week of pregnancy is considered as day one, and not the date of mating..
