Hi!! I have a male and female shih Tzu. Wnderful dogs they are. Well my female has been in heat and this morning my 2 locked together. If she got pregnant this is the only litter I plan on having as I am not a breeder and honestly do not believe in breeding more than 1 or 2 times. Anyway, I marked on my calendar that they did the deed, also looking on the internet for info marked 21 days to feel my females belly for pups, also marked the calendar for the possible due date. I would like to know how soon after they did the deed should I take her to the vet to see for sure about a pregnancy? Do most shih Tzus just have their puppies on their own with no help? I also read on here about not letting them breed more than one or 2 times so should I now seperate my male and female? I take very good care of my dogs just want to be on the safe side for everything. Any ifo would be greatly appreciated!!
