I have a friend who breeds Min Pins. When my girl got pregnant for the first time I called him and asked several questions.
The main thing he stated was that almost like clockwork his females went into labor on the 63rd day. So I counted the days and sure enough my girl had her pups on the 63rd day.
Shes pregnant again now and believe me, im counting her due date for the 63rd. day. Hope this helps.
