What is the gestation period for miniature schnauzer?

Generally, mini schnauzers would be under the same timeframe that all dogs are in their gestation time....which is between 61 and 64 days from mating. My own personal mini schnauzer had her first litter last November and she delivered 4 healthy pups on her 57th day. We were not expecting them so early, but all was fine and we are planning ahead with this next litter!
