It's an early morning when Applejack hears whining and whimpering coming from the barn. Once inside, she sees Winona but with a litter of ten puppies at her side. Applejack is stunned, surprised, and a little bit shocked. How on earth did Winona have puppies as there's no other dog on the farm?
Only "sex" is a dog giving birth to a litter of puppies. Don't get your doggy toys in a twist.
