So I am finding out. I have heard of it with some birds, fish, frogs and some farm animals, but never knew it held true with dogs and cats. I did hear of it when they used artificial insemination, but not from natural mating.

It can happen w any animal in fact . I had a goat even who had two babies of 2 different breeds , 2 different fathers . I also know of fraternal human twins with 2 different fathers , they did DNA testing . It can happen.

I know that different male dogs can mate with the same female, but only one will actually be the father. I have not seen any clinical research that says a female dog can get pregnant twice in the same heat cycle. There are fish and frogs that can do that and even certain species of birds, but I never read that dogs can.
