I appreciate all the replies! Keep them coming, lol. I know as a child we had many dogs that had puppies (my father thought vets were a waste of money, so no one was spayed or neutered. Very sad I know
) And we never had issues. So when I got Misty and Molly I was totally surprised when they started fighting. I know had they both been spayed it may have never have occurred and will not make that mistake again. I guess one step at a time. Right now I will just pray for a healthy litter, continue to research and ask my vet and trainer. So thank you to everyone that replied.
