In my opinion, the bitch should be inside during pregnancy and weaning. Its important for socialisation that puppies are brought up in a house environment.
Since you are new to breeding, I would strongly urge you to change your mind and get your dogs neutered.
- What breed are you breeding?
- Do you expect to make profit?
- Do you have a lot of money prepared in case of emergency/complications?
- Are you prepared to lose your bitch if she dies giving birth?
- Are your dogs AKC registred and do you show them?
- How will you ensure they are going to good homes?
- Are you prepared to take every up you breed back if their new owners can't keep them?
