Yes, progesterone can be supplemented if needed in pregnant female dogs. However, this should only be done in close cooperation with your veterinarian, and only if progesterone testing shows that supplementation is needed - giving it when it isn't necessary can cause birth defects in the puppies, and may also throw off the timing of whelping if you're unsure of her exact due date.
