Mother dog moving puppies

Question
Our bullmastiff recently gave birth to a litter of 9 puppies but one was stillborn and 2 died because their body temperature wouldn't increase. We crossed her with our male neapolitan mastiff. At first she was very protective and wouldn't leave their side but now she seems to constantly want to be away fom them. We have them in a small room with a pen built around the outside of it. The other day she dug a hole right under the house and tried to move them there, she had only moved one by the time i heard it screaming and moved it back, we think the father may have gone into the room and disrupted her. We started locking her in the pen but that didn't work out well, she now tries to get out all the time and has dug a hole in their and moves them into the hole where they get covered in dirt and slightly buried. So we have been frantically running backwards and fowards letting her in and out of the pen when she barks and making sure she doesnt bury them alive! what can we do about this problem? the puppies are almost a week old and i hate hearing that high pitched screaming noise they make when she has their heads in her mouth and it looks horrible too. is there any way that we can stop the problem of her wanting to move them? we have work tomorrow and cant be running in and out of the house to let her in and out of the pen and cant lock her in the room in the pen because it becomes very messy.

Answer
Hi Leigh. You may have to keep dad completely away from mom and pups. He may be making her nervous. Some first time moms are really nervous like this, there's really not much you can do. You can make her 'den' quiet and keep all dogs away from her, you can praise her when she nurses them and treats them gently. Don't let any people come by to see them. However, some dog's just don't make good moms. If she doesn't stop this behavior, you will have to take them from her and hand raise them yourself. This means feeding/pooping every 3 hours, 24/7. You may have to take some time off of work to do this. If that's not possible, you'll have to find someone that can come to your house and feed them every three hours for you. If I can help with anything else, let me know.
