Can you put a baby gate across the opening or some kind of baracade....a sheet of plywood? If those pups aren't raised in the house, close to vaccums, rattling of pots and pans, TV, people walking in and out of their enclosure, very frequent handling, voices, kids, adults, other dogs near by, they'll have a real problem with shyness when they are older. Shy dogs often become biting dogs and then they get euthanized. It's extremely important to begin the socialization process immediately and continue when the new families get them.
The breeder of my Doberman kept a crate in the kitchen (vinyl flooring) and a baby gate across to keep the other Dobermans and another breed...I think it was an aussie mix out. She'd be in there cooking and stepping over them, washing the floor with all these puppies scrambling over her, climbing on her back (when they were a little older...about 8 weeks) and she'd be talking to them in her rather loud voice. Her neighbor kids would come over and play with them. There were people coming in and out. Of course, she was careful to make sure they washed their hands before handling and taking shoes off outside first until they had their first shots I think. Anyhow...not to be a nag, but this is one of those things I'm passionate about and really concerns me.
This crate is right in her kitchen. The puppies are getting socialized or accustomed to a crate at the same time as giving them a secure place to rest. She left the door off.
It all just makes for a good head start during a very, very critical period.
