This is the newf shack outside we use when pups are ready to go outside and start learning to potty train outside around 6 weeks old (depending weather). There is a big door and dog door for momma to teach them to go in and ourt to potty and it really helps with training for you. I get great reviews on how quickly they go to the door to potty. I tried to show the yard some to where they go out. We do not have the  wood box in there anymore as we only keep pups inside rooms to stay and out to play and learn house breaking.
These are older pictures and some of them have come down and room repainted often.To the right is our past newf Ty.
The wood box is no longer in the room , it's all open now.
To the right is the outside of the newfshack and it's attached to my house which goes out from my downstairs.and into the fenced yard.

Below left is our very first whelping room, which was our back basement and now just a picture room or a spare if ever needed for any reason.
My son's old room were turning into a puppy room
TV/video hook up so we can watch pups 24/7 in familyroom
