Only my big dogs are on shavings when they are out in the barn..
The fur babies have their 2 vets beds in corner of room, rest of room is newspaper on top of rubber matting on top of tiles.. I have found in past even textured tiles with paper on are slippery when wet.
Usually I have a crate in the corner of the whelping area to avoid mum squashing the babies but we are mumless now so taken crate out & added another vet bed
