Suggestion? Yes! You cannot beat a cow mat!! They can be clawed but takes some gouging, they are warm to lie on and good for young or old bones, shock absorbing! My friend has a couple of dogs that shred bedding, she has cut cow mats to fit in all her dogs kennels/crates now. Those that shred don't get bedding, those that do get bedding, though they're warm to lie on, even with no bedding in.
http://www.mayomats.com/index2.htmYou can get them from farm supplies. They're warm to the touch, can hose them down, have a non-slip surface, easy to cut with a stanley knife. In fact I'm so sold on them I've got a piece to go in my!
I think they're around £35 for a 6' x 4' piece.
