I have used non slip for a long time now esp in the whelping box eliminating the need for newspaper under vetbed and so no smell of pee. Also ideal for toilet training pups in crate as no movement or for dogs who have had ops.
I get mine from s and c supplies who go to all the shows
http://www.dogproductsdirect.com Very happy with quality and find it stays non slip for at least 12 months. John will also send it at short notice if needed and has even managed to do me an order for vet bed whilst he has been away at a show so brilliant service.
