Hi - pets at home do a super anti-chew dog bed (and the covers to go with it). I was sceptical when I bought one for our little Sam who managed to chew through kitchen stools, chairs, table legs, computer desks, dog beds, dog toys etc........... however.......... he never ever had a chew at this dog bed!!!! - not even the cover!!!!! They will do a money back guarantee and so that is why I bought one because I thought I had nothing to lose. Unfortunately Sam has gone, but the bed is still here in one piece!!! Look on their website for them - they're a bit pricey but cheaper in the long run I guess!!
