Thunder (our four legged grandson) loves this; as a matter of fact we are going to buy a second one so he has one downstairs and one on the bedroom level.  It is comfy for him and  he does not chew it; I think I will get the larger size for upstairs in case he has a toy or so as a bedmate (smiles).  Seriously, this is a great product and so easy  to zip off and wash.
