My dog loves chewing on everything but this. and he's a puppy! when it was delivered to our house, i thought shadow would chew it all up right away, but he didn't! that is why i named it a miracle bed, because it was a mircle he didn't start chewing it up. and then one day he was sleeping upstairs on the couch, so the door to downstairs was open since he was sleeping. i was just watching him sleep and all of a sudden he woke up! he went downstairs so i followed him cause i thought he was going to the laundry room, but he didn't. he was going to his kennel to get his bed! then he went back upstairs with it and automatically put it down in front of the couch and started sleeping on it right away.that bed is making my dog change his personality completely.it sure is a miracle bed.
