I previously rated this 5 star when I first purchased it a little over a year ago. We use it outdoors with another throw on top but always put it in a protected area when the dog isn't sleeping on it. He does not dig or chew on it. Over the last couple of months the fleece cover has started to deteriorate. We took it off to wash for the first time and were removing the other cover and the zipper broke. So now the memory foam is exposed. For the price, I would have liked it to be a bit sturdier.
