We bought this dog bed as the first bed for our 5 month old puppy. I thought this bed would be destroyed within a few days as puppies do what puppies do. To my amazement, this dog bed is very well made and puppy shark teeth proof. Seriously, our puppy tries his best to chew, pull, dig and destroy his new bed. He hasn’t succeeded yet almost four weeks later. The bed still looks as good as when it arrived from Amazon. Attached photo shows our exhausted puppy taking a rest 😀
