I was so excited about this bed. I thought it would see my pup through his young years to his old ones, but he has destroyed it. Even when "tuckered out" from lots of exercise, he still found energy to rip up his bed. He was able to open the zipper and shred the bed within the cover. Unfortunately, I could not trust him to be alone with this expensive purchase.
Overall, I think this bed is great, but I would think twice about getting it for a puppy until you are sure the puppy is old enough not to destroy it.
