Both of our pups have Organic Bumper Beds, but our Golden Retriever is going through a chewing phase and has worn out the corners of both center pillows. We replaced one of the pillows, but haven't replaced the second as of yet; before we replace two $50 covers, we'll wait for the chewing to stop. Adding denim or some type of reinforcement to the corners would be appreciated. Otherwise, the quality of the beds are definitely first-rate and both pups (1 1/2 years old) love sleeping on them!
