Pet approved !!!! Our puppy immediately grabbed it by the straps and took off!! It is well made and has handled some serious chewing in the last 24 hours. We love the glow in the dark because puppy playtime does not stop when it gets dark out!! It came with a pump and was very easy to assemble and inflate. This toy would be great for a pet owner that struggles with grasp & grip strength, the straps are absolutely genius.
