While this toy was super adorable and our 1 year old puppy loved it. The colors were bright and vivid, and it made fun wrinkling sounds he absolutely loved. However we were lucky if it lasted 20 minutes. Within minutes the crinkle paper was coming out and it basically fell apart, and he's not a destructive pup.

NOT for aggressive chewers.

Color: Blue, Color: Blue

Bruce had the stuffing out of this thing less than 5 minutes after handing it to him. This is not for aggressive chewers. Toys from the Dollar Tree have lasted longer than this thing. And now they want to charge me a buck to return it. I'll just let him finish shredding it. Maybe what's left will keep him entertained for a couple of hours.
