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.

Not the least bit durable
Color: Blue
This is not durable! My pup had a hole in it in 5 minutes and a leg torn off in 3 days. He is not an aggressive chewer even....typically we have to replace toys because the squeaker has died, never because he tore it out!
