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!

Adorable but not Durable
Color: Blue
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.
