This is not a safe indestructible toy
DO NOT BUY! My 22 lb doodle destroyed this within the hour. He had all the nubs of two of the rings completely chewed off and was chewing them like gum. He is only 9 months old.

Super cute! Really quiet chewer.
Super cute and durable for our boxer puppy, it is for sure puppy sized. Super light so he can still toss it around and I like that it doesn’t have any plastic smell to it.
