My puppy 🐶 loves this
Our puppy is teething and this toy is a perfect answer for her. The quality and material are wonderful.

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.

Not for super chewers
My doodle puppy chewed the rings off. Definitely not made for a super chewer

Ok for an aggressive chewer but not the best
Color: Pink
O Jane an aggressive chewer. This has held up ok. But she still occasionally gets pieces chewed off.
