Came apart.
Color: Cherries
We were playing with it and the green part pulled off of the red part. I'm pretty sure that is not supposed to happen. I took the green part away from the dog because that part is too small for my pup to play with. But we continue to play with the red part. My dog likes the texture and the bounciness.

Caution - handle comes off!
Color: Cherries
I really liked this toy when I opened package--our dog liked as well! Until a short time ago when I saw her chewing on the green "stem"! The stem had come apart from the main cherries. This is a small enough part that I think she or any bigger dog could choke on. Our dog is a small lab. Would not recommend buying.

Must buy!
Color: Grape
My dogs love this and so do I. It really smells like “fun grape” like a fun smelling marker. It’s gentle for their teeth and durable! They are both interested in it and take turns using it, pretty awesome!
