Good buy
Size: 6 in, Color: Blue
A winner with our GSD. He’s not a super aggressive chewer but it has still held up and is a favorite.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.

My dog doesn't like it
Size: 5 in, Color: Orange
My dog wasn't a fan of this at all. He was curious about it, probably because he could smell it, but he wasn't sure about chewing it.
It could be because his teeth squeak against it? Or maybe it has an odd texture? I don't know
But this has sat in the toy bin untouched since the day we got it

Great Chew Toy for Daily Play
Size: 6 in, Color: Blue, Size: 6 in, Color: Blue
My dog absolutely loves this toy. From the first moment he grabbed it, he wouldn’t stop playing with it. He chews on it, runs around with it, and even sleeps with it sometimes. What I like most is how durable it is — even with constant biting, pulling, and chewing, it hasn’t broken or shown any damage. The material feels strong but still safe for him to chew. The texture also seems to keep him entertained because it massages his gums while he plays. It’s lightweight, easy for him to carry, and the shape makes it fun for both chewing and tossing. This toy has become one of his favorites, and I’m really happy with the quality. I would definitely recommend it for dogs who love to chew.
