Not for tough chewers
Color: Blue
Cute toy, good concept but definitely not for super chewer. Got it at such a price that I let him destroy it because he was having so much fun. You only have one birthday a year after all.

fun toy
Color: Orange
Very cute toy .My dog loves it. He is hard on toys and loves playing pully. So far it is holding up really well. It is a good size for medium to large dogs. I think if you have a small breed it may be to large. The color is a vivid orange and white. I really think your dog will love it.

Will buy again
Color: Orange, Color: Orange
This was one of the first toys I got my dog and he LOVED IT. I sadly had to throw it away because he peed on it but this is something I will definitely repurchase. Perfect for tug of war and playing fetch. Definitely not indestructible as he did rip it a little but it took him a LONG time to do that
