Love Barkbox!
Color: Comet - Small, Size: Small
I can't recommend Barkbox Super Chewer dog toys enough for those that have a pet that loves to chew. They are durable!!

This is an awesome product and affordably priced! I'll buy more in the future!
Color: Comet - Small, Size: Small
This is a great ball for my dog Polly! It doesn't stink or have any weird oils on the ball. It is definitely durable. It has a nice chirping sound and it's great exercise for my dog's jaws. It's not too bouncy and it's the perfect weight that she feels satisfied having in her mouth and when she catches it in mid-air. It's not too heavy that I have to worry about it knocking her teeth out. I almost cancelled the order after I found out the size of the ball, I thought it was a larger ball that Bark makes. It turns out it is larger than a tennis ball which is what I wanted. Someone gave us a black, knobby, ball that is 12.5 inches in diameter and she absolutely loves it, it's her favorite ball. It's the perfect size for her American Pit Bull mouth! I cannot find this product anywhere or a comparable alternative that's the same size. If you know where I can purchase another ball that I've described @ 12.5 in. diameter, please let me know! I'll likely buy this ball that was just delivered, today, in the future, if it's not discontinued! It's a great deal for only $14.99!! Thanks from a happy satisfied customer, V.B.

Only ball he has not destroyed in minutes!!! So good that I purchased a second one for travel. It keeps him busy and tires him out because he cannot break it!😆

Sort of good for tough chewers??
Color: Deep Roots Carrot - Small, Size: Small Dog
The actual carrot part (orange part) is tough chewer approved and my dog loves. It’s basically the same shape and size as his kong. However the leaves (green part) is not tough chewer approved. He ripped ALL those leaves off and ate them within 5 minutes of me giving him the toy. However they passed through him fine.

Aggressive chewer puppy approved
Color: Cinamutt Roll - Large, Size: Large
My aggressive chewer puppy loves this. It is pretty sturdy. He hasn't destroyed it yet and he's had it for over 3 months now.
