Not for a dog that chews
Color: Black
The color tags came off so this was a chocking hazard for my blind dog. I ended up throwing away. My dog is not a destructive chewer.

My dog’s favorite toy
Color: Black
I’ve bought my dog 1 million different dog toys. This is his absolute favorite. I would highly recommend them. The handle makes it easy for the dog to grip.

This toy is awesome
Color: Black
This ball is awesome! We always have a hard time finding toys that last with our 100+ lb pitbull. He usually can shred a squeaky toy in less than a few hours depending on the material. But this one is still going Strong after him having full access to it for around 3 weeks. He just turned 3 and because he's a bigger boy it doesn't take him long to get tired, but he will play with it for a good 15 mins straight at any given time. Not only is the handle still in tact, it also still squeaks! I would definitely recommend this toy for super chewers.
