Holds up against my velociraptor! Much better than some of the other holey balls that get torn apart quickly. I think this is a great idea to reuse old shoe soles into toys for the heavy chewers like heelers. I would like to see a large ball like 10-12 inch diameter, so they can push and throw it around.

Molly loves her ball!

Color: Blue Helix, Size: Large

Soft and easily caught by a rambunctious Border Collie. She loves her ball and points to it with her nose when she's ready for another game of "ball". Easy to throw and easy to clean of slobbers!
