Holds up pretty well.
Color: Green Helix, Size: Medium
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!

Great Strong Chew Toy but not too Hard
Color: Red Pulse, Size: Medium
Great strong chew toy. It's very strong and does not tear apart like everything else. At the same time it is not hard plastic like the last brown one I ordered that could break my dog's teeth. My dog is a 2 yr old 14 lb Chi mix with a super strong bite. He tore all the stuffies up and even the nylon toy that was supposed to withstand a lot. This is the one toy that could outsmart him. I play fetch with him and it has a nice weird hop due it's shape so it keeps him interested and surprised. It's a bit heavier than other similar toys and I'm guessing bigger dogs would definitely like it too. I'm very pleased after buying so many others that were easily chewed up or too hard.
