Perfect for Aggressive Chewers
Color: Blue-Green-Orange
I've been looking for toys my German Shepherd puppies can't tear apart or chew into little bits within minutes. These are tough enough to stand up to them and have the added benefit of helping their teeth with the little surface nubs. This is the second set I've purchased - not because the puppies destroyed them, but because they needed a set for inside as well as outside. I HIGHLY recommend these toys if your dog is a destruction machine!!

Durable, sensory texture
Color: Blue-Green-Orange
These are fantastic. They are durable and high quality. My dog loves the sensory texture and they satisfy his aggressive chewing. I've bought other high-end, popular brands and he chewed through it in less than two hours. I would definitely buy these again (if I even had to)!

Best purchase
Color: Blue-Green-Orange
These are by far one of the best toys for my aggressive chewer. My pitbull mix loves the football & ball, gave the other toy to my niece's dog. Bought them in Nov/Dec and they have held up great, still look new. I was upset when I saw they are no longer available. I would have purchased more to have some for specific outdoor use.
