When these toys first arrived and I opened the box I was disappointed. They seemed a bit flimsy and were not what I was expecting Boy was I wrong! My dog lived his new toy and it’s has not left his side. Best of all, it’s a tough little toy that can take a beating and keep going. My dog usually tears through his toys in a matter of hours, and I tried numerous toys over the years. I’ve tried Kevlar toys, toy that claim to be very sturdy, he always destroyed them in a matter of hours. This toy looks flimsy, but it’s soft and strong

Dog toy that lasts.

Size: 5 Pack

I've got a heavy chewer on my hands, so I've basically thrown money away on countless "durable" toys that get shredded in minutes. I was skeptical about these, but the "no stuffing" design caught my eye—at least there wouldn't be fluff all over my living room! I'm happy to report that these have actually lasted! My dog loves shaking them around and making them squeak. The crinkle sound is a huge bonus; it really keeps him engaged. The fact that they're lightweight makes them perfect for a game of fetch, and my dog can easily carry them around. For the price, getting a whole bundle of these is a great deal. If you're tired of cleaning up toy stuffing, I'd definitely recommend giving these a try.

Not for aggressive dogs but no stuffing is super!

Size: 5 Pack

I've bought these several times but have the attitude that toys are disposable. One of my hounds will drop right through then to pull out the squeaker before losing interest. My other hound wants to love them. Glad there is no stuffing to get all over the house but they will tear quickly.
