These things are amazing! They last forever even with dogs that can destroy nearly everything else in mins! I ordered these as a doggie Xmas gift over TWO YEARS AGO, and they are still pretty much fully intact! They chew on them all the time, too!(see pics; that's over two years of steady use!) I only got the one 4 pack, and have 4 dogs, too! Since making them so well does kind of reduce my ability to buy many more from them, I feel I should at least let people know they really are crazy durable and dogs love them! I will prob buy another 4 pack soon, just so they are easier to find(end up under couches,etc). Def a good buy!!!!

Built for heavy chewers and actually holds up

Size: Medium, Style: Fishbone/Wishbone

This chew toy is a total win for heavy chewers and has held up really well compared to so many others we’ve tried. It keeps dogs busy for long stretches and they stay genuinely interested in it instead of destroying it in minutes. The shape makes it easy for them to grip and chew comfortably, which adds to how much they use it. The durability is the real standout here, making it one of those rare toys that actually earns a repurchase. The material feels sturdy, it’s easy to clean, and there’s no noticeable odor, which is always a plus.

Definitely recommend

Size: Large, Style: 4 Pack

My dogs absolutely love these! I bought them at a great price! They have lasted my dogs over a year! I have a full pitbull, pit/lab, pit/boxer, and a pit/mastiff. So needless to say they pass the power jaw test. They look just like the pictures and they are pretty light weight!
