Surprisingly Tough Chew Toy for Aggressive Chewers
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
This chew toy is made from a very hard nylon style material and feels substantially tougher than the average dog toy. It definitely seems geared toward aggressive chewers and larger dogs that destroy softer toys quickly. Our pup immediately liked it, especially with the peanut butter groove feature, which helped keep them interested longer. The toy feels almost indestructible during normal chewing sessions and has held up very well so far with no major gouges, cracks, or chunks coming off. Based on first impressions, I would expect this to last at least a month or more for many dogs, which is far better than a lot of chew toys in this price range. Another nice bonus is that it is dishwasher safe, making cleanup easy after using peanut butter or other treats in the groove. As for the teeth cleaning claim, I honestly cannot comment much on that yet. I have not personally noticed any obvious difference in our dog’s teeth or dental condition from using it. Still, as a durable boredom relief chew toy for aggressive chewers, it has been a solid performer so far and seems like a good value.

My dog approves
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
My dog absolutely loves these flavored chew bones! She’s a very aggressive chewer, and this toy has held up really well to her constant chewing. It keeps her entertained for a long time and seems to be one of her favorite toys. I also love the unique scorpion shape. Living in the desert, we see scorpions pretty often, so I thought it was a funny and fitting design. While I don’t expect it to turn her into a scorpion hunter, it definitely adds a fun touch! The flavor keeps her interested, and the durable material makes it a great option for heavy chewers. Overall, a great toy that has been a huge hit with my pup. Will definitely be purchasing more!

Cheaper than shoes!
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
Instant hit with a dog that likes chewing shoes! This is a much cheaper alternative than a new pair of shoes. They state it is indestructible but at the same time the directions state when it reaches a certain chewed up point to take it away. So obviously this is destructible but it does allow for a lot of chewing. I can not personally attest to the flavor but it must be good because the dog wanted this chew before i even unwrapped it. It is somewhat ugly in both color and shape but I have had no complaints from the dog! I also appreciate that this can be put in the dishwasher to clean. To be honest i have never considered that with other toys and I do appreciate that it can be placed in the dishwasher. Most importantly, this lasts, the dog is in love with this, there are multiple limbs for the dog to chew. It’s his new favorite toy and worth every bit of the cost!

Durable
Size: Medium & Large, Color: Red Scorpion
This bone has proved to be durable and tasty (per our Labrador). She chews and chews with barely a dent. I’m guessing the flavor is good because it’s still her go-to bone after almost a week. Beware of your pet dropping it on your toes though as it is quite hard.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!
