Not Indestructible To My Dog. Do NOT recommend for aggressive chewers
My 11 month old Jack Russell Rat Terrier literally chews EVERYTHING. Finding toys for her other than the very few Kong extreme toys they make has been a real challenge. I bought this bone hoping that it would be atleast somewhat indestructible and that shed be able to chew on it for longer than 5 minutes. Well shes had it for about 15 minutes now and theres already a chunk missing so not to thrilled about that. Hopefully it will last atleast the rest of the day. I gave this product a 3 star review for a few reasons: One I would say this product would be great for a slight to moderate chewer but with my dogs pirana teeth and jaws of steel this bone has been no match for her. My dog chews and chews until theres the smallest piece of toy hanging off or an indent big enough for her to start ripping pieces off so this did not work for her. The product is also made nicely it is thick so no worries about teeth puncturing through it. I also liked that the ends are smooth so no worry of my dog eating it from the holes at the end because shes done tbat with many toys.

Best toy we’ve got.
Love this toy. I have had it for over a month now and there is not a bit of damage. I put her favorite soft treats in there and then break a milk bone and stuff it in there to make them stay, and it will keep her busy for hours(depending on how well I stuff it). So worth it. She is a blue healer/Rottweiler mix, very energetic and amazing at destroying toys, but this one, she is more focused on getting the treats than tearing it apart. Flawless design.

Good buy

A winner with our GSD. He’s not a super aggressive chewer but it has still held up and is a favorite.
