Very durable; aggressive chewer approves
Size: Jumbo, Style: Chicken
My dog is an extremely aggressive chewer so finding a toy that can survive more than a few days is never easy. This bone has done well for the last couple months. It’s a little bit larger and heavier than I was expecting but isn’t a problem for my German shepherd. It smells fine; at least it isn’t stinky. We play fetch and tug with this toy and there is very little wear and tear and only shows teeth marks. She will sit and chew on the toy for quite a while and seems content while chewing on it. Great tog

Helps With Teeth Cleaning
Size: Small, Style: Beef
Our dog loves chewing on this toy multiple times a day. I believe it helps with teeth cleaning. As we do not brush or add additives to water or food for teeth cleaning. Seems that vet is not suggesting to have teeth cleaned every visit anymore. The rubber is very durable. Last about 6 to 7 months before we start to see deterioration and have to replace.

My dog's favorite rubber toy
Size: Small, Style: Beef
One of my dog's favorite ever toys!! She is obsessed with everything playology but she never gets tired of the squeaky bones and the nubby bones. My only word of caution is to know your dog and if they're a big chewer be careful they dont eat pieces. She'll chew off chunks and spit them out.
