We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!

Great chew toy

Color: Blue

I bought this almost a year go. My dog is still chewing on it! Nothing last this long with her. She is a 100lb Rottweiler that is a strong chewer.

Well loved

Color: Blue, Color: Blue

We just got this sweet girl from the shelter a few days ago. She's had this toy for 2 days and already chomped off one of the legs. She does have other toys so she doesn't play with this one all the time but she does like it a lot! It's very hard and durable on the ends. But as you can see, it's not indestructible. She carries this little guy around the house like they're BFFs. It's super adorable.

Durable and a favorite toy

My 7 month old Black Lab loves this bone. She is a chewer and has gone to town on the three ends. They are roughed up a bit but holding up better than expected. Highly recommend for dogs that love to chew.

Perfect for aggressive chewers

I have a 2 year old pittie and she chows thru bones in minutes, even those reviewed as "long lasting". This thing is still going strong after 9 months. She was not initially interested, had to spread peanut butter on one end, one time, and now it is her go-to chew toy. Looks a little mangled after all this time but she's not even 75% thru it. Highly recommend, no stomach issues.
