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.

Best long-lasting dog chew

If you want something to occupy your dog that's harmless, this is the one. He doesn't have to chase it, so it doesn't get lost under the cabinets, and he's been chewing it for hours and barely made a mark on it. When he's chewing on this, he's not whining or asking to sit on my lap, and he can stay nearby as he enjoys this toy.
