Chew proof. Solid. She chews up other things less since she got this.Lasted as long as I expected considering my dogs sizeMy 9 mo old APBT loves this bone. Plus he hasn't destroyed it in the over a month since he's had it, which is almost unheard of for him! This is definitely worth the money!It tastes great! So now I don’t have to slaughter anyone to get the flavor of meaty bones, all I have to do is order from Amazon and get meaty tasty bones delivered to my door.Doggo likes it though she was able to damage it on day one. Still pretty durable and my pup likes it!The bone is very durable and my dog loves it. It’s been several months and he is still is excited to chew on it. The flavor also sticks around.Seems durable which is needed ( she chews hard!) but she’s not in love with it. Occasionally will choose it out of her toy basket. Was hopeful she’d love it.
