    Great chew toy!
    We have a small dog who’s a BIG chewer. At 16 pounds, he goes through chew toys like a dog 4 times his size. This one is hands-down his favorite, the one he takes everywhere he goes. He spends several hours a day with it and after 3 months, he’s just now getting close to breaking it into two pieces. Our doggo will never be without one of these.

    great chew toy
    Bought this marrow bone for my great dane puppy and he loves it. hes had it for 3 weeks and its still in good shape. He takes it everywhere. I’d give 5 stars, but there is not a smaller size for my wifes teacup dog. You should make more sizes!
