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!
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.
