My dog hates the way this thing smells. She tries to play with it, but the scent is too strong for her nose. I know it's the scent because she usually sniffs it two or three times in between trying to grab it with her mouth. She treats it like an explosive in her mouth and quickly moves away after spitting it out. She used to have a bone that looked similar to this (same material) that was unscented and she gnawed the hell out of it. My sister's pitbull spent the night and chewed that toy into bits, leaving my Yorkie mourning the loss of her once treasured bone. Please make an UNSCENTED version of this toy!!!!

Worth the money for heavy chewers

Color: Brown-X

I finally found a dog chew that my puppy can't destroy in a half an hour or less. My puppy loves this, chews on it for hours and still holding up.

Holds up to a

Color: Brown-O

Bought this because of other positive reviews. It does hold up to an aggressive chewer but the pieces are sharp once it’s “broken in”. I bought the circular one as I figured that one would be less likely to break. It is still good after about 6 weeks.

My dog didn’t take to it, but yours might.

Color: Brown-O

This is a very durable toy that’s reasonably priced. For some reason, my dog didn’t take to it. It might be the round shape, but there’s nothing wrong with the product. The size is good for large dogs. My dog is 50 pounds and there’s a chance it was too big for him. I’m not sure. But I think if your dog has enjoyed other similar toys, this is a good buy.

Fun and practical for our power chewer

Color: Brown-O

Four paws up! It is great for chewing and for rolling in a fetch game. Our powerful chewer loves it!
