I love the idea of the dogs not eating nylabone plastic so have been searching for "healthier" options that last for heavy chewers. Two German Sherpherds, they are not big fans of the circular shaped toy but love the antler shaped one and even with both chewing on it, has not been destroyed yet and is not cutting their gums open. I am not finding pieces laying in the carpet. Recommend this

My dog likes it!

Size: Medium, Color: Antler, Size: Medium, Color: Antler

My aggressive chewer loves it! I have a 20 pound rat terrier ....small was recommended, but we went with a medium. He went to work on it right away. He is not picky about chew bones but it makes me feel better that it is a natural material. The chewed photo is about 30 mins after giving it to him.

Not for us!

Size: Large, Color: Antler

I'm sure for a dog that doesn't chew, would be great. Ours went through it in days, leaving sharp shards and making his gums bleed.
