  • Eco-Friendly Accents: Woven exterior accents and comfort pads are made from recycled polyester, blending style with sustainability.

Great product
Size: Large
I was hesitant about buying this product, but I'm so glad I did. My dog (who is a very aggressive chewer) absolutely loves this toy. He will spend hours chewing on this toy. He carries it around the house and will show it off to anyone who visits. Since getting this toy for him, he has stopped chewing up other toys and focuses his chewing and destructive chewing on this toy. He has not managed to destroy this toy as of a month of chewing.

Great buy for an extreme chewer
