It's a Bully Stick shaped like a ring! Dogs can't find the end of the stick, so these last longer than your average bully stick. Made from all-natural grass-fed beef pizzle. After your dog tries these, they'll be saying (or woofing) "put a ring on it"! 

From Red Barn: 

"all-natural, highly digestible chews are made from a single ingredient, beef pizzle (a muscle), and slow-roasted in their own juices for maximum flavor. But they do more than pack a powerful punch of flavor. They work overtime to support your dog’s muscle development, while the natural act of chewing helps support their Dental health by gently massaging their gums and scraping away plaque and tartar buildup. 

Our unique shapes — rings, springs, barbells, and tangles — spice up your dog’s chewing routine as they happily figure out how to wrap their mouth around their favorite shape. A genuinely delicious and nutritious boredom-busting chew!"
