GoughNuts Original Ring is our flagship chew toy first designed in 2006. There was a need for a safer product and there was a need for tougher or more durable product. The Original Ring design has no weak points. The dog will grab the Ring in a different spot each time creating months and or years of power chewing. It all started in our kitchen with an idea of "Green means Go and Red means Stop." The safety premise is that if your dog can chew though to the red indicating layer, your instruction is to take the product away. All GoughNuts have a safety Guarantee that we feel and we know is changing chew toy technology around the world. The GoughNut Original ring is tough, bounces, rolls, floats (except for Pro 50 models), and whatever else you can think of. If you are new to GoughNuts please know that we believe you. You may have "THAT" dog. We have heard it all. Our goal has always been to make chew toy products that can be safe for every dog. We have a wide range of product with a goal of matching your dog's power and persistence. Whether you have a "grinder", a "picker" or a dog with a massive power jaw, we have a GoughNuts Ring for you. Please trust the fact that we realize that there is no such thing as an indestructible chew toy. Our goal is safety. Our products are known throughout the world for durability and our safety indicator is making chew toys safer to help eliminate possible blockage issues. The original GoughNuts toy was designed to address the simple but serious issue of SAFETY. The GoughNuts chew toys are designed knowing that safety and fun go hand in hand. Each GoughNuts pet toy has included in it's design the GoughNuts patented safety indicator where Green means "GoughNuts" and Red means "Stop".
