The Ball
The GoughNuts Ball is not a chew toy but instead is an interactive toy. Yes the Ball is tough and we have made the first GoughNuts Ball in the strongest Black recipe. The Black is stronger and more durable than the Green. The GoughNuts Black incorporates the original GoughNuts green but then adds carbon technology to enhance strength. The GoughNuts Ball Black is guaranteed, as are all of the GoughNuts line of chew toys.
In addition to the GoughNuts two layered safety technology included in every GoughNuts toy, where 'red means stop!', the Ball is designed with a multi-axis groove system that may help the dog breathe in an emergency situation of throat Blockage. Spherical objects or balls can be a safety hazard for the reason of throat blockage. 
The GoughNuts Ball bounces well, floats, and we hope is a toy the dog will enjoy playing with. This is the first interactive toy, as the GoughNuts Ball is not designed as a chew toy. If the dog is left to chew it will attack the grooves and if you have a power chewer it will destroy GoughNuts Ball. Please stop at the red. We will replace the toy as described in our guarantee section however please realize that the Original GoughNut ring design remains the most durable chew toy.
Goughnuts Guarantee for life!
GoughNuts Guarantee - If your dog chews through the outside wear layer, Green or Black, to expose the red indication layer, GoughNuts will replace your toy. 
GoughNuts patent pending, "Chew Toy Safety Indicator" is a mechanism for the dog owner to see a clear indication of when to take the GoughNut from the dog.  See the "Chew Toy Safety Indicator" patent online - US Patent No. 20070289551.
Goughnuts lifetime guaranteeReturns Procedure - If you see a red indication, return the GoughNut to:
Tuff-toys-4-dogs, Mains of Forest, Memsie, Fraserburgh, Aberdeenshire, AB43 7AT.
Please include a cheque for £2.95 that covers the return of a new GoughNut back to you. We will evaluate the toy damage and return a new toy. This return or guarantee policy is one of our commitments to your dog's safety.
Please do not allow your dog to continue chewing the GoughNut if red is indicated. The red safety core is designed to give a clear indication to show when the toy is damaged and is an instruction to take the GoughNut away from the dog.
Following this instruction when you see the visible indication is a design feature to help prevent intestinal blockage. Intestinal blockage is a serious safety issue and in a worst case scenario can kill your dog. In general the chew toy is designed to withstand the aggressive chewing of your dog. However if the dog does manage to chew through to the safety indicator, it is time to return the GoughNut to us - your dog's safety is paramount.
The GoughNut is designed with diameters that are sized to make it difficult for your dog to destroy or damage the GoughNut.
It is important to know that manufacturing, like life is not perfect. Therefore whether a chew toy has a defect or your dog simply has the power to destroy a toy, as soon as the original design of the toy is compromised the toy must be taken away from the dog. This instruction will help keep your dog safe.
Any red indication is an indication to take the toy away. We will only congratulate you for taking the toy away when the smallest amount of red is present.
Many dog owners have followed our patent pending instruction showing us that the premise is working. Please make every effort to keep your dog safe.
Safety, Safety, Safety - We want your damaged GoughNut back. This is our investment into your dog's safety.
Every dog owner has the responsibility to check the toys that your dog is chewing. All toys should be taken away when damaged to help prevent blockage.
Correct sizing is as important as any safety feature. Choose a chew toy that is big in your dogs mouth. The chew toy should appear large in your dog's mouth. When you have a doubt about what size to choose, please ask a pet professional for help.
As a rule make sure the chew toy is larger in size than the distance between your dogs back molars when measuring across the jaw.
