Below is a test comparison between our GoughNut Black and our Original GoughNut Green. Please understand that regardless of how strong any chew toy is made, certain dogs will chew through it. Therefore, our two layered patent pending safety design is incorpoporated in our GoughNuts Black. The two layered patent pending design gives a clear indication when the Goughnut Black turns color from Black to Red it is time to take the GoughNut Black away from your dog. Every GoughNut toy is guaranteed and when any red is seen, this indicates that the diameters of the toy are damaged. Please read the entire patent online to understand the details of our two layered patent pending design.
Please note that the The Original GoughNut has a cross section of 1.75". Physical properties shown below are measured in PSI or pounds per square inch.
The test results shown follow ASTM methods D412, D2240, & D624 (seen in sections 9.01 & 9.02)
GoughNuts Green GoughNuts Black
Tensile 3500 PSI 3800 PSI
Tear Die C 140 PSI 180 PSI
Hardness 43 48
The GoughNuts Black properties are higher. The hardness will hold your dogs jaw open more than the Green taking leverages away that lessen the dog's power. The higher tear strength and tensile strength testing show the GoughNut Black increase in physical properties.
Our goal is safety. The additional of carbon technology incorporated with the GoughNuts base recipe allows for the additional strength of the GoughNut Black. Please adhere to the two layered patent pending technology. Please take your GoughNut away if your dog can chew through the Black or Green layer to expose the Red.
