Our goals remain the same in that we want to provide the safest possible products that are durable and fun. The rubber is the same recipe as used on our rings but we have marked the outside with red to show that here is NOT a safety indicator in this product (as again it is for interactive play versus constant chewing). In the case of the Tug we are trying to protect the person as well as the dog.
There are 2 sizes of GoughNut Tugs:
Original Tug - 9 x 5 inches in diameter, 1.375 inches cross section
Tug MaXX - 11 x 6 inches in diameter, 1.5 inches CS
