It is a game ball for dog, this has like a few strips that protrude from the surface of the ball, the material that we observe and we want to change the leather would be natural rubber resin which would provide an elastic texture that stimulates the dog chewing and greater durability of the product, the resin has to have some basic characteristics that already already has, as it is water resistant and carries the certificates

We want to put a device to sound with the movement, something simple but what we want is that the material is strong and resistant to the chewing of a medium large dog,

That is the problem when the dog plays with the ball, with the fangs punctures the valve inside and the ball is inulitized, we have to find a material either replacing the leather or putting a valve inside that is not punctured so easily, we had thought to put the rubber of the tennis balls inside the ball and that covers the leather to sew the nylon strips. How do you see it you could do it?
