I run a Home Boarding for dogs and the death rate of the normal tennis ball is "Tragic" The "Orbee" on the other hand has been abused daily by many....not only that watching them try to chew it is also really funny... The Tuff Tennis Ball is a winner. No Contest!
I have 2 collies who love balls! this is the only ball that bounces, floats and they can't chew up! Although on the pricey side is worth every penny. Even when the outer yellow layer wears off the white ball underneath is still as good. The dog web provides a quick and reliable service every time. would highly recommend balls and company!
