Query: A ball made for dogs!

I've just ordered a second lot of these balls, but only because we lost the other ones. They've been worked on full time by a lab and a very determined vizsla for months, without even showing a mark. Any tennis ball they'd have stripped and popped within a few minutes, suppose that's why they call them tennis balls, not dog balls...They fly far, bounce well, don't break windows if the throw is a bit off-target (unlike the Kongs) and the dogs absolutely love them!What a great product!!! I don't think 5 bucks a pop is over the top for a solid dog toy, you definitely get what you pay for!We've disposed of all other balls (or their remains rather) and will certainly try out other products from ChuckIt. Very happy! :)
