After having guests for the holiday's we received a gift for our two dogs, a lab-pit mix and boxer-pit mix. It was a Bumi and like every other toy we thought it was nice and would be destroyed in a matter hours if not minutes. Boy were we wrong! Three months later they are still tugging and chewing on it. They have been able to get through the ends and I felt it was time for some new toys. As I went on the web site I saw a picture of two dogs playing with the Tux. That picture is identical to my dogs trying to play with the same tennis ball. So I ordered a new Bumi and a Tux. They love them! Summer is here and they run around the pool and drop them in and the best part is "they float" so they can retrieve them not me! I wouldn't waste my time or money on any other toy - Thank you
