I first bought the Zisc for my border collie and she did not care for it as much as her plastic discs but my Shiba Inu puppy LOVES it!! Later I bought my puppy a Hurley because she's a chewer and she could not destroy it. Finally, I bought the Bumi so the two could play tug-a-way together which they did a bit but then my pup chewed right through it. I definitely recommend the Hurley for chewers.
