I am a very wild dog and until I got my very own Zogoflex Hurley bone, I destroyed every floating toy used in our daily swimming play sessions.  I have had my Hurley bone for two months and despite chomping, tugging, and tearing, it is as good as new.  My "human" is ordering a smaller version for my little buddy Tink.  These INDESTRUCTABLE toys are THE BEST.  They get "5 paws" from us!!!  Guinness and Tink.
