I bought a hurley and a zisc a few months back for my year and a half old chocolate lab, who can, and will, destroy every toy I bring into my house. That was until I found an article in a magazine aboutWest Paw Design, and figured, why not try'em. After about 6 months and tons of playtime, my lab and new lab/border collie mix puppy have yet to destroy these toys. I LOVE THEM! They have so much fun and the toys last. THANK YOU SO MUCH FOR MAKING TOYS MY DOGS CAN ENJOY AND NOT CHEW UP!!!
