My Sophie is a Saluki - German Shepherd mix and is an avid chewer. No toy has lasted more than 15 minutes with her.
The Hurley was given to her by my dad from his trip to Canada a year ago. She has been UNABLE to destroy it. No matter what she does, no amount of chewing has managed to puncture the toy.
I am so amazed it has lasted this long with her and has sustained no doggie damage at all!
