This is the first chew toy that Ruby has not been able to destroy (other than the hard nylon ones that get sharp jagged bits and are uncomfortable to hold). From the moment she got Happy Harold she ran around with it and wouldn't let it go. She took it to bed (the squeaking was a bit relentless to begin with but she's eased off with that) and at some stage she buried her 'treasure' in the garden. But she soon retrieved it and its now her favourite toy. I'm so impressed with Happy Harold I have bought another one to give to my son's puppy who is a destructive chewer.
