Admit it: you’ve looked at your grey and compared him to George Lucas’s AT-AT Walker. And you’ve probably seen the commercial with a greyhound dressed up as one. (Note to self: find this costume on eBay). With those lanky long legs, sometimes our greys find themselves struggling to get a foothold on the slippery hardwood floors. Add some age and arthritis to the mix, and it’s a catastrophe waiting to happen.
