Where do people buy those peanut shaped balancing objects used to help condition their sport dogs? Any recommendations? Are some shapes/brands better than others? I'd rather buy one in person rather than pay for shipping, but I'm not sure if there's a place in the Toronto area that sells them. I'm totally clueless and haven't looked into buying one before, but I'd like to start using one with Cohen. Any help is greatly appreciated! E: I wanted to add I'm more interested in using the item for strength training than body-awareness. Does that make a difference?
