Does anyone have advice about snow boots - I am hoping for taller ones if possible to give as much protection as possible - our town's name translated means "people of the snow" and we're supposed to gets a lot this year. I've heard of a brand called Sherpa that looks good but I'm not sure about the sizing - oh, and I can't go into a pet store to try anything on as we don't have one in our town. Thanks for any and all advice - Mabel and Darwin thank you in advance as well!
