Doc doesn't like to walk through dewy grass in the mornings when I take him out in our front yard on the leash. I can stand in the middle of the yard and he will stay as far from me and as close to the gravel as the leash will let him! If he has no choice, and HAS to walk through the grass, he will get off it as soon as he can and immediately start cleaning his feet! After taking care of business outside in the backyard, he comes up on the deck and cleans his feet again. It's really cool, because we never have to worry about what Doc will track in! There's never ANY doggie paw prints on the floor here!
