How do you all handle the fur that grows out onto the bottom of the paw from between their toes? IN THE WINTER... i've heard i should keep it clipped short, or else water/ice/snow gets in that fur..... but don't dogs need that fur to keep their lil feet pads warm on the cold snow? so everybody does this, cut the fur short ? I been doing this, keeping it short, but now i'm wondering if Buddy might need that fur afterall on the bottom of his feet? or no?
