Your Experiences with Grooming Your Dog

Do any of you guys ever trim the hair between their pads on their feet? I can't remember what I heard about it, it makes their nails grow less fast perhaps? I think that's what I heard, although I'm not exactly sure why that would be. I know it can help them not slide around so much on hard surfaces. In the winter, it can help stop ice/snow from collecting on their feet too. I don't trim mine's often, she doesn't get too shaggy between her toes, but once in a while I trim it back a bit.
