Well, besides being a tradition, it sure helps cut down on the mud being tracked into the house. That's the main reason I do it. I sometimes find ticks in between the toes when the hair gets long. Short hair makes it easier to see if there are thorns or other things.
Also the only sweat glands a dog has are on the bottom of it's feet, so I suppose it could help keep them cool.
Does that help?
