I take a couple of Handi-Wipes (disposable kitchen towels from the supermarket) to rub down my dog if he's wet and/or muddy. If he isn't wet, I comb him just before bedtime to get rid of some of the excess hair (he sheds perpetually) and any creepy-crawlies that may be on his fur. This also allows us to bond a little at the end of the day. Needless to say, Hysson carries the Handi-Wipes and his comb in his pack! I also keep him in camp or on leash after dinner so he doesn't get into water or mud just before bedtime. As a result, he's usually relatively clean when he goes into the tent. That's a good thing, because he's part of my sleep system--a marvelous foot-warmer!
