My dogs spend a lot of time outside, and they get dirty as a result. I can wash them, but they are dirty again the next day. Since you are aren't supposed to wash a dog more than once a month (messes up the oil in their fur or something), they are always pretty dirty.

I don't mind the dirt that much, but there is the embarrassing problem of visitors. When someone comes over, the always want to pet the dogs. But after they do, they are left with a visibly dirty hand. The shame!

To solve this problem, I've found that baby wipes make a great quick wash for the dogs. When company is coming over, you just give the dogs a quick wipe down with the baby wipes, and they are at least clean on the surface.
