Yes, do not make it too deep, or cold. Don't use a hair dryer on it it will burn it. But do dry it really good because small animals are very susceptible to colds.
the g pig knows what it wants--more than once a week is ok--put a little ladder so it can get out if it wishes or gets tired--ensure that there is a snug (insulated)wind-proof box available--no detergents--never leave it in exposed cage--you don't have to dry it unless it enjoys it
