I bathe Dudley once a week too
. First it's in the pool to play, he loves his raft. Once he's wet (from pool) i use John Mitchell shampoo/cond. Rise with the garden hose set on shower nozzle. After he's rinsed he loves to sit in the hot sun and "rub ir out", i comb him out several times and he's done. Sometime i spray HASK on him if there are mats in his coat.
He does love the hair dryer too, but the summer time in FL, he'd rather be outside with all of this, he says so...
