Drill brush. Go in the same directions you would with a regular brush. Have someone hold the tail, or put a sock over it. Make sure you do inside and out of the legs. Spray and comb in whatever sheen you use first of course. If you want to do it wet too, I suggest using a rice root drill brush just for that. You can do this all over their body (NOT bellies) once they get used to it. Go slow, don't get the hair wrapped.
