I use the 'ol kitchen sink. I recently had a new one put in and made sure it had the spray attachment included. Piece of cake that way.
I use shampoo with Coal Tar to keep the coat moist and shiny.
I lather him up, hose him down, take him to the bathtub to skake off, then return to the sink to blow dry.
We have the routine down so tight the whole proceedure only takes about 15 minutes.
Gotta love Yorkie hair. It cleans and drys quickly and easily.
