For years I did the dog in the bath trick. We installed a hose with a noozle and washed away. One thing I found to be really handy was one of those exfolliating gloves. When rubbing the coat, it helped the water to get into the coat. I poured the shampoo onto the glove and I got a really nice lather and also found that not as much shampoo was used. It worked for me anyway.....
