Unless a dog is badly neglected and allowed to become so stained a bath won't shift most of any discolouration it doesn't have to be unnaturally persil white for pity's sake. A surface rub over with a damp chamois (I use hypoallergenic baby wipes) should take care of any surface dirt like a bit of mud spatter on show day.
My friends dogs are often a little pink from the soil on Exmoor where they are exercised more than most, Yet a Bath a few days before major show (not every show) is enough to keep them the right colour (grey with pale legs and underside).
We stayed there for several wet days on a field and still manged to have acceptably clean dogs for Birmingham, and they were last bathed before staying there a month earlier.
Have to admit it is much easier to keep my lot clean in town and if I don't go with them wallowing in the country pink mud then they only need a bath a couple of times a year, and I hate to say ti but the water runs cleaner off them on a rinse than it does when I wash my hair once a week.
Dogs that are bathed, in my opinion too frequently, attract the dirt like magnets and it then becomes a vicious cycle and they keep having to be bathed.
Interestingly enough the American authority on our breed, in which country products and over grooming/trimming seem to be king, raved over the coat textures of our dogs, yet the bloodlines on show were often those she was familiar with at home.
