Well, I dont like using the commercial shiny sprays because they dry out the coat, but I figured out a pretty good recipe myself.. 2/3 apple cider vinegar and the other 1/3 split in half with baby oil and olive oil and put it in a spray bottle. All done! As a warning, oil attracts heat, so dont use if you live in a hot place in summer (or wash it off afterwards if you use it at a show). I spray it onto their coat and rub it in with a soft brush every 4 or so days and I also spray some on every other day (including the days it gets rubbed in). It doesnt make them AS shiny as Show Sheen, but its certainly much healthier and it makes their coat softer (and it lasts longer). You could add more parts baby/olive oil for more shine probably. Make sure you shake the bottle before spraying it on as the vinegar and oil seperates.
