well you could use a bellie band on him but that tends to mat the coat, I would try raping the hair on each side of the coat in 2 sections when you take him out to potty, the show beeders here can show you how or take a look at salliesyorkshires.com click on the grooming button it shows you how to rap them, a hair scunche or a hair clip could be used to pen both sides up on his back when you take him to potty, you can bath him more often as well like once a week, but remeber to condition the coat well just like your on hair, a good leave in conditioner well work well too, Hope this helps Denise good? ans post by the way.
