Little bit. If it happens to dry somewhat while he's still out, it brushes right out of his coat. Otherwise he gets carried (at arms length) straight to the sink to be rinsed off.
But either way, until his next bath with the whitening stuff ... he's just not quite his normal snow-white. More like a West Highland Cream Terrier.
WHY do normally white-white-snow-white dogs seem to LOVE mud, rolling in grass, etc? <sigh>
