Actually my dogs do not roll in anything stinky. Taggart does the scoot around on his back thing, but never in something stinky. The only times I've dealt with stink on my dogs is when they met a skunk (twice for Zoee and once for Taggart).

Now my moms dogs............they do this ALL the time. And my parents live out in the country so there is plenty of stinky stuff to find. That's pretty much how they get regular baths is by rolling in stank.
