Thank you, klmccallum, for the welcome. I'm glad I caught your attention with an old thread
It does seem to be an eternal question. My two pups graze like cows, the little one even pauses in a game of fetch to lie down and have a snack. But a messy corgi bottom is a REALLY big annoyance. The springer spaniel at least can physically deal with it. Or cover it with his tail.
So, IS IT THE GRASS?
