Holly used to need a potty patch, before we figured out that fish doesn't agree with her. Now, I may have to do a little minor cleaning once every 6 weeks or so. Not bad enough to make it worth taking her to the vet or groomer to get shaved. Usually by the time I see it, it's dry and I just comb it out.
This past summer I was over the neighbors and I get a call from my mother "come home, your daughter has poopy pants and you need to clean her up". I figure it was the normal couple of strands of fur coated in poop. Boy was I wrong, she looked like her butt exploded. What a mess! She wasn't happy about it, but right into the sink she went. Apparently the new treats I gave her the night before didn't agree with her....
