Dogs will be dogs. And some dogs just like to get dirty. My lab, Bailey, will find a tennis ball anywhere in a 1/2 mile radius. Chip will find a mud puddle anywhere in the park -and get as muddy as possible. He will actually try to immerse himself into the puddle further.... To get the most benefit of the mud bath treatment, I assume. If you saw the kiddie pool incident this summer (http://www.youtube.com/watch?v=-kr5UC8B2Tg), think kiddie pool in the mud. I truly do try to avoid these kind of activities, but when he high-tails is to the mud puddle and does this, I have to at least catch a picture before I drag him out of it and blast him with a hose.
