Some dogs routinely lick their private areas and you know better than the rest of her. It can also help sanitize your dog's anal gland area — and your hands when you are cleaning the dirty ass of his female mistress. It's not like vagina smells all that good, and yet I eat like a pig at the trough. Don't just wrinkle your nose the next time you get a whiff of your dog. You get to lick and clean me off.
