whose penis is cleaner, a human's or a dog's?

Question

I know that dog saliva is much cleaner than human's. I need help on my health class. please give details.

Answer 1

A dogs. It air dries, and is licked clean. Doesn't have a chance for over-growth of bacteria, so probably it is more hygienic.

Answer 2

This is a silly question but I would have to say a dogs because a dog is always licking themselves all day long and it is known by books that a dogs mouth is cleaner than humans.
