Does the Sheath the Covers a Dog's Flaccid Wang Have a Name?

[HeyHomie]

You know how when a dog is sporting red rocket you can see his pinkish dong emerge from that little furry sheath that normally hides it? What's that sheath called?

[kayaker]

Prepuce.

foreskin?

In horses, it's called a penis sheath.
Rather unimaginative, but clearly descriptive.

It's clearly visible on buffalo nickels (http://en.wikipedia.org/wiki/Buffalo_nickel), as has been noted here before. (http://boards.straightdope.com/sdmb/showthread.php?t=354643)
