I am a cow, but I'm not white or black.
I have 2 legs in front but no legs in back.
Look at my back end, you'll see it is round.
For long periods of time I can stay off the ground.

What am I?

(In reply to A gruesome guess by amadeus)

I think you might be wrong..If it was cut in half, you'd think the back end would be flat, right?
