Answer:
What is it called when a cat wins a dog show?
To cross the water I'm the way. For water I'm above I touch it not and truth to say I neither swim nor move.
I am a sharp looking horse with a flaxen tail. The longer I run the shorter my tail becomes.
Upon your lonely journey I accompany you, whether you travel through endless mountains or seas of blue. Wherever you go, I keep your place. Lost you're not, when I'm embraced. What am I?
I have three heads. Cut off one I become stronger. Cut off two I become ten.
No matter how little or how much you use me, you change me every month.
