The dark horse was beautiful.
I walked around the horse's stable.
longshot, dark horse
the night was dark for the moon was young.
My horse trainer counted my horse's strides.
It is describing the horse. It is a drinking horse. The verb in that sentence is the word "is".
I mucked out the horse's stall.
"As i went outside to take out the trash, everything was dark."
the horse neighed pleasantly
the cat was spritely in the dark

It looks to be a pale horse...You look pale.
I put the harness on the horse.
