Hey, I'm Grin and I shall be reviewing.
You have a few spelling mistakes in here, I won't run through them now but if you run them through a spellchecker you should pick them up.
Also! The punctuation seems to really break this up, which makes it more difficult to read. This poem's about horses, right, so it might give a stronger feel of the physical shape, the movement, etc., if you cut down on that - this is what we call enjambment.
Your rhyming's a little forced, so remember that great poetry doesn't have to rhyme. In this case, it's limiting what you can do.
However, you have a great rhythm here and I really enjoyed the poem. With a little work, this will be great. Well done.

EDIT: if there's something you missed in your original post, rather than adding a second you can hit "Edit" at the top of your post. That will be useful if you want to change spellings, content etc.
