Ik for sure that her mother was a racking horse I've seen her and the previous owners(the people who had her before the lady I got her from) raise show jumping horses, my vet said something about her having thoroughbred in her awhile ago. I don't care what she is its just im selling her and the girl was wondering what she was
She is really at an awkward age for conformation judgment and breed guessing. Wait until she is over four and put some pics up then. I second the person who said Hackney, maybe, if her front end develops a little more. It would explain the height, color, and some other things. But horses are incredibly awkward looking at her age, they can look totally different in a couple of years.
