Lately I've been doing a bit more research on cab horses from the late 1800s to the mid 1900s, and have found that most carriages, cabs, etc. were drawn by larger draft horses such as Clydesdales and Shires. I will do a bit more research and see if I find either of them fitting. I will probably do some research on other breeds of draft horses as well.
I've started questioning Morab as opposed to just being an Arabian. I've felt that lately just labeling myself as an Arabian horse hasn't felt quite correct. I will probably do some more research on Morabs and I will probably look into other Arabian crossbreeds too.
