Hey I recently got a Peruvian Paso/Arabian cross gelding with a little head LOL.
He has more of an arabian shaped head, none of my average horse head stalls are small enough, so I don't know if I need a pony size?
I measured with bailing twine from one corner of his mouth around his ears and to the other corner of his mouth and it was about 41 inches.
I will most likely get a western style headstall even though I ride english I am just going to trail ride him and western are usually cheaper.
Any advise is apreciated
(I attached some pictures of his head so you can see the shape also he is large pony sized/ 14hh if that has any effect)
