Most of you are wrong which is so baffling. The count is actually a cremello (or albino if rockstar wants to call it that) Arabian, if it were based off a real life horse, which red dead horses are indeed based off of real horse breeds. Google image cremello arabian. If you compare the white Arabian to the Count, they are exactly the same besides the white Arabian has black around its eyes and such, and has a more white hue than a golden one. You are fooled to think that Dutch actually has a white Arabian until you take a closer look and realize that this Arabian coat is unobtainable in game. Someone said the horse looked similar to Buell. Buell is a different breed of horse for he is stockier and taller, but he is also a cremello horse. His horse is indeed definitely not a Morgan. Dutch is the leader of a gang, so rockstar wants him to have the best horse. Morgan’s are the lowest ranking horse that you can buy, and Arabians are the best in story mode.
He is not a Nokota because nokotas are basically miniature draft horses, they are very short and stocky, while the count is small and slender like an arabian.
He is also not a Dutch warmblood because Dutch warmblood are very tall and slender like thoroughbreds and Standardbreds, and the count is a short horse like an arabian.
(I’m passionate about this because I really like horses in general and I pay attention to real life horse breeds and also the red dead horses. One of the biggest reasons I play this game is because of the horses lol)
