I've got years worth of The Morgan Horse sitting around here & I can flip through them and find plenty of homely headed Morgans--and no, not just on the poorly bred, "nobody" horses.
As I said before, all breeds have heads that do not fit the classic breed standard for that breed. As for Morgan's, the biggest disservice to the Show Morgan World was a horse called Noble Flair Now if you know anything about Morgan's, you will know this horse. He is registered a Morgan, but it is rather common knowledge that his sire was a Hackney horse and not a Morgan. Thus the UGLY head was introduced to the Morgan World. The breeder of this horse was one of the top breeders with the most money in the Morgan World and he was able to get away with cheating (at that time). Another top trainer and horse breeder did not. Again, if you know the Morgan World, you will know whom I am talking about. The introduction of DNA caught this breeder in a round about way, but not till after his"Morgan" won World Championship and a few years of his get being sold for over $100,000 apiece. Sad part with that one, is the horse really looked like a Morgan (as most often Morgan blood will produce a horse that looks like a Morgan) with a classical Morgan head. Noble Flair did not, and he had a butt ugly head!!
Many of the top performing Morgan's today have Noble Flair blood in them. Several of my horses did too and yes, some of mine did not have the classically beautiful Morgan head, which drove me nuts. My trainer kept telling me that a riding/driving Morgan does not win on its head.
There are two Morgan Magazines. One approached the horse show world with driving/ saddleseat and halter horses. The other catered to the more thick draft horse type Morgan This seems to be the type Morgan which is the one you are referring to, and many in that magazine did not have so classical a head. Since they were bred to be work horses, breeders did not care that they kept the classical Morgan head. Now I am not talking about the show western horses. Futurity French Command was a MAJOR drive behind the show western horse and his get have OUTSTANDING heads.
There are also a lot of poor quality Morgan's with nasty heads, especially those that are more the stocky kind used for cattle driving.
Since I bred for halter as well as Park, I had the more refined carriage type horses and most of my horses had pretty heads.
Still, I am a head freak and have to have horses with pretty heads, one of the reasons why I love my Minis so much. Most of mine have beautiful heads!! Another reason why I am not a pony fan, nor was I a Saddlebred fan because of their heads. And yes, Saddlebreds come from Morgan's but the head was lost along the way.
