1. Morgans are, indeed, naturally gaited as has been stated. Sorry to oppose Guilherme, but I was raised in NE Ohio where the Morgan horse was held in highest regard by the old timers, both as a work horse and a saddle horse.
There are "sorry horses" in every breed, I don't care which one is being discussed and that is generally the fault of the breeder or caregiver.
There weren't too many breeders and serious Morgan folks often went into New York to buy them; paying enough for one, to buy two or three well bred Quarter Horses (back in my youthful days).
Thankfully there are breeders out there, trying to preserver the gait, rather than think they can breed the gene out, like so many trotting Morgan breeders have tried to do. Gaited Morgans aka Naturally Gaited Morgans
Just like there are breeders trying to preserve the naturally gaited Appaloosas that perform the TRUE Indian Shuffle, not an Appy that's been crossed with a Tennessee Walker.
2. Do your Walking Horse history and you will know the Foundation Mare of Record for the Tennessee Walker is a black MORGAN mare by the name of Maggie Marshall. She is great great grand daughter to the famous Figure, a/k/a "Justin Morgan Had A Horse".
If you look at my avatar, you should be able to see why that TWH got mistaken for a Morgan more than once in his life. Only being 14.3H added to some folks confusion.
Maggie Marshall is allegedly well documented as having seven gaits. Ivory Pal
Where it says in part:
the horse chosen as the foundation stallion of the Tennessee Walking Horse breed was ALLAN. Foaled in 1866, his sire was ALLENDORF, of elite Standardbred breeding, and his dam was MAGGIE MARSHALL, a documented seven-gaited, great-great granddaughter of FIGURE, the original Morgan horse.
Google "gaited Morgans" and more hits will come up than you have time to read:)
Yes the signature gait of a gaited Morgan is the Singlefoot. Way back in the early 1960's my granddad had a Morgan/cross mare that was a beautiful single footer.
I'll give my post about three followups before an argument ensues. Anything about Walking Horses seems to elicit beyond heated debates. Guilherme couldn't even talk about his saddle find without someone starting an argument over it
