Zangersheides are getting more common, they are elite jumpers but are actually more of a group than a breed in its own right I think. Just because sire and dam are Z's doesn't mean the foal will be a Z and vice versa. I own a Zangersheide who's mainly Holstein, the only Z in him is his great, great grandsire, Alme Z.
I knew an Auxois at one point, sadly I lost contact a few years ago. She was very quick and light on her feet for her size though I remember.
A girl at our yard owns a Zangersheide, Pitaque Z.
You couldn't pay me to get on that. From the Pilot lines.. complete and utter nutter. She dislocated her shoulder on him after he bolted in the school three weeks ago. Never seen such a big horse pick up so much speed in such a small area.
Some of our local breeds that might be unheard of in the States -
Latvian Draft - almost extinct now.
Latvian harness horse -
Latvian Warmblood -
I have a light draft type Latvian Warmblood/Harness horse, and the Warmblood and the Harness horse are the most popular breeds around here. Some breeders are also trying to restore the Latgalian trotter, but I didn't manage to find any pictures.
