I own a Thuringer aswell
my googling when i got her didnt find me much at all sadly. She is a beautiful mare and everyone falls for her instantly, i'll have to post a pic of mine later on, do you have a pic of yours?
I live in Thuringia. The Thuringian Warmblood (now German Sporthorse) is like any other Warmblood bred with the same bloodlines as the others and with the same lines in their pedigrees. It is just like all other Warmbloods in Germany that have the names of their region as Breed. Oldenburg, Hanoverian, Holsteiner, Bavarian, Sachsen, Rhinelander, Sachsen-Anhalt, Brandenburg, Thuringian etc etc.
