Interesting background to add here: the agent I bought Carolina from, when pressed about her papers, said "Oh you could probably register her with the Oldenburg Registry after having her assessed." Odd, since she's supposedly Dutch Warmblood/TB Cross.
I found a video of a bay mare Oldenburg mare (I didn't search for Oldenburg), that looked EXACTLY like Carolina, trotting, cantering and broncing around the pasture and she moved EXACTLY like Carolina does.
So.. I messaged the poster of the video, and I'm hoping I hear something from them. Because that would just be amazing! Of course that person apparently hasn't logged into youtube in over six months but stranger things have happened right?
Cross your fingers for me???
