That's me, that's not one of the Mearas - if you get this reference, you are a true Lord of The Rings fans just as my human, she loves fantasy and Tolkien is one of her favorite authors -, it's not Rocinante, Bavieca, or Bucefalus - again, if you get this reference you are a true reader and literary enthusiast.
I love running despite my defective hips (every great dane and most likely every big dog has them, at least according to my human. She is not a veterinarian but she knows her way around dogs, she's had dogs her whole life and enjoys reading about animals in general - and despite the fact that I get tired very fast, and then I can't walk for the rest of the evening.
I don't remember what I was doing on this picture, but my human enjoys throwing me the ball so I can fetch it, it's one of the activities we do together and I think she enjoys it as much as I do.
Look at my ears, my focused gaze, my active and ready for action stance, I am truly a majestic horse-dog.
