I’d be curious to hear why you think he looks more miserable in the water video (I assume the second ride video?) than the first ride. I agree he looks NQR but his demeanor in general looks somewhat improved to my eye over the first video. He’s definitely not thrilled with the right lead canter in the latter half of the video, but does settle somewhat towards the end. He’s generally fussy in his canter departs which again, in hindsight we recognize as a symptom but it’s not uncommon for green horses coming into work. Overall he looks fairly keen. Not comfortable, but not worse than the first video. He’s very unhappy in the first video to my eye.
Admittedly I’m watching them on a phone so maybe I’m missing something. Overall though I see a fairly linear improvement in what is shown in the videos from Ride 1 to the last video available.
I agree that this presentation is seen all too often in horses of many disciplines and levels of experience. I’ve seen quite a few nice young warmbloods who present like these videos for their first rides. Some improve and some don’t. I see some very pissy horses when I scribe at dressage shows, too. It can be really hard to parse out what is pain, what is learned behavior, what is stress-induced, etc.
