My gelding does this sometimes as well.. but only when he IS lazy. Just walking around.. when Im on him he doesnt.. but I did ask my farrier about it.. he said he djust does it when his toes are too long:P
Looking more at this picture and thinking about Barrel's response... I'm wondering if it has to do with foot length too. TWH's are positioned so they're sort of crouching a bit on the hind end, meaning they have to pick their feet up more dramatically to move their feet without hitting the ground. I'm not sure how to describe this, but it may be because he's too uphill and toes a little long? Still would like a video, hard to make a judgement like that on just 1 photo
I didn't hear him say anything about Kissing Spine. He is is flat shod all the way around. He doesnt trip alot he just drags them its like he's on his tippy toes vs actually sitting back on his toes when he walks. He is a 6 year old, no previous show history. I use him as a trail horse. Yes its fairly new. When I got him 2 years ago he wasn't doing it. The only thing that Im doing differently than what the previous owner does it I keep him in a stall.
Im posting the link to the video of him trotting. I can't upload it here because of the format.
