I haven't looked at him lip, but there is no tattoo on the neck or anything like that. I will check his lip tomorrow before we go for a ride. I wouldn't call his hip bones 'protruding' but he does seem to have a prominent hip bone. I will try to get better pictures of him so maybe you can take a look at him yourself and see what you think.
When he walkes, he has a very long stride. So much that when I ride him, my hips move very much. More than any horse I have ever rode. And he has a more of a pace gait than a 4 beat TWH gait. I will try to get a video too for you to take a look at. He isn't very good at staying in his gait, but we are working on that. :)
