He's at least a TWH cross, if not a straight up, short TWH. We had many of TWHs in the stable where I grew up and worked, and his head and conformation look just like them. None of the ones I knew were particularly tall; a few were close to 16 H, but quite a few were closer to 15 H. They give the illusion of being taller because their heads are set high. Many TWHs trot as well as gait.
He looks small for a TWH because he's definitely underweight.
Yea that's another thing he just never keeps his weight up. They have tried many things and nothing seems to get him to gain weight but the vet says he's healthy and everything is fine so I guess he will just always look like that.
Yea I think the tallest TWH I saw was my horse Harley he was about 15hh and I haven't seen a taller one yet although I know they exist lol. I just don't think this one is full walker.
Oh and the breast collar my friend got from horsetown I think. That's all her stuff because that's her horse not mine.
There are 2 TW in the barn across from mine. When I asked if they were crossed with something, the owner said, "nope, just tall for the breed". They stand about 16 hh, or there abouts, and your baby looks more TW than they do. I wouldn't be surprised if there is no cross in there at all.
