He could be a Quarter Pony. Or a POA cross (solid).
I really don't see Welsh in him at all, though I'm not super familiar with Welshes. Most of the Welsh crosses I've seen seem to always end up with that Arab-like baby doll head and he does not have that, at all.
He could also be the product of something like a Shetland/mini and a QH, or a similar sort of cross. A very small horse mixed with an average sized one generally ends up around that height...
I see no Welsh in him at all. Maybe a QH cross or a cross of several breeds. Cute little fellow. He looks a bit sad though. Maybe some really good conditioning would help. Too bad about his scar. Someone didn't take good care of this little fellow.
Nope he aws being passed from home to home, a woman originally rescued him for her 3 year old and 8 month old kids. She was going to break him while they were napping, but she couldn't do it. So she gave him to her friend, where her 8 year old son was going to break him but he gave up after 3 days. And that lady listed him as free, just come and get him. So we drove 3 hours to get him and get him here, and going to work on saddle training. The previous lady had only threw ropes across his back and put saddle pads on his back. And had said he'd NEVER had a saddle on. Well I certainly believe her now. We popped one on him and once we tightened it up he flew into bucking around. Once we got him calmed down, we lunged him some to make sure all the goofies were out. And then we just lightly pressed on the stirrups some which he didnn't like. And then unsaddled him and let him back out to pasture. He's a sweet little guy just no one has worked with him. I think he'd made a great little english jumping pony
