Something weird with the back - I can't tell what's going on there. I don't think it's a chiro issue or anything like that, it's surely conformation. Super high tail set, over a the knee, built uphill, pigeon toed, . I don't like her hip. I can't tell you why exactly, something just looks off about it. It's probably because she's not up to prime weight and condition yet.
Roach backed. That's the biggest issue I see with her. Otherwise she's a pretty cute little mare. Her neck ties in a little low, but that's not going to effect her very much. Her hip is a little steep too - but it could be the angle of the camera. Some of her with her head up and without a saddle would be better.
I've got a lovely bunch of Neuticals,
There they are all standing in a row
Big ones, small ones, some as big as your head
