Ok. I will take a stab at it. Even though I am a complete amateur also. I think it is called "cow hocked" in the back as it looks like her leg comes down at an inward angle from the hip to the hock and then outward from the hock to the hoof. The front does not look as drastic but it looks like she is toeing out in the front. I am guessing her but she has Egyptian in her as her chest is very narrow. Have you tried corrective shoeing on her to see if the farrier can bring her somewhat back in line?
Yes she is cow hocked, as far as her forelegs, it is the one that does the weird twist below the knee. We have yet to try corrective shoeing as at this point. It will be one of our next steps, this is the rescue mare we had picked up recently. I have no knowledge of what her bloodlines are, I've been told that she could be 1/2 Standardbred.
