We just got a new horse at our barn who we are having some concerns about. The lady who got her did a trade and has 30 days to return her and get her horse back. We had just got done lunging this mare when we noticed her lifting her back legs up really high. Our vet says it's either stringhalt or EPM. He is going to come look at her tomorrow. Does anybody have experience with stringhalt? That's what we think it is. Although I also think it could be stress-induced EPM due to the fact that she is underweight and symptoms started shortly after a 7 hour trailer ride, the longest she had ever been hauled.
