Has anyone had anything to do with string halt in a pony? At first i thought he'd foundered again but it's different to founder this time.
Stringhalt is a condition that presents with involuntary flexion of one or both hind limbs. It is a neurological condition that may be caused by ingestion of toxic plants. If it does not resolve on its own when the suspected toxin is removed from the diet then a surgical procedure may be successful in many cases. It is best to consult your veterinarian regarding diagnosis and possible treatments.
