Seems to me, either a horse is thumping or
isn't Usually it is pretty obvious but can be subtle enough that if
the vet isn't paying close attention, he can miss it. I just can 't
imagine a vet mistakingly diagnosing thumps...either it is there or it isn't
and if it the horse is thumping, then there is some kind of problem
(electrolyte imbalance?) that needs to be addressed.
