A coworker of mine shows on the QH circuit. She has told me the tails are tested at the in-gate, someone pokes the horse with a pin or something to see if it reacts. There are vets who specialize in horses that compete on this show circuit who inject the tail with just the right about of some numbing agent to keep the horse from swishing its tail in class, but not so numb that it won’t react when poked with a pin or whatever.
Coworker (I do NOT consider her a friend, even though she thinks we have a horsey connection) was getting ready for a big class and her trainer poked her horse’s tail to be sure it would react. Apparently the vet had overdone it because the tail was dead still. Coworker and trainer were in a panic because there are also rules about scratching right before a class starts, I think she said the tail gets tested anyway if they scratch too close the class time and they could dq’d from the show. So same vet that does the tail injections also fakes some paperwork saying he was treating the horse for colic and it couldn’t show that day.
Big relief! says coworker, so matter of fact about the whole situation, as if she isn’t actually cheating. It’s apparently so common place on that circuit that in her mind it’s no different from hock injections.
