Following the finals, all horses sent for drug and tail testing will also have their necks palpated, flexed and thermographically imaged for the second time by a licensed veterinarian.
First off we do not have quarter horses but have at times be subjected to having horses being drug tested by state vets at shows, usually no big deal but after having been accused of switching horses for a test we chipped all of ours for positive ID.
If you are showing I suggest you also microchip register your horse (I see the AQHA has a pilot program now).

We had a near knock down drag out battle with a state vet who was at a show to take radium and test all champions. One of our bay mares he insisted we had switch horses on him…even though he had personally escorted the horse after winning a championship from the ring to the stall. The vet insisted the horse on the registration papers was not the horse before him (he was going by physical condition saying the mare could not be 18 but was no more than 8)
Had to get the show’s organizer to come to the stall to vouch for the horse as they personally knew the horse.
After all, all Bays look alike was his reasoning
