If you want another neat fact, all Racing Throughbreds (as in will race, not just exist or breed) have lip tattoos in the US. Can't speak for other countries. I could've researched my mare's but she was being uppity and I didn't want to mess with her mouth for long periods of time.

Oh and if it wasn't obvious, the race horse industry is extremely serious.
