I used to think I could tell which Arabians had been gingered. (See mention of rule upthread). I then happened to buy my CraigsList purebred who carries his tail so that it looks like he’s been gingered every day of his life, walking to the pasture, at a standstill, under saddle at shows, you name it. A humbling moment for me, guess I’m not as smart as I thought! Somewhat embarrassing too.
Just another case in point to support @kirbydog The only definitive way to know if a horse has any medications in it is to test it.
Typical tail carriage. Guess I need to say that he hasn’t been gingered for the record. But in the old days I would have said a tail carriage like this couldn’t have been natural. Joke is on me!
