Off the top of my head, boxing, and the equestrian events.
In the last week or two there has been a huge controversy in the "horsemanship" world concerning a top trainer caught on video whipping a horse while laughing at it. If people treated other pets the way most people treat horses, they'd be arrested for animal cruelty. But for some reason (historical?), ancient, barbaric approaches to training horses are still predominant. And we have a mountain of evidence that demonstrates it's not necessary to use these cruel approaches.
