Ok, I found a couple of other links to the Frederic Remington sculptures

Now I will try to answer a few questions
First YLL, Don't mares and stallions have the same # of teeth?
Horses have small stomachs which is why they can't handle large amounts of grain.
True or False #1 is False, a horse should be cooled down after a workout before offering a small amount of water.
True or False #2 I think is True.

Luka,
#1) Is it when changing direction in the ring that you need to be on the incorrect diagonal?
#2) The mane falls to the right side so it is out of the way when tacking up the bridle(doing the buckles). I have known a couple of horses whose manes refuse to stay on the right!
#3)I am guessing that the whip is carried on the outside because in English riding the crop is carried on the outside.
