To get horses to run faster, why don't they have a giant lump of sugar on a track ahead. Like greyhound hare

Dogs don't have riders. Dogs love to stop and chat. Greyhounds love to run, but they don't particularly care about going in the same direction as everyone else, and an itch behind the ear is more important than running around acting stupid. The fake hare gets them to run, and all in the same direction because dogs have an instinctive need to chase hares. Horses also would stand around if they could, and even if they decided to run it wouldn't be at the same time or in the same direction. But they have riders. What they don't have is any particular interest in chasing anything. But they love to get away from whips.

What would make you run faster? A sugar cube hanging by a string from the visor of your baseball cap? Or some one smashing your @$$ with a whip every two or three strides you take?

Dogs are predators so their natural instinct would be to run after something to eat. Horses are prey so running after something would not be instinctive. Horses naturally run fast especially when the horses around them are also running. Once they have been trained they understand that they should run to get to the front.

wow thats all i have to say o and also sugar really isent that good for horses and they want the race horses to be in shape so...

Cause it would to long to change the image of the industry. Horses are a symbol of doing a job that gives the best value to man and the horse. A horse should have more of desire to run than to run after a lump of sugar. Maybe also cause, dogs hunt, and horses work. So it makes more sense to have the dog chase a rabbit. Luckily for us, its a rabbit and not a cat. lol :)

because not all horses like sugar and it gives an unfair advantage to those who do.

They use a rabbit for the dogs this is very silly question horses will run fast because thats what they where bred for
