It would be tight. But I'd bet on the QH. QHs have a record 57 mph, while most greyhounds have only 45 mph. No guarentee, though. The horse might trip, the dog get a short-cut, or te people organising the race tilt the finish line to the greyhound's side. ; ) : P
If it was a short race Thoroughbred would have won but the type of Thoroughbred matters.
Geryhound is a sprinter. Husky is a long haul dog. We all know a Greyhound would win up to maybe 5 km. After, it's the Husky's advantage.
A horse can reach speeds of 47 mph while a bear can only reach 25 mph. Overall the horse can run longer distances, especially over a bear. So the horse would probably win.
The Kentucky Derby is a horse race, you would win it on a horse, specifically a three year old Thoroughbred.
Win a race
This is the show horse. Win, place and show.
If I understand your question correctly, if only three horses race, would you win no matter what? You would only win if you bet on the winning horse to "win." When you bet on a horse race, you also bet on what position that horse finishes. You may bet on a horse to "win, place, or show" or all three (each bet costs more money). If the horse comes in first, second, or third, and you bet all three, you would still get a payout. There are numerous combinations to wagering, Exactas, Trifectas, etc. and even in a three horse race, if you didn't bet correctly, or on the right horse, you could still lose.
The farthest distance a race horse has come from behind to win is great. This horse went from last place to first place.
Well most dogs would win because the amount of dogs bred to swim while horses weren`t specifically bred to swim.
Not that I've heard of.
