in a way. the back legs support the horse and boost him off the ground to run. So yes. If the horse did not have back legs he would not be able to run.
Mainly your legs and arms because you use your arms to keep pulling the rains on a horse tight to make it stop and to make it run faster. Your using your legs to climp on and off the horse and they are apart when your actually sitting on thee horse. When the horse trotts, your legs move further backwards and your back moves further fowards. So mainly it's your arms, legs and back.
the horse is very fast
a stanardbred or thoroughbred mix would make a nice fast horse.
Yes you want a horse who can zoom around a barrel. Long legs can make you faster but can not turn or lean as easily. Try out the horse and see if you like it. What is best for you is the best racer!
To make the Barbie Champion Tawny Horse walk, you should first make sure that you have placed the four AA batteries in correctly. Next push the horse's head. This will make her walk. You can also pull her back legs, and press her tail to make her do other things.
I think pull the rope back. A noseband or martingale should not be used to substitue training. You need to train the horse to be collected. Light pressure pulling back while tapping your legs against the horses sides is the cue I use. By pulling back, I look for the horse to bend at the poll, which will make him round up, and by tapping my legs on him, I am saying, keep going. Eventually, you can just tap your legs on his side to get him to collect.
A horse if frightened will bolt (run away), kick, bite, strike out (front legs hit hard onto the enemy) and rear (front legs go up widely and come back down with a loud sound hopefully scaring the enemy away this will also make the horse look hug in size.)
To get make the best offspring based on the parents traits. Example: if a breeder was trying to make a super fast horse, he would make sure that two fast horses breed to make a fast horse.
Horses only have four legs... so if you meant to ask "why do horses have four legs" then the answer would be that four legs fit the horses needs the most, for example six legs would make it hard to turn and would make the horse too long. But in the same way two legs wouldn't be enough because the horse would have to stand on its hind legs and since it wasn't made for two legs the horse wouldn't be able to stand up and would fall over.
the face-where your bridle goes to stop rubbing! the back and tummy-where your saddle and girth go! and in between the armpits-to stop any rubbing when the horse moves its legs!
If you mean legged race...... make your legs long enough. Just right so it can go fast!
Horse riding will certainly tighten the muscles in your bottom and legs.
