not if ride for a long time
yes but not for to long. and when you say heat, i hope you mean like hot weather by your question. ****************************** lol to who ever wrote that^^ but if your mare is in heat you should not ride her! It could be dangerous, specially around stallions and some geldings. When my mare went into heat she went all weird xD haha
I have heard 6 months
All you have to do is ride your horse long enough and you'll gain a star. You will need to ride your horse for many hours to get it to ten stars.
it takes aproximatly 2min and 45sec if the horse has steroids.
Long distance
Kinetic energy is used when you ride a Horse
you ride a minichre horse like someone would ride any other horse
2 years is best but if you would like to ride it younger 8 month won't hurt . but for the first mount you have to ride the horse for about 3-5 muinites leats on you can ride it for longer , and longer and so on.
You can really ride a horse how much you want depends on the horse is it fit? is it over weight and needs excersising? you could ride it every day if you really wanted to but not for a very long time.
So long as there are no serious problems with the horse you can ride it. Many horses are ridden well into their teens and even twenties with no ill effects.
That is unknown, since it was a long time ago.
