How do you earn equus on horse other than getting a job

Selling horses, items, etc. and passing riding levels. You can sell 'UFOs' that fly across the screen such as apples. In the store, you can sell horse dung, too, which is fairly profitable. Try entering your horses in competitions once you buy a set of tack and horseshoes, you can win equus and your horse will gain skill. In the forums, there is a topic about earning equus. You should visit it and read about it, even though I said most of it here.
