Unfortunately, players are capable of feeding other players' horses, unless, they are in the sales. If they are selling in DIRECT SALES, you can feed them an apple.
If the horse is a Divine or Special, Howrse allows you to feed and pet them and in return you can either win 1000 Equus, a Horn of Plenty or some apples.

Feed your horse every day or your horse will die.
You feed your horse by clicking the feed link to the top left of his page and selecting the amount of forage and grains to give.
To raise your horse's energy on Howrse, you can feed him treats such as a turnip or carrot, stroke him, feed, and let him spend time in the pasture or box.
When you click the button to feed your howrse, it will indicate how much fodder it needs.
Horses are fed hay and oats as a stable diet.
You can only give apples to other people's horses.
You don't feed it to them. You go on the black market, click the golden apple, select the howrse, then the coat, then "confirm". Hope this helps! -Kатнячп•Fυııэя
You feed the horse the most allowed amount, in hope to get it back to it's original weight. You will have to check back everyday, or over feed the horse if you won't be on every day
You have probably already done so.
Go to the feed button on the horses page and it will say it.
When a horse is under weight you should feed him the full amount of forage/fodder that is Possible then age them with an aging point and feed them the full amount! happy howrsing!
