How do you get rid of a golden apple on Howrse?

You can trade it with others for something else that you fancy, to do this you go the the store and click the button saying 'exchange items' it easy to use and get some great deals.

you can give it to a friend, bit too generous though!

if you mean a golden Apple that is already placed on your horse, it is impossible to take off.

You could advitise it on your howrse page, and maybe someone will be intrested in buying it for so many equus.

Hope this helped:)
