Howrse has had a bit of a change around and you can no longer put comments/messages when selling your howrse. Only if you put your comment for the horses name!.....
You cannot. Only Howrse themselves can put items up for sale in exchange for sand.
No Just The Horse That You Put A Philosopher's Stone On
Go to the auction page and click on the button just above the horses for sale that says "display only my sales" then it will give you a list of the horses that you put up for sale click the magnifieing glass just to the right of the comment (if you wrote one) then up the top of your horses sale there will be two buttons and one of them says "cancel the sale" click on that, then you will have to pay a percentage of the price.
Just put your horses to bed. The next day, do that again.
Companions were sold on Howrse for a limited time, sort of like the Lottery; its a short phase. Only now can you buy rare horses with companions instead of buying companions to put on horses. Hopefully Howrse will bring them back
Yes (its a question from howrse)
That's easy. Just hover over the 'Community' tab and then click 'My Friends.' There will be little icons to the right of each of your friends names. When you see the friend you want to put a comment, click the icon beside it that says 'Modify The Friendship' when you hover over it and put your comment in the box that pops up. ;) Hope I helped!

sell horses , bm items, sell items in your stock , stroke horses in the haven , put horses in the haven , do comps , do lessons .
you put horses to bed 12 times it does not have to be 1 horse(aging counts too)
It is impossible unless you put the companion on a horse and trade horses. Hope this helps :) -Chelsea111
When you have enough karma points (you need two) you can reserve an affix.
Many players have lists of symbols in their forums which you can copy a heart from, and paste it into your horse's name when editing.
