1. Go to your horse's profile: Click on your horse's name from your stable or from your horses list.
2. Click on the "Stable" tab: This tab is located at the top of your horse's profile page.
3. Choose a stable: You can choose from your own stables (if you own any) or search for available stables in the "Stable" section.
4. Send your horse: Select the stable you want to send your horse to and click on the "Send" button.
Important things to remember:
* Stables have fees: Using a stable will require you to pay a daily fee, which is deducted from your account balance.
* You can only send a horse to a stable that you own or that has space available.
* You can choose to send your horse for training or just for safekeeping.
By "boxing" your horse in a stable, you are essentially sending it to a safe place where it can be trained, recover from injuries, or just rest.
