I bought the stable for my falkreath home but I have no idea how to stable my horse can anyone help?

Well I bought a horse from my steward and the horse just popped in there, my guess would be, go into your house and then out? And it automatically waits there?

The ability to stable already owned horses is not in the game. Doubt this DLC introduced it. Horses are stalkers. When you ride one you own, it never leaves you alone.

Ah, I was hoping to stable shadowmere not some random horse that is disappointing. Thanks for the info!

I would wait on us figuring out more about the dlc before you count this ability out. Like I said, the start out stabled and are rideable, so there MUST be a way to return it to the stable.
