As the title says, really.

Is there any way to call your horse to you? So often I lose him and don't see him again until I fast travel somewhere else.

Many thanks.

Nope just fast travel to the closest spot to you.

this isnt red dead redemption!

that would be nice tho, horses spaz during combat sometimes and cant even find them afterwords lol

Fast Travel is the only way to call a wayward horse to you. Also, when you travel to a city that has a Stable, that is where the horse ends up.
