There are two ways to manually modify a current Horse's Location and/or Status.

Beneath the Horse Name on a horse's profile, click the Edit pencil.

Then modify the Location and/or Status (and optionally the Barn/Paddock and Box). Be sure to set the date that the change was effective.

On the Horse Profile, scroll down to the Location History section. Then click Add.

Enter the Location and Status (and optionally the Barn/Paddock and Box). Be sure to set the dates that the change was effective From and To.

You can use this function to add a new Location/Status history or add a new historical record where data was missing or needs correcting.
