I just found out today that this person has done this before. Boarded
her horse somewhere for months to a year without paying and then at night
secretely "stole" her horse. But, I live on my horse property, and
my 110 pound male German Shepherd is out on guard duty at night, so she might
sneak in, but she won't sneak out without the dog alerting me (and possibly
alerting her ass) and my security lights flashing. I am putting a
lock on the stall and pasture gate. Thanks for the
tip.
