Sarah McGregor, a spokesperson for Becky's Hope, explained that the "kill lot" in North Texas where the horse, named Bubbles, comes from is the last place animals get a chance to be rescued before heading to Mexico for slaughter.
"Oftentimes, the horses or donkeys are old, or the owners lost their property, or the owners passed away or simply are unable to care for them and they are sold to auction," McGregor told The Dodo. "If they are not bought at auction by people or other farms, the slaughter pipeline will buy up all of the animals and resell them."
This was very nearly Bubbles's fate - before he decided to adopt his own rescuers. "We stood there staring as this old guy with crumbled ears from frostbite waited patiently for the group of mini donkeys to catch up so he could jump on the 'freedom trailer' out of there," the rescue wrote. "There was just no way we could leave him behind!"
