Pictures of the two 8-week-old foals show the heartbreaking condition they were found in -- dehydrated, and starving.
Everyone was angry about it.
The two were rehabilitated, and now Lightening and Cactus Cowboy are on the road to recovery at Care the Horses program in Sierra Vista, in Southern Arizona.
No one is sure how the foals got into this condition, but horse abandonment is certainly a problem according to Ann Jost.
"However, we've had it happen with thoroughbreds, quarter horses, so it's not uncommon for people to leave their home, and have no resolve or any other way to get rid of their animals. And they dump them in the desert and expect them to survive," said Jost, who runs Care for Horse Rescue with volunteers and donations.
In the valley, the people who run Tierra Madre Horse Sanctuary are caring for 33 horses who have been abandoned or turned in by their owners.
"Or we have horror stories where they have a broken leg, and they're going to be shot, or this pregnant mare that we had who was going to be sent to slaughter, and her foal aborted. So it's disgusting, and it's sick," said Alexis Roeckner.
The foal is now eight months old and is with it's mother at Tierra Madre Sanctuary.
The other two foals are on the road to recovery in Sierra Vista.
Both rescues say they worry about the horses they don't get to.
