This wasn’t all Maria had gone through. Keith believes she’d also been used in some kind of glaucoma study, and whatever experiments the researchers did to her had left her blind and traumatized.
“Several of the dogs from that facility were blind, or they had horrible glaucoma and we had to remove their eyes because they were in so much pain,” Keith said. “That’s not a coincidence — it’s obvious that it’s something they did for them.”
The lab eventually decided it no longer wanted Maria. “Usually, facilities will agree to release dogs when they’re ‘spent,’ meaning they’re no longer useful to them,” Keith said. “At this point, Maria was old, she was fragile and blind.”
