Oh, I agree that this foal had/has no future, but I can also see how hard it is to stop and I don’t believe the people in charge of his care are evil and intentionally cruel.
I had a dog with chronic orthopedic issues that developed horrible GI issues. I called a halt when they wanted to ultrasound his stomach to see if he had stomach cancer. The only treatment would be to remove part of his stomach. His vet is a wonderful caring man and a great vet, but sometimes they get wrapped up on the “I can fix this” and don’t stop to think on if they should fix it.
