My dad had a dog he trained and trained to herd cows but was only good at attacking them and spreading them out. He was dispatched with the same rifle we used to shoot coyotes. Left him where he fell. Within a few days there wasn’t anything left but a collar.
I get that. I don’t know if I would make that same decision in the same way, but to many working farms or ranches, an animal needs to have a purpose if it isn’t fully a pet in the standard sense, and I cannot put myself in their shoes.
So, I won’t judge them.
