I own a 24 year old horse I’ve had for 2 decades. He looks shiny as a penny. He eats well. And he has a hard time breathing. I treat him daily and he’s occasionally fine. At some point, possibly this very summer, I may put him down. It is going to be 98F next Friday. And likely 90% humidity. I seriously doubt I can get him comfortable. I will bring them to my shadiest lots and turn on the big fan in their run in…but I predict a very hard summer for him.
Why would I keep him alive to spare myself the reality of his QOL? Why would I even consider entrusting him with a stranger in some magical other place where he’ll miraculously be fine?
He is mine and I will steward his care as I see fit. Your judgement of the OP is just this side of delusion about what’s out there, what’s possible, and what’s just.
