Yeah, I was is the 'room' only once during the 'put down' of one of our animals.
His name was Nugget and he was a golden retriever. He had pretty bad cancer and all of his organs were going. It was really sad because I was only seven and he was seven when he got put down. I agree with Trapper in the sense that you should be in the room when they're being put down, because really at that time all they need is you
