I know where you are coming from, but I would have to put my dear pet down. We are retired and couldn’t afford to do it. I have had to put down a 19 yr old poodle. It was selfish of me to have kept her going. Everyone and every animal is different, but you shouldn’t feel guilty if the animal is put down.
I agree with you ...no one should feel guilty about putting an animal down. Most true animal lovers do whatever they can in a compassionate way and we need to honor their decisions.
