Why not just take him to the vet and do it the right way
well see our thinking is how would we want to go? to be taken to a strange place where you (if you’re animal especially) you can smell the sickness / death that comes with a vet clinic.
you’re around people you don’t know ….
personally …. I want to die at home in comfortable surrroundings and trust me .. a shotgun blast to the back of the head is ever as quick if not quicker than getting held down on a steel table, feeling the shot go into you ….
the thing is … its all perspective. Personally I would choose dying at home and on top of that ….. the animal has no idea its coming
one last thing another friend brought up … they still shoot horses that get broken legs don’t they? *I have no idea.
