Jimbob, excellent point! You just touched a nerve. My dear old friend, Bridger the lab, had reached the end and couldn't get out of bed a few years back. I took him to the vet and they did their work.
I have never been able to forgive myself for not taking him to the ranch and letting him be in his favorite spot while "I did my duty". Live and learn.
I will use the .22 mag next time! Sorry for the loss of your dog JD.
