Bro BlueC, I am kinda going through this now as well..
my boy had been with me for 9 years... but health is going down since last year...
for the last 2 week, his hind legs are unable to work.. pass motion and pee is a problem for all..
as I told my wife.. he cant tell me what he wants.. and I do not have the heart to make the decision for him as well..
