re: Old dog. At what point you say good bye?

True story here...my grandfather had a bird dog that was awesome to me from the time I started quail hunting with Pappaw. He got on up in age and my Pappaw took me with him quail hunting with 'Buck'. Buck got to where he wouldn't retrieve and even made perfect points except he was pointing rats. Pappaw called him back, removed his collar, and sent him back out. Seconds later, my Pappaw shot him. Cried my eyes out that day.
