Sorry to hear but you can chalk this one up as a 100% victory as a dog owner and good man. We have to remember that most dogs in the world are not as lucky as this one to live w you and your family. I feel so lucky to know you, I even got to meet this dog!
I was going to write this in Higgin's thread but did not have time. When my white GSD, "Monster", died in 2000, I was a wreck. I mean I could not go out in public for a few days w/o dark glasses, never knew when the sadness would just come over me like a wave of grief.
I finally had to go back to work on some film production job. I remember I was dealing w some Teamster transportation guy when I felt it coming on like when you're about to vomit and there is absolutely nothing you can do to stop it. A little context for non-Hollywood people; the crew guys who handle transportation, stunt people and certain other jobs are not your stereotypical Hollywood liberals. More like they came from Wyoming--drive dually PU trucks, wear cowboy hats, live out in horse country and maybe attend the rodeo.
Anyhow...I had to tell this guy out of the blue that I was falling apart and apologized but my dog just died and I'm losing it. To my surprise, (but I shouldn't have been), he threw an arm around me and said, "that's alright, man. I understand. Dogs are better than people. People deserve to die, often, but not dogs."
