Nick,
Jeez, thats **** news. i have had four dogs in my lifetime, and loved them dearly, they are mans best friend for sure. One thing i find is ever time i think of them, i am happy, as they bring back intense and very happy memories, that will be with you and your wife for many years. I hope your pain gets easier with time, and if you decide to keep a pup, it will fill your hearts with joy.
Tony
