I am truly sorry for your loss, my German Shepherd passed away on Saturday also, the worst part was I was not there to say goodbye, I was told she waited by my car, they say to say goodbye, but I feel it was for help.. Besides some arthritis that was being treated, she was in great health as far as I know.. I think I could have helped but more so I wish I had the opportunity to say goodbye and feel her beautiful coat against my skin one last time. If not that I wish I could have buried her myself, it was something I promised to do along time ago. They say mans best friend, even though they only live a quarter of our lifespan.
I am happy that you had the chance to say goodbye and I hope that they crossed the bridge together, they look like they would have been pretty good friends.
