Stan, thats an amazing story about the bulldog. Apparently it happens more often than we realize. A few years ago, there was the video of the Navy Seals dog which laid down by his masters casket during his funeral service. In Japan, school children are taught the story of Hachiko, an Akita, that after his masters death in the 1920s, went to the train station every day at the time his master would normally arrive from work. He did this for 9 years until his death.

I found a collection of essays and sayings about losing dogs and grief and one of the most poignant was attributed to Napoleon:
This soldier, I realized, must have had friends at home and in his regiment; yet he lay there deserted by all except his dog. I looked on, unmoved, at battles which decided the future of nations. Tearless, I had given orders which brought death to thousands. Yet here I was stirred, profoundly stirred, stirred to tears. And by what? By the grief of one dog .'
Napoleon Bonaparte, on finding a dog beside the body of his dead master, licking his face and howling, on a moonlit field after a battle. Napoleon was haunted by this scene until his own death.
