I can only think of GSD owners that are dead now. o.0
Bing Crosby, Yvonne deCarlo, Phyllis Diller, Irene Dunne, Joan Fontaine, Eva and Zsa Zsa Gabor, Bob Hope, Jackie O and JFK, Roosevelt, Reagan, Picasso. . .Hitler.
David Letterman had one but I don't think it's still alive. Same with Joan Rivers.
If anyone has some info on dogs and owners that are still alive, that would be helpful.
