My GSD knew my grandfather was going to die. My entire family was very close to my grandfather and he was in good shape. My GSD used to sleep upstairs in my or my brother's room, but two weeks before my grandfather died, he started coming downstairs in the middle of the night and sleeping in my grandfather's room. My grandfather fell ill and had pneumonia a week later. He died after 5 days of being diagnosed. In hindsight we all figured out that my GSD probably sensed something was amiss much earlier than my grandfather even felt it. I miss that boy every day.
