A person dies and releases death scent as body immediately starts decomposing. This stains the surface, ground, and surrounding area with the scent. The dog smells this, becomes physically upset, starts eating grass to settle stomach build up of acid in stomach, ears down, tail down, whining, urinating, pooping, may or may not bark. The dog is VERY SAD. (See Dela Carlson, Tommy Gibson, Lynn Topp, Claudia Kirschoch search reports).
