On the subject of odor, human odor including mouth odor is very offensive to them, we smell like predators.
Who trained a deer to pick out the smell of a humans mouth/body odor as being a predator? Has a "normal" human ever physically attacked a deer as a predator would? Do deer feel the breath odor of a squirrell, rabbit, hog, beaver, ect., is threatening to them. All animals have breath odors. How do deer decipher which ones are a legitimate threat to them?
