In this chapter from a forthcoming book, The Dog—A Psychobiologic Study, the emotional life and personality of man's truest and oldest pet is illustrated by anecdotal material picked from the literature.

Like human beings, dogs may be depressed, elated or envious and display shame and guilt feelings, dependent on the moral standards established by their masters. Suicides occur as a result of loss of a love object. The common dislike for strangers is explained by the animal's fear of rivalry with regard to his master's affection. Such observations call for a more exhaustive, psychodynamic study of individual neuroses; the more so as we learn that the canis domesticus dreams, lies, malingers, murders for love and occasionally enjoys an alcoholic inebriation.
