The breastfeeding by humans of animals is a practice that is widely attested historically and continues to be practiced today by some cultures. The reasons for the practice are varied: to feed young animals, to drain a woman’s breasts, to promote lactation, to develop good nipples, to prevent conception and so on. One example of the practice being used for health reasons comes from late 18th century England. When the writer Mary Wollstonecroft was dying of puerperal fever in 1797 following the birth of her second daughter, the doctor ordered that puppies be applied to her breasts to draw off the milk, possibly with the intention of helping her womb to contract to expel the infected placenta that was slowly poisoning her. Similarly, English and German physicians between the 16th and 18th centuries recommended using puppies to “draw” the mother’s breasts, and in 1799 the German Friedrich Benjamin Osiander reported that in Göttingen women suckled young dogs to dislodge nodules from their breasts.

In the study, subjects who were under stress showed significantly more positive social behavior than control subjects who were not in a stressful situation. Negative social behavior, on the other hand, was not affected by stress.
