Nick the Neurotic Dog

Gantt's subjects included Fritz the Alsatian, Peter the beagle, a male poodle known as "V3," and especially the mongrel Nick, subject of "the most meticulous and complete case history of a single animal to be found in the conditioned reflex literature." These animals and others like them were subjected to a barrage of procedures to study conflicts of the drives between, for example, experimentally induced anxiety states and sexual excitement... Nick, in particular, exhibited symptomatic erections and ejaculations whenever he encountered stimuli associated with previous situations of anxiety. Years after one such experiment, in which anxious reactions were elicited by requiring dogs to make a difficult distinction between two tones of similar pitch (a distinction that determined whether the dog was fed), Nick would develop a "prominent erection... within a few seconds after the onset of the tone," Gantt enthused. "We could always count of Nick for a demonstration."
