For example, Kelpies and Boxers both displayed intermediate levels of fearfulness during startle tests; however, Boxers responded by becoming inhibited, whereas Kelpies responded with high activity (Goddard and Beilharz, 1985a). Breeds reported as showing low fearfulness toward startle stimuli have bee...
