Attention is considered the most basic form of behavior and “both classical and instrumental elements closely cooperate” mediating effective “perception and action” (Lindsay, 2000). In a broader view, “attentional activities specify a dog’s intentions, reveal a dog’s motivational state” and sometimes define what he is prepared to learn, thus “attentional activities” are said to “reflect a dog’s overall disposition to learn” (Lindsay, 2000). How we stimulate and control dog’s attentional behavior can have profound effect on training and behavior modification. Lindsay (2000) says “dogs pay attention to occurrences that are significant to them and learn to ignore occurrences that are irrelevant” and stimuli associated with pleasurable events or those associated with fearful events gain the most attention than other irrelevant stimuli.
