Taking all noncognitive tests into account, young and aged dogs exhibit distinct behavioral profiles. Young dogs exhibit higher levels of activity and more interest in interacting with toys, people, and artificial dogs, which modifies their movement pattern as shown in Figure 35.5. Aged dogs show decreases in locomotion and other behaviors but continue to display appropriate responses, just to a lesser extent than young dogs. Impaired dogs by contrast show abnormal responses. These dogs are hyperactive, unresponsive to social stimuli or toys, and often engage in stereotypical behaviors. These impaired subjects display atypical social responses on tests of human and mirror-image interactions. The profile of the impaired dogs is consistent with behavioral disruptions that occur in demented people.
