Preliminary study of the impact of different dog features on humans in public

Revealing why pedestrians are afraid of some dogs while passing them in public is essential to assess the dog–owner–stranger relationship. Therefore, the effect of different dog features on passersby was gathered. Four dog features differing in size and color were investigated. The dog features were classified as small-dark, small-pale, large-dark, and large-pale. Dog's effect on passersby was recorded in 2 ways: (1) observing the behavioral responses of passersby while passing nearby a dog, and (2) revealing the passersby's perception of that dog by a short interview. Direct observations of 427 passersby's behavioral responses while passing a dog on a sideway were acquired, and 126 persons were interviewed. It was suggested that large-dark dogs seemed to be more threatening than pale or small dogs. Passersby confronted with pale dogs of equal size changed their way far less than when confronted with dark dogs. Significant differences were noted for the type of effect assessed and the reason for this behavioral response. The results showed that only the small-pale dog appeared to be friendly because of its size (P = 0.000). All other dogs were stated as friendly because of individual factors including breed and own dog experiences (P = 0.000). None of the dogs were mentioned as threatening. Our results show that some dog features have a significant effect on behavioral responses and the subjective perception of dogs by people in public.
