To investigate, Anindita Bhadra and colleagues have studied stray dogs in various cities of india: researchers have come closer to the exemplary solitary and have placed two bowls blankets on the ground near them. A researcher has then indicated one of the two bowls, one time or repeatedly, and has recorded if the dog approached the bowl indicated. It was also described the emotional state of the dogs perceived during the experiment. About half of the dogs have not approached to any bowl.
However, the researchers noted in these dogs, an attitude of anxiety in the past may have had bad experiences with humans. The dogs who came to the bowls appeared to be more friendly and less anxious, and about 80% followed correctly the signals 'pointing' towards one of the bowls, regardless of whether the indication was a momentary or repeated. This suggests that dogs may actually be able to decipher the gestures of the complex by the man. "It is quite surprising that dogs follow an abstract gesture such as a finger, which indicates an object for a few moments," explains Bhadra. "This means that they saw the human being is met for the first time, and used their human understanding to make a decision. This demonstrates their intelligence and adaptability".
