Stray dogs have ability to understand human gestures

Researchers have found that untrained stray dogs have the natural ability to understand human gestures and respond to some cues better than the others.

A study revealed that 80 per cent of participating dogs successfully followed pointing gestures to a specific location despite having never received prior training. The results suggest that dogs can understand complex gestures by simply watching humans and this could have implications in reducing conflict between stray dogs and humans.

"This means that they closely observe the human, whom they are meeting for the first time, and they use their understanding of humans to make a decision. This shows their intelligence and adaptability," Bhadra added.

Dogs were domesticated 10,000-15,000 years ago, likely making them the oldest domesticated animals on the planet. Humans then bred dogs with the most desirable and useful traits so that they could function as companions and workers, leading to domesticated dogs that are highly receptive to human commands and gestures.

However, it was not clear whether dogs understand us through training alone, or whether this was innate.

To investigate, the research team studied stray dogs across several Indian cities. Researchers approached solitary stray dogs and placed two covered bowls near them.

A researcher then pointed to one of the two bowls, either momentarily or repeatedly, and recorded whether the dog approached the indicated bowl. They also recorded the perceived emotional state of the dogs during the experiment. Approximately half of the dogs did not approach either bowl.

However, researchers noticed, these dogs were anxious and may have had bad experiences with humans.

The dogs who approached the bowls were noted as friendlier and less anxious, and approximately 80 per cent correctly followed the pointing signals to one of the bowls. This suggests that the dogs could indeed decipher complex gestures.

The results suggest that dogs may have an innate ability to understand certain human gestures which transcends training.

"We need to understand that dogs are intelligent animals that can co-exist with us. They are quite capable of understanding our body language and we need to give them their space. A little empathy and respect for another species can reduce a lot of conflict," Bhadra said.
