Free-ranging dogs quickly learn to recognize a rewarding person
Individual human recognition is important for species that live in close
proximity to humans. Numerous studies on domesticated species and urban-adapted
birds have highlighted this ability. One such species which is heavily reliant
on humans is the free-ranging dog. Very little knowledge exists on the amount
of time taken by free-ranging dogs to learn and remember individual humans. Due
to their territorial nature, they have a high probability of encountering the
same people multiple times on the streets. Being able to distinguish individual
humans might be helpful in making decisions regarding people from whom to beg
for food or social reward. We investigated if free-ranging dogs are capable of
identifying the person rewarding them and the amount of time required for them
to learn it. We conducted field trials on randomly selected adult free-ranging
dogs in West Bengal, India. On Day 1, a choice test was conducted. The
experimenter chosen did not provide reward while the other experimenter
provided a piece of boiled chicken followed by petting. The person giving
reward on Day 1 served as the correct choice on four subsequent days of
training. Day 6 was the test day when none of the experimenters had a reward.
We analyzed the choice made by the dogs, the time taken to approach during the
choice tests, and the socialization index, which was calculated based on the
intensity of affiliative behaviour shown towards the experimenters. The dogs
made correct choices at a significantly higher rate on the fifth and sixth
days, as compared to Day 2, suggesting learning. This is the first study aiming
to understand the time taken for individual human recognition in free-ranging
dogs and can serve as the scaffold for future studies to understand the
dog-human relationship in open environments, like urban ecosystems.
