EVEN UNTRAINED DOGS RESPOND

TO HUMAN COMMANDS

Here’s proof even stray dogs are good boys: 80

per cent of untrained stray dogs can still

understand human cues, Indian researchers have

found. Studying stray dogs across several Indian

cities, Dr Anindita Bhadra of research institute

IISER Kolkata and colleagues found the animals

successfully followed pointing directions – either

momentarily or repeated – when presented with

two covered bowls of food. Stray dogs are a

common feature in cities around the world,

particularly in developing countries, and this

research could be key to understanding how

humans shape stray dog behaviour. However,

researchers did note that shyer, more anxious

animals tended not to participate, so more work

is needed to determine a potential link between

the ability to understand human cues and

personality traits of the dogs.
