There is no denying the fact that a pet, be it a cat or a dog, always has a positive effect on people. Now it has been proved by science!
According to a recent research, dogs change their facial expressions in response to human attention. Another research proves that cats crave for contact with their owners when they come back after a long absence.

It’s difficult to resist a pair of puppy eyes or those mournful expressions of your favourite Pug or a Labrador, isn’t it? No wonder, we tend to change our behaviour in response to their expression.

Now, don’t be surprised if we tell you that dogs can change their expressions intentionally when humans are around! To prove this, a group of scientists at the University of Portsmouth in England conducted a research on 24 pet dogs. Each dog was then taken to a room and tied by a leash. A researcher then stood three feet away from the dog in three different positions—facing the dog with a handful of food and without food; facing away from the dog with food and without food.

Interestingly, they found that when the researcher was facing the dog, it produced twice as many facial expressions when the researcher was facing away from it. And ‘puppy dog eyes’ was the most common expression.
