When celebrating the dog wagging its tail to the right

This four-legged friend wagged his tail to the right or left, depending on how he felt, Italian researchers revealed. The dog will turn its tail to the right when happy or see something eager to see. On the contrary, the tail swings to the left if it is threatened and faces what makes it want to stay away.

Professor Giorgio Vallortigara from the University of Trieste and his colleagues described this "asymmetry in controlling tail movement" and other examples of how the right and left brains control different emotions.

The researchers examined 30 pet dogs, including 15 males and 15 females between the ages of 1 and 6. They placed these animals in a large, rectangular black wooden box so they could not see the side. out.

Vallortigara and his colleagues filmed the dogs' response when exposed to four different stimuli: the owner, a stranger, an unknown big dog and a cat. "When exposed to owners, dogs tend to wave their tails to the right," the researchers found.

The tail remains in this direction when they see a stranger or a cat, although with strangers the frequency is less waved and the cat is fluttering at least. But in front of a strange and tall male dog, although also placed in the barn, the tail of the experimental dogs tilted completely to the left.

However, this study does not mean that you can freely appear in front of a dog without guarding its bite.
