Petting dogs makes people more sociable.
New findings have revealed that watching, feeling and touching pooches boosts neurons in the area of the brain that regulates emotional interactions in a way that petting a cuddly toy couldn't.
It is hoped that the research conducted at the University of Basel in Switzerland can improve treatments in animal-assisted clinical therapy for human beings.
Researcher Rahel Marti said: "They are clinically relevant for patients with defects in motivation, attention and socio-emotional functioning.
"Integrating animals into therapeutic interventions might therefore be a promising approach for improving emotional involvement and attention."
Meanwhile, another study has shown that pets were a huge benefit for people's mental health during the coronavirus pandemic.
A survey conducted by the University of York found that almost 90 per cent of owners said that their animals had helped them cope better emotionally during the lockdown.
