The bond between man and dog is so strong that their hearts beat in sync, a study has found.

Australian researchers separated three dogs from their owners, strapped heart monitors on the people and animals and then watched what happened when they were reunited.

Doggy and human heart rates quickly fell – and then began to mirror each other.

Charts showed that despite beating at different rates, they followed the same pattern, with each dog’s heart rising and falling in tandem with its master’s.

Researcher Mia Cobb, of Melbourne’s Monash University, told the Huffington Post: ‘I was impressed at how much they came together.

‘The fact that they shared patterns do closely surprised me.

‘This kind of effect of experiencing a lowered heart rate makes a significant difference to our overall wellbeing.

‘If we can decrease our heart rate by hanging out with our animals, that’s something that can really benefit the community.’

Colleague Dr Craig Duncan, said: ‘Stress is a major killer in today’s society and, as we get busier and busier, it is something that is really important for us to try to help with.

‘The Hearts Aligned project aims to show how pet ownership can help us positively deal with the stressors of everyday life.’

The study, which was funded by pet food firm Pedigree, is just the latest to show that having a dog is good for the heart.

For instance, a review of research by the American Heart Association suggested that pet owners have healthier hearts than other people – and dog owners particularly benefit.

This may be because of the necessity to go for walks, whatever the weather.
