In comparison, those without a dog to walk will travel less than 14 miles each week.
It also emerged that not only are they fitter, but almost half of dog owners believe having a four-legged friend has improved their overall mental health and reduced stress levels.
The study found the average pooch is taken on a walk an average of nine times a week, for 34 minutes on each occasion.
With each walk covering almost two miles, that means a total of around five hours a week - or 11 days a year - is spent exercising the dog.
More than a third of dog owners also said they walk further now than they did before getting their four-legged friend.
And three quarters of non-dog owning adults wish they did more walking, with 46 per cent believing they would go out more if they had a pet to exercise.
It also found 23 per cent of dog owners believe their pet has made them more sociable while 16 per cent feel more connected to the community, with the average owner striking up two conversations with fellow dog lovers during each walk.
Dog walking isn't always perfect though, as before pet owners even step outside the door, there will be more than 100 family rows a year over whose turn it is to take the dog for a walk.
More than a third of dog owners also admit they try and pass the walk on to their children – an average of four times a month.
A quarter don’t have time to walk their dog any more than they already do, while one in five are too busy with work issues.
During the walk, dog owners also use 936 poo bags, play 2,340 games of fetch and call their pet’s name at least 1,404 times annually.
Gemma Cunningham, spokesperson for Lintbells, which commissioned the research said: “Dogs can be a great addition to the family and a real incentive to get out and spend some quality time with your family and friends.
"It’s great to see that the results of the survey show how much our dogs have a positive impact on owners' lives.
"It is important to take time out of your busy schedule to exercise – both for your own and your canine’s overall health and well-being.
“Just like humans, dogs are social beings and don’t welcome loneliness, so getting out and exercising can be a perfect way to leading happier and healthier lives.”
