It has been well-documented that just going outdoors has both physical and emotional benefits, as does any form of exercise. Research has also shown that having a dog makes it more likely that people will combine the two, usually by walking, which also has several positive effects, including reducing pain. Spending time with a pet also counteracts stress, which improves health. A final advantage to walking a dog is that unlike other forms of exercise, it does not cost anything.
