Like any enjoyable activity, playing with a dog can elevate levels of serotonin and dopamine -- nerve transmitters that are known to have pleasurable and calming properties, he tells WebMD.
"People take drugs like heroin and cocaine to raise serotonin and dopamine, but the healthy way to do it is to pet your dog, or hug your spouse, watch sunsets, or get around something beautiful in nature," says Justice, who recently hiked the Colorado Rockies with his wife and two dogs.
Good for the Heart
Heart attack patients who have pets survive longer than those without, according to several studies. Male pet owners have less sign of heart disease -- lower triglyceride and cholesterol levels -- than non-owners, researchers say.
