Dogs are the secret to a happier and less stressful life. And that’s not just an opinion by dog lovers, that’s a scientific fact. Research shows that dogs not only makes us happier, they also make us healthier.

One study found that dog owners had higher self-esteem and dealt with social rejection better.
