Some of these reasons include health benefits and psychological benefits.
Pets help in the reduction of stress by improving the pet owner's psychological well being.
Since dogs require regular walks, the owner is more active. Health problems, such as blood pressure and cardiovascular problems are reduced in people who have pets. The family pet also affects the psychology of children. Emotional attachments often develop due to the companionship and protection from these animals. These attachments help pet owners deal with loneliness and depression.
