A Study has found in the British Psychological Society that Dog owners are healthier than other pet owners or don’t have.
Deborah wells, a lecturer at the Canine Behavior Center of Queens University in Belfast, studied and found there is less chance of diseases in dog owner rather than other pet or don’t.
According to Wells, “It is possible that dogs can directly promote our well being by buffering us from stress.”
As stress is the main cause of several diseases such as auto-immune diseases, heart disease, blood pressure etc. But dog ownership reduces all risk factors related to stress.
