We now know that in addition to the long recognised companionship, caring, sharing and security aspects, pet ownership can have a very positive health effect. The following discussion highlights only some of the studies that have been conducted relying where possible on the most recent Australian work. The health benefits of pet ownership are increasingly being recognised. There is something soothing about stroking and petting an animal. They are uncomplaining, unvengeful and unjudging in their relationship with their owner and are now suggested as a drug free way of coping with stress.
Dogs also encourage owners to exercise.
Proof of the therapeutic benefit of pets becomes stronger every day as more studies and case histories become available. The seminal work by Dr. Warwick Anderson of the Baker Medical Institute in Melbourne showed that pet owners had significantly lower risk factors for cardiovascular disease than non-owners. Some 5,741 people participated in the study that revealed a beneficial effect of pet ownership on several of the classical factors for coronary heart disease. Dog owners in the McHarg et al. survey also reported better physical and mental health than non dog-owners. They go to the doctor less often.
