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. Fewer take medication for high blood pressure, sleeping difficulties, high cholesterol or a heart problem. A former guide dog named 'Honey' was introduced into two long-term care wards which accommodated 60 frail and elderly patients.
Pets also help to foster family cohesion.
McCallum Research Pty Ltd et al. considered this question in light of the greater complexity of family relationships arising from divorce, the blending of families, the pressures on working mothers or conversely of unemployment. Pets can act as emotional substitutes for spouses, romantic partners and children. They found that the people who felt closer to their pets tended to be those without a present spouse or romantic partner, who have no children or have no children present in the home. They found that widows, single people and empty nesters are more likely to emphasise the companionship qualities of pets.
