Swiss study challenges link between pet ownership and improved health

A new study conducted in Switzerland, involving researchers from the University of Basel, the Swiss Tropical and Public Health Institute, the University of Lucerne, and the Open University in the Netherlands, challenges the common belief that owning a pet automatically improves health or happiness.

Analyzing data from over 2,300 Swiss residents, the research found no measurable general benefit to physical health or psychological well-being simply from owning an animal. Interestingly, pet owners reported slightly worse health states on average and higher daily cigarette consumption. The study noted no significant differences in loneliness, life satisfaction, or medical visits between pet owners and non-owners.

Researchers suggest a “selection effect” may be at play, where individuals already experiencing stress, loneliness, or health issues are more likely to adopt pets for comfort. The study concludes that benefits depend heavily on the specific relationship; those who invest more time in their pets perceive stronger emotional support, with dogs being associated with the highest levels of emotional support.
