Pet ownership, loneliness, and social isolation: a systematic review

This systematic review examined 24 studies to evaluate whether pet ownership affects loneliness and social isolation. Results showed mixed evidence; while some studies indicated that pet ownership, especially dogs, might reduce loneliness or isolation, others found no significant effects. The COVID-19 pandemic appeared to amplify pets' positive social impact, as they provided companionship during isolation. However, benefits varied widely based on individual factors, pet types, and study designs. This underscores the complex relationship between pets and social well-being.

If experiencing loneliness, consider owning a pet, particularly a dog, to potentially improve social-engagement and reduce feelings of isolation. However, as the evidence is mixed and derived from observational studies, pets should complement—not replace—human social connections. Evaluate your capacity for pet care responsibly.
