Between psychic suffering and care: the role of animals in depression

Depression and Generalized Anxiety Disorder (GAD) are among the most pressing challenges in contemporary mental health, affecting millions of people across different social and academic contexts. Although conventional treatments, such as psychotherapy and medication, are essential, they do not always provide immediate and continuous relief, leading to the search for complementary strategies of care. In this context, animals emerge as indispensable allies, offering presence, companionship, and comfort that extend beyond traditional clinical interventions. This article presents a narrative review of the scientific literature, complemented by the author’s lived experience with depression, panic attacks, and GAD, highlighting how companion animals and non‑conventional species (such as reptiles, birds, fish, and small mammals) contribute to stress reduction, emotional regulation, and adherence to therapeutic care. Findings emphasize that animals do not replace conventional treatments but complement them in unique ways, promoting resilience, well‑being, and strengthening the human–animal bond as a resource for mental health support.
