People experiencing homelessness, victims of domestic violence and economically vulnerable people are at higher risk of social exclusion. For them, pets are an important source of emotional support. A study by the Affinity Foundation Chair for Animals and Health of the Universitat Autònoma de Barcelona (UAB) and the FAADA Foundation, published in the Frontiers in Psychology journal, highlights the importance of this support from a multidimensional perspective, drawing on the experiences of 100 individuals in vulnerable situations.
