In Portugal, the relinquishment of dogs and cats is a major problem. Thus, the authors developed a questionnaire to understand the factors influencing the relinquishment of companion animals in Portugal. With a view to analyze the factors behind relinquishment by companion animal guardians, the authors analyzed surveys completed by 72 participants, divided into two groups: REL (relinquisher, n = 36), i.e., guardians who had relinquished a companion animal and NREL (non-relinquisher, n = 36) i.e., guardians who had never relinquished a companion animal. The only significant factors for the REL group were the presence of children and the type of dwelling (apartment). Additionally, the duration of guardianship of the companion animal before relinquishment (REL group) was significantly shorter if there were children in the household than if there were no children.
