Since previous research shows that pets are considered to be important members of the family today, the aim of this paper is to determine the impact they may have on socioemotional development of children. Many research on this subject has shown the positive effects that pets can have on children who grow up with them. It is considered that, as a child can develop attachment to people from the environment, it is also possible to develop that with pets. Therefore, questioning the relationship between a child and a pet is the main starter of any research on this topic. Some of them found that the quality of relationships that the child achieves with their pets is essential to the development of child empathy and social skills, which are one of the main components of the socioemotional development. The research results in this paper show that the child's emotional relationship with pets is more intense in girls than in boys, which is consistent with previous research results. Furthermore, it has been shown that there is a connection between the pet´s possession and the emotionality of children and their socioemotional relationships. There are certain limitations of this questionnaire, but some particles with significant gender differences or pet ownership can be used in future research on this topic. It is also necessary to include other factors that can play an important role in defining the effect of the pet on the child, for which many detailed studies are required.
