Animal-assisted services are mediated or guided practices, programs and human services that incorporate specially qualified animals into therapeutic, educational and/or ameliorative processes aimed at enhancing the well-being of humans. They are an umbrella term that incorporates animal-assisted treatment, animal-assisted education and animal-assisted support programs. Therapy animals participate in animal-assisted services and can provide psychological, emotional and physical benefits to people they interact with. Dogs are the most common animals in these services. Research shows the positive impact of therapy dogs working with children and youth; hence therapy dogs are involved in working with beneficiaries who have different difficulties or problems in different environments. Therefore, they also participate in work with children and youth with behavioral problems. The aim of this paper is to provide a more thorough description of the field of animal-assisted services, specifically therapy dogs, and the possibilities of their integration in work with children and youth with behavioral problems. The phenomenon of the human-animal bond will be described, along with the theoretical basis of the bond and the positive influence of animals, especially on children and youth. Then, animal-assisted services, therapy dogs and behavioral problems of children and youth will also be described. An overview of research involving dogs in work with children and youth with internalized, externalized and addiction problems will be presented, as well as the possibility of including a therapy dog in social-pedagogical work. In conclusion, examples of good practices from abroad will be cited and, considering the lack of research in this area, examples from practice in Croatia will be presented.
