This paper deals with the use of animals in social work as a form of dog-assisted interventions in the Mobile Youth Work. Animal-assisted interventions gain importance especially in the health and psychological context, but also the social work is increasingly focusing on this young field. Initially the Mobile Youth Work and its methods is adressed. This is followed by an overview of the forms of animal-assisted interventions and its numerous effects on humans, to then consider the dog-assisted intervention as a possible method of Mobile Youth Work. It should be illustrated, as a professionally inserted dog can support the Mobile Youth Work in achieving their objectives. But also the limitations of animal use should be disclosed. Finally, criticisms and existing challenges are presented.
