<p>The impact of invasive species is recognized as one of the major threats to global biodiversity, with carnivorous animal species implicated as some of the most detrimental. Since their deliberate introduction into Europe in the early twentieth century, the raccoon dog (<i>Nyctereutes procyonoides</i>) has become one of the most common mesocarnivores on the continent, with far- reaching implications for native species. Previous reviews by Kauhala and Kowalczyk in 2011 and Mulder 2012 described the history and invasion of <i>N. procyonoides</i> in Europe, including features behind their invasion success, and the then scarcely understood impacts on native fauna. Our aim was to provide an update on the current status of alien raccoon dog populations not only in Europe, but in Asia as well, focusing on additional research which has been published on the factors contributing to the success of this species in regions of introduction, their effects on native species through competition for spatial and dietary resources, predation, as well as the spread of established and emerging parasites and pathogens. Current surveillance and control methods, and their efficacy, are also discussed. This review highlights the need for additional monitoring and control strategies of <i>N. procyonoides</i> as their invasive range continues to expand, and the negative impacts on native fauna become increasingly apparent.</p>
