ABSTRACT=<p>In 2021, a case of canine brucellosis diagnosed in a dog with orchitis was presented to a veterinary practice in Germany. Serological testing excluded <italic>Brucella</italic> (<italic>B</italic>.) <italic>canis</italic> as a causative agent, but molecular analysis revealed the presence of <italic>B. suis</italic> biovar 1. Since biovar 1 is not endemic in Europe and the dog had no history of travel to endemic areas, a comprehensive epidemiological investigation was conducted using whole genome sequence data to determine the source of infection. We describe the clinical progress of the animal and the potential infection of a veterinary clinic employee. The findings highlight the importance of considering less common <italic>Brucella</italic> species as possible causes of canine brucellosis. The data also emphasize that it is quite challenging to identify <italic>Brucella</italic> species in a routine diagnostic laboratory and to conduct epidemiological investigations to unveil possible transmission routes.</p>
