Brown dog tick found in UK on dog with no travel history.

Brown dog tick detected in UK dog without travel history; unprecedented finding requiring heightened surveillance.

This case report documents the first identified presence of Rhipicephalus sanguineus (brown dog tick) in the United Kingdom on a domestic dog with no history of travel outside the country. Brown dog ticks are typically associated with warmer climates and are not established in the UK. The case highlights the importance of thorough clinical examination and parasite identification in dogs presenting with tick infestation. The detection of this non-native tick species raises concerns about potential establishment of new tick populations in the UK and the associated health risks, including transmission of pathogens such as Babesia canis and Ehrlichia species. The authors emphasize the need for increased awareness among veterinary practitioners regarding non-native tick species and recommend proper identification of ticks to detect any potential epidemiological changes. This finding has implications for tick surveillance programs and suggests that exotic tick species may be establishing populations in UK environments. The case underscores the value of reporting unusual parasitic findings to support ongoing epidemiological monitoring and public health surveillance.
