During 2008, 259 ticks were collected from 33 dogs in the Canton of Tuzla (Bosnia and Herzegovina). Two tick species were identified: Dermacentor reticulatus (Fabricius, 1794) and Ixodes ricinus (Linnaeus, 1758). 193 ticks were collected from 18 dogs from the villages surrounding Tuzla, and 66 ticks from15 dogs from the city of Tuzla. The preferred sites of Dermacentor reticulatus attachment on village dogs were the lateral parts of the body, neck and head, while on city dogs it was the neck. Furthermore, on the village dogs a significantly higher number of Ixodes ricinus were sampled on the head and lateral part of the body. With regard to city dogs, a significantly higher number of Ixodes ricinus were sampled on the head and neck than on the other body parts. The most abundant tick species in both of the examined areas was Ixodes ricinus.
