The two corpses of police dogs, of Labrador retriever breed used for fi nding narcotics, were sent to the Scientifi c Veterinary Institute “Novi Sad”, and examined post-mortem, in order to determine the cause of death. Post-mortem examination revealed the presence of neoplastic changes in
the mandibular region, pulmonary parenchyma and axillary region. The samples of neoplastic changes were sent to the Laboratory of Patohistology
within the Faculty of Veterinary Medicine, University of Belgrade, in order to specify the diagnosis. Histopathology examination revealed an adenocarcinoma in lungs and haemangioendothelioma in axillary region. Is there any role of drug sniffi ng on the occurrence of neoplasia in Labrador retriever breed is still unknown, but it could be an important factor in the development of neoplasia in these dogs.
