: This study was carried out on blood samples provided voluntarily by dog owners; thus no ethical approval/licence was required for this study (as per Resolution on the protection of animals used for scientific or educational purposes, 15th January 2015 [Dz. U. 2015 position 266] Chapter 1, Paragraph 1.2.1). The owners of dogs involved in this study were informed of the aim of the study and provided oral consent and contact information to obtain the results of testing. No wolves were specifically killed for this study. The Polish General Directorate approved the collection of samples for Environmental Protection (DZP-WG.6401.08.1.2017.bp). Permission for wolf capture and handling was granted by the Polish Ministry of Environment for field work conducted within Roztocze National Park (DOP-WPN.286.309.2018.MD) and the Regional Directorate for Environmental Protection in Lublin for field work outside the national park (WPN.6401.18.2020.KC). All procedures were approved by the First Warsaw Local Ethics Committee for Animal Experimentation in Warsaw (ethical licence numbers: 759/2018, 977/2020) according to the principles governing experimental conditions and care of animals required by the European Union and the Polish Law on Animal Protection.
