Ethics approval

: No animal was sacrificed for the purposes of this study. CWD blood samples were collected by veterinaries, from animals in healthy conditions, with the permission and assistance of the owners, minimizing any possible stress. The dog owners also authorised the data obtained from their animals to be used in this study, while maintaining their identity confidential.Wolf tissue samples were collected from eight Western Ukrainian, three Slovakian and one Polish wolves [CitationRef removed]. Tissues were collected, for purposes other than this project, from animals found dead or legally harvested by hunters with special permission for the extraction of hunting species. No ethics permit was required since wolf sample collection involved only dead animals. All samples were collected by specialized technician personnel.
