This research determined the influence of a female scent placed in male selective sequence on the indications of dogs trained in identifying human scent traces.
Abstract
The study found that regardless of the methods used in testing, dogs used in identifying human scent traces did not limit the range of their choices of scents from a selective sequence due to the sex of a person. This indicates that the dogs had a clear preference for the scent of the targeted persons regardless of the person's sex. The study determined that the factors that had the most influence on the number of incorrect indications by the dogs were the lack of motivation by the dog for scent work in given circumstances and poor training. The study was conducted at the laboratory of olfactory traces of the Department of Forensic Techniques at the Police Training Center in Legionowo, Poland. The two objectives of the study were to determine whether a female scent placed in a male selective sequence was attractive for specially trained dogs, as well as to determine whether a female scent that the dogs were given to sniff was the connection between it and the scent of another woman placed in a male selective sequence and whether it caused false positive indications by dogs. Twenty-two police dogs participated in the study. All of the dogs had completed two courses of retraining and certification of dogs used for the identification of human scent traces. Research procedures are described in detail. 6 tables and 10 references
