OPTIONAL: Paws for a moment: Investigation of bi-directional transfer of human DNA during a short human–dog interaction and subsequent indirect transfers

by Heidi Monkman, Roland A.H. van Oorschot, Mariya Goray, Science & Justice (2025)

From abstract: "Dog owner’s DNA transferred from the dog to the visitor and visitor related items and surfaces, including the car and the house, in 31 % of the samples. These results provide a valuable insight for forensic investigators on the potential origins of DNA found at a crime scene and also add to the body of research indicating that companion animals may be used as evidence to identify who had been in contact with a dog."
