This article describes the different kinds of sniffer dogs and their use in forensic investigation.
I’ve seen several comments here suggesting that the dogs hit at Wendy’s because they love hamburger. The dogs are more sophisticated than that.
Detection Dogs – The Forensics Library
“Canines detect odors directly from the source or residual scents; odors which persist in an area after the original source is no longer present.
Obviously the air is full of a vast variety of different odors, many of which will be powerfully clear to the dog. Fortunately they are able to distinguish between different odors, even if one smell overpowers another, and trace a specific scent to its source.”
The dogs tracked Brian’s scent (they were given items of clothing) from the back of the building (facing Pearl Alley) heading south. They hit on an area in the Wendy’s parking lot which was behind the building, also facing Pearl. This hit was on urine and/or vomit.
Cadaver dogs were also brought in to search the building. Here’s an interesting article on how these dogs are used by archaeologists to find ancient remains.
