“…Detection dogs should work quickly, whilst not missing the intended targets nor exhausting themselves prematurely (Jezierski et al, 2014). In difficult terrain detection dogs should be agile, with exceptional stamina, allowing them to traverse the terrain (Rebmann et al, 2000;Hurt and Smith, 2009).…”

“…During police drug detection dog testing in Poland, German Shepherds had the highest accuracy and efficiency in comparison to Labrador Retrievers, English Cocker Spaniels and Terriers (Fox, Welsh and Jack Russell) (Jezierski et al, 2014). Terriers had the longest detection times and the highest proportions of false positives (Jezierski et al, 2014).…”

“…This has resulted in certain breeds being favoured for detection work. The current lack of breed comparative studies and the variation within each breed provides a challenge when selecting a suitable detection dog (Rooney and Bradshaw, 2004;Jezierski et al, 2014). If only individuals from one or two breeds are evaluated for their working potential, as is common in Military working dog programs (Moore et al, 2001;Sinn et al, 2010), this may restrict the detection program's success.…”

Trifluoromethyl‐Substituted Perylene Diimides for Rapid and Sensitive Film‐Based Fluorescence Detection of Methamphetamine and Cocaine Hydrochloride

Film‐based fluorescence sensors are attractive for rapid and on‐site detection of illicit drugs, due to their potential for portability, high sensitivity and reusability. Three new bay‐substituted perylene diimide derivatives are synthesized , P1‐CH3 (1‐methyl), P1‐CF3 (1‐trifluoromethyl), and P1‐(CF3)2 (1,7‐di‐trifluoromethyl) that can be solution processed into thin films capable of detecting methamphetamine hydrochloride (MA•HCl) and cocaine•HCl via a luminescence quenching mechanism. The ionization potentials of the materials are sufficiently high to enable photoinduced hole transfer to occur, which led to the luminescence quenching. The trifluoromethyl‐substituted PDIs exhibit superior sensitivity and reversibility of the luminescence quenching process. In particular, P1‐(CF3)2 shows a limit of detection to MA•HCl of ≈100 ng after a 15‐second exposure, and its luminescence can be fully recovered either through mild heating or being placed in an air flow. Furthermore, by using the luminescence quenching and recovery responses of four PDI sensing materials it is possible to differentiate MA•HCl, cocaine•HCl, from aspirin, caffeine, sugar, and (sebum) skin oil in around a minute.

Some effects of detection dogs on passenger behavior at border control ports

Detection dogs are used at border controls as an antecedent intervention to deter the smuggling of contraband. However, there is little research that has explored how the presence of dogs might affect passenger behavior. We observed passengers' behavior at a port when there was an officer alone, an officer with a dog, and an officer with a dog wearing a florescent yellow jacket with “police” written on it for increased salience. We measured eye contact, vocal‐verbal interactions, facial expressions, and nonvocal verbal gestures toward the officer and dog, and changes in passenger direction. Passengers looked, talked, and had the highest frequencies of positive facial expressions when the dog was not wearing a jacket. However, passengers looked toward the dog the quickest and had the highest frequency of negative facial expressions and gestures when the dog was wearing a jacket. We discuss how these findings might inform antecedent interventions to address undesirable behavior such as smuggling.
