Officer Joga, who began her training in cash detection when she was just four months old, is currently part of the mobile group of the Vilnius Territorial Customs. Her role involves checking vehicles at road posts, inspecting postal shipments, and examining luggage at airports. The article emphasizes her extensive experience in cash detection, highlighting that her skills are regularly enhanced through participation in police-organized courses that culminate in tests and certifications, as well as regular training sessions with her canine partner.

As part of her ongoing training, real cash is crucial for the drills, especially since old banknotes tend to lose their scent over time. Therefore, the customs office needs to continually refresh its training materials, similar to practices in drug detection. The Bank of Lithuania assists customs by providing decommissioned banknotes, which, although cut, are still utilized for training to keep the dogs' ability to detect cash sharp.

Interestingly, the dogs are trained to respond not to the face value but to the chemical composition of the ink on the banknotes. This means that whether it is a €5 or €500 note, the scent remains unchanged due to the same ink formulation used. In contrast, other currencies, such as US dollars, are noted to have a stronger scent, posing different challenges in training exercises, which require adaptations for varying currency types.
