Oh man if only we were hooked up to some kind of thing that had like answers to all our questions. Like the infonet or something
A detection dog can be trained to detect anything with a signature scent. The options are endless.

Dogs in airports can be trained for many things, although they are primarily trained to detect drugs, explosives or food. It is illegal to import certain kinds of food. At our airport, there is a beagle that detects 15 types of food, and a Griffin that detects explosives.

Dogs are NOT cross trained for drugs and explosives, it is one or the other. Items can retain the scen to drugs for a long time. If the explosive items or the package it is in had an odor of drugs, the dog could incorrectly signal as drugs. Not really a great idea.

Fucking hell
Griffins that detect explosives?

I want a centaur that can find truffles, and a unicorn that knits beanies.

Would the unicorn use it's horn as a needle?
Surely you'd need two working in harmony to knit something like a beanie.
