Yes! I saw a presentation a couple of years back from police dog trainers. Different dogs would specialise in different things - drugs, guns, and amazingly - hard disks! They train them specifically to do so. What blew my mind was the reward was always just a tennis ball. But the dog was soooo happy to get the ball for a short amount of play when it did well.
Drug-sniffing dogs are a myth[1]. They're used as a pretext for illegal searches, not to detect drugs. I suspect this is similar. "Detecting off-gassing" is vague enough to sound like it makes sense, but there's a variety of materials in electronic devices and many of the ones that off-gas (like plastic) are found in millions of other products. 1. https://www.abc.net.au/news/2018-12-03/fact-check-are-drug-d...
