When the cops unzipped one of the luggage, they were appalled by what they discovered inside after the service dog started barking loudly and aggressively 
Nobody was shocked when the service dog entered the airport premises. She was like an employee, serious, focused, and performing her work more effectively than some others. Everyone had long since grown accustomed to her.
Even though others longed to scratch behind her ear or pet her friendly muzzle, nobody dared approach her in the slightest.
It’s out of respect, not fear, that you don’t divert the dog. The handler strolling next to her received, at most, a faint smile.
However, the serenity abruptly ended when the officers with the dog turned to face the cargo terminal.
Without waiting for an order, the dog abruptly halted, took several deep breaths, and started toward one of the luggage that were traveling along the conveyor belt. The handler scowled; she hardly ever had such a sudden reaction.
With its faded fabric, straps, and typical departure sticker, the luggage bore a striking resemblance to hundreds of others. At first look, nothing seems odd.
However, the dog seemed to turn to stone as it froze in front of it. She didn’t blink as she looked directly at the case. The handler saw right away that there was something prohibited within. The dog is error-free. Never.
One officer walked closer and observed little holes along the borders – as if someone had poked the bag with something sharp.
The dog shuffled uncomfortably, nearly trembling — she behaved this way only to something really serious…
The officer quickly ordered, “Open the bag.”
One of the policemen put on gloves and carefully burst the seal.
The dog immediately took a step back and gave a low growl when the luggage was eventually opened, not out of fear but out of anticipation. Because inside the bag was… 
There were no common objects found by border guards inside, nor were there any live things. The cops turned pale, however, at the discovery.
A painting was hidden beneath layers of bubble wrap. Not just any artwork, but the very one that had made headlines a week prior.
Missing from a private collection, the stolen masterpiece from the 19th century is valued at millions of dollars.
The handler let out a breath:
She behaved in that way because of this. paint and solvent odors, remnants of the storage location, etc.
The dog appeared to be saying, “Found it,” as it examined the case. Do your work now.
