Who's a naughty little stowaway? Is it you? Is it you? Yes it is! You're the naughty little stowaway who was found in a traveler's suitcase this week at New York's LaGuardia Airport.

According to TSA spokesperson Lisa Farbstein, the furry freeloader was discovered after the checked suitcase set off an "unknown-contents alarm." The unknown contents, it turned out, was this tiny doggie who snuck into his owner's bag while she packed. From the agency's Instagram:

Ay, #Chihuahua! It's always important to double check your bags before traveling, especially to make sure your Chihuahua hasn't stowed away inside one of them. That's exactly what happened this week at #NewYork's #LaGuardia (#LGA) Airport. While resolving a checked baggage alarm, an officer was shocked when he found a dog in the bag! Apparently, the dog climbed in while its owner was packing her suitcase. TSA worked with the airline to identify the owner, and the two were happily reunited. #DogsOfInstagram #TSAGoodCatch

I, for one, believe the owner's story. I mean just look at this devious little sneak thief.
