As I was sitting near the gate waiting for my flight to start boarding, I saw security walking around with a dog, I assume trained to sniff out explosives. The dog was VERY interested in my backpack and returned again and again to sniff. I was fully expecting the security officer to ask to search my bag but he finally scolded the dog to "LEAVE IT!" The dog was apparently sniffing the scents of the 4 cats and 1 dog that I have at home since I didn't have any food in the bag. I am guessing that if the dog actually smelled something suspicious, he would bark and that is why the security officer knew it was something innocent.
