I think they only need probable cause. For instance, if they believe they smell marijuana or if a drug dog hits on the car.

And if the first dog doesn't hit, bring a second dog to the scene. Happened to me.

I had a dog trainer tell me that if the dog sits, doesn't sit,barks, doesn't bark, in short anything the dog does can be called a hit.

Well, maybe the first dog had a cold in his nose! ;)
