The thing is, most cops aren't driving around with dogs. The way I read this ruling, in the absence of probable cause, the only way for a dog sniff to legally occur is if you are pulled over by a car that happens to have 2 officers and a dog in the car. One begins the ticket writing process, while the other simultaneously runs the dog around the car. This would cause no delay in the stop, and thus wouldn't violate this ruling. So Jay-Z only has 99 problems when he is pulled over by a K-9 patrol car with 2 cops in it. K-9 patrols are almost always clearly marked, so the moral is...drive carefully when you encounter one.
