> You don't wanna start the stop off on the wrong foot by being that "am I being detained" jerk right from the get go. You should not give up your rights but it's not generally helpful to assert that you know them until they probe to see whether you do.

Right, that's why it's step 3 and not step 1

> It might work out for you, but maybe the K9 guy is an asshole and the cop wants to make him drag his ass across town for no good reason. Don't be his reason.

You are missing the point by a mile: K9 searches are voluntary. If a cop feels they have a reason to arrest you they will just arrest you. If they feel they have enough evidence to search your car they'll just search it.
