Were my rights violated?

I was arrested for Criminal Trespass and Possession of Meth. I pulled down the driveway of an old farmhouse. I got to the house sat there for 5 seconds,never got out,,and started to backup and there was a Putnam county sheriff behind me. He got me out of my car and handcuffed me and put me in his car. The first thing he asked me was "Where is the Meth?" While we were sitting there a K9 unit shows up and without asking if they could search my car he walked the dog around it. He said I was under arrest, never read me my rights and took me to jail. I don't see how he had probable cause to search my vehicle for Meth just because I pulled down a driveway and never got out and was getting ready to leave before I noticed he was there. He obviously seen that I never got out of my car.
