Mr. Harris pleaded no contest to possession of pseudoephedrine for use in making methamphetamine. On appeal to the First District Court of Appeal, he challenged the reliability of the drug-sniffing dog used by the officer who stopped him. Mr. Harris argued the drugs seized from his truck could not be used as evidence because the officer lacked probable cause. The First District Court of Appeal upheld the trial court's ruling to allow the evidence and this appeal followed.
