 Aldo is trained and certified to detect cannabis, cocaine, ecstasy, heroin, and methamphetamine – he is not trained to detect alcohol or pseudoephedrine.Although pseudoephedrine is a precursor to methamphetamine, there was no testimony as to whether a dog trained to detect methamphetamine would also detect pseudoephedrine.Officer Wheetley and Aldo were partnered for a year before the Harris stop, and they completed an annual forty-hour training seminar four months prior to that stop.
