A Pacoima man on probation for — you guessed it — a narcotics rap was stopped by the wrong cop this week.

Because Officer Jonathon Miller of the Fullerton Police Department brought along Mueller, a drug-sniffing dog eager for his first big bust.

The pooch went to work, and cops say he found about $1 million worth of cocaine — 20 kilos — in the suspect's car, Fullerton PD announced this week. Thasa good boy.

It all went down Tuesday …

… near Magnolia and Orangethorpe avenues in Fullerton when Miller spotted the suspect behind the wheel of a Chevrolet Monte Carlo. After the officer learned the driver, later ID'd as 28-year-old L.A. man Alfonso Cisneros, was on probation, operation sniff-'em-out was on.

Mueller, a German shepherd donated to the department in December, alerted to the trunk area and, alas, white gold, cops claim. It was Mueller's first big bust, they say.

Cisneros was booked and jailed in lieu of $3 million bail.

The lesson? Have your girlfriend drive your load. She'll be much less suspicious. And don't by any means use a Monte Carlo to transport $1 million worth of yay. A Monte Carlo just screams criminal. (Cop just knew his cruiser's laptop was going to ping when he ran its plate, right?).

We kid. Well, not about the Monte Carlo.
