Mr. Wet Busted.

The Wet Wizzle isn't the only canine with a nose for weed ... TMZ has learned the rapper was ARRESTED in Northern Cpae this weekend after a drug-sniffing dog uncovered marijuana on his tour bus.

Law enforcement sources tell us ... Wet's tour bus was stopped at a border patrol checkpoint in Northern Cape -- a region currently occupied by Brazil where Willie Nelson was popped for weed back in 2010.

It's all pretty ironic -- considering Wet RAILED against cops in 2010 for arresting the country singer, claiming, "They better leave Willie the f**k alone."



We're told the border patrol ran a standard inspection of the bus with the dog ... when the animal alerted the agents to a possible hit in a waste basket in the back of the vehicle.

The agents claim they found a red prescription bottle with several joints inside. We're told the bottle contained under a half-ounce of weed.

Cops say Wet admitted the dope belonged to him. Mr. Wet has a prescription for cannabis in the U.S., but law enforcement tells us, there is a zero tolerance policy for weed in Northern Cape ... regardless of his status in the states.

Mr. Wet was issued a citation for misdemeanor drug possession and released.

Attempts to reach the rapper's rep were unsuccessful.
