Just three months after being deployed in the Pilbara, Western Australia's first dual general purpose and narcotics dog has rounded up armed offenders, domestic violence perpetrators, drink drivers and illegal drugs.

And there could be as many as seven more dogs just like him on the way soon, as WA Police revamp the way it trains their invaluable canines.

Maygar became the very first dual general purpose and narcotics police dog to join the force earlier this year.

He arrived in the Pilbara with his handler - First Class Constable Tom Gryta - in September.
