A Canberra police officer being investigated for pepper-spraying a chained dog has been removed from frontline duties.

CCTV footage taken from a house raid in May, apparently showed the officer using pepper spray on the dog before throwing a stick at it.

The dog's owner, who was not home at the time, made a formal complaint to police.

In a statement last week, ACT Policing said it did not condone cruelty to animals.

The matter is being investigated by Australian Federal Police (AFP) Professional Standards.
