The head of Western Australia's anti-corruption body has slammed the use of police dogs on young people, telling a parliamentary committee the policies governing the use of police dogs were "not racist in intent, but are racist".

In November 13-year-old Indigenous boy Jayden Abraham was mauled by a police dog after disturbances were reported in the south east of Perth.

Days after the attack, the Aboriginal Legal Service of WA noted that the majority of people, including children, who have been injured by police dogs in recent years have been Indigenous.

Appearing before a Western Australian parliamentary committee on Wednesday, Corruption and Crime Commissioner John McKechnie used his opening statement to raise concerns about WA Police's use of dogs.

"The word complex does not begin to describe the issue of juvenile offending and its causes and solutions are difficult," he told the committee.

"But at the end of the day, are we a people who are content to unleash dogs on children? I think we're better than that."

The CCC found 61 per cent of all police dog deployments in 2020/21 were targeted at Aboriginal and Torres Strait Islander people.

Mr McKechnie said while all allegations of serious misconduct were reviewed by the Commission, it was often "difficult" to verify those claims when officers were "substantially" following procedures.

The former Supreme Court justice said his main concern was about the broader policies governing the use of canines.

"The present policies are not racist in intent, but are racist… Many deployments are against young and or Indigenous persons," he said.

Speaking outside the committee later on Wednesday Mr McKechnie questioned the efficacy of police dogs.

"We really need to address the causes of that offending and simply locking people up and simply letting dogs loose is not going to affect it," he said.

He told the ABC that Police Commissioner Col Blanch was "actively working on the issue".

"I don't think he's actively opposing it, he's trying to seek a solution like many people are to the problems that lead to Banksia Hill and lead to this," Mr McKechnie said.

In a statement, a WA Police spokesperson told the ABC the force worked closely with the CCC regarding the use of police dogs.

"Further to this, WA Police Force reviews policies and procedures as part of normal duties in order to ensure the best and safest outcomes for the community," they said.

"The ability for an officer to use force, including deployment of a police canine, is carefully considered and the subject of frequent training and review.

"Officers are generally using force in dynamic and dangerous situations, and are making these decisions in a matter of seconds."

As at the end of November 2022, Aboriginal Legal Service WA had advised 38 clients who had been mauled by police dogs over the preceding decade. Twelve of the clients were children at the time, including a boy who was just nine years old. The victims also included a vulnerable woman who was bitten on the head, a man bitten on the face while handcuffed, and a mentally unwell man who was already in police custody when mauled.

ALSWA said the available data demonstrates police disproportionately use dogs against First Nations peoples.

Figures provided by the legal service showed that between 2018-2021 First Nations people made up 53 per cent of all people injured by police dogs. 20 per cent of all people injured were children and 65% of those children were First Nations children.

The data provided by ALSWA for 2020-21 confirmed that 61% of police dog deployments were against First Nations people.

ALSWA said it was aware of 34 children who have been injured by a police dog since 2015 and 23 of these children were recorded as First Nations children.

WA Police Minister Paul Papalia told the ABC that police rarely knew who they were pursuing.

"It's often at night time, in the dark, and people are only apprehended by police dogs if they've failed to stop when they've been given a warning and they continue to represent a threat," he said.

"So, I support police dogs and the use of police dogs under our current policy. Police dogs stop crime."
