AB 400 California Assembly · 2025-2026 Regular Session

Commission on Peace Officer Standards and Training: police canines.

Summary
Existing law establishes the Commission on Peace Officer Standards and Training within the Department of Justice and requires the commission to, among other things, develop and disseminate guidelines for all peace officers in California. This bill would require, on or before July 1, 2028, the commission to study and issue recommendations to the Legislature on the use of canines by law enforcement. The bill would require the commission to consider in its recommendations, among other things, instances of appropriate patrol use with a canine, as specified, and instances of appropriate use with a canine for detection, as specified. The bill would repeal these provisions on July 1, 2031.

MODERATE
The September 5 amendment made two substantive changes to AB 400: it extended the deadline for the Commission on Peace Officer Standards and Training (POST) to complete its canine use study from July 1, 2027 to July 1, 2028, and it removed an entirely separate section that had required local law enforcement agencies with canine units to adopt written canine use policies by January 1, 2027. The removal of that local agency mandate also eliminated the state-mandated local program designation and the associated reimbursement provisions.
TIMELINE

The deadline for POST to study and issue recommendations on canine use was extended from July 1, 2027 to July 1, 2028, giving the commission an additional year.

SCOPE

Section 13671 was removed in its entirety. This section had required every law enforcement agency with a canine unit to maintain a written canine use policy that complied with POST standards by January 1, 2027. Its removal means the bill no longer directly mandates local agencies to adopt such policies.

The bill title and digest were narrowed to focus solely on POST rather than also referencing law enforcement generally, reflecting the removal of the direct local agency requirement.

FISCAL

The state-mandated local program designation was changed from 'yes' to 'no,' and the reimbursement section (SEC. 2) referencing the Commission on State Mandates was removed, consistent with eliminating the cost-imposing mandate on local agencies.
