AB 400 adds Penal Code section 13514.7, directing the Commission on Peace Officer Standards and Training (POST) to study the use of canines by law enforcement and deliver recommendations to the Legislature by July 1, 2028. The statute lists specific subjects POST must examine — from patrol and detection roles to factors for reviewing canine-related use-of-force incidents — and requires the report to follow state report rules; the provision itself is set to repeal on July 1, 2031.
For agencies and compliance professionals, the bill is a signal: the state wants a centralized, evidence-based set of recommendations on how, when, and under what controls police canines should be deployed. While the bill creates no immediate statewide mandates, the POST report could shape future training requirements, model policies, metrics for after-action review, and legislative follow-ups that carry operational and budgetary consequences for local departments.
At a Glance
What It Does
Creates Penal Code section 13514.7 requiring POST to study police canine use and deliver recommendations to the Legislature by July 1, 2028; the section sunsets July 1, 2031. The report must address enumerated topics and comply with Government Code reporting rules.
Who It Affects
Local and county law enforcement agencies that operate canine units, canine handlers and trainers, municipal training divisions, civil rights and animal welfare organizations, and lawmakers who may act on POST’s recommendations.
Why It Matters
POST’s recommendations could become the blueprint for future statewide standards or legislation on canine deployment, training, and incident review. Departments should anticipate policy alignment, potential training changes, and new data or reporting expectations if the Legislature adopts follow-on measures.

What This Bill Actually Does
AB 400 instructs POST to perform a focused study and return a set of recommendations about law enforcement use of canines. The deadline is explicit: POST must submit its findings and recommendations to the Legislature no later than July 1, 2028.
The statutory direction is time-limited because the section automatically repeals on July 1, 2031, which makes the requirement a discrete project rather than a permanent new duty.
The bill lists six topic areas POST must consider. These range from high-level principles — that canine deployment is a community concern and must safeguard life and dignity — down to operational items: standards for patrol deployments (obedience, search methods, apprehension, handler protection), standards for detection work (control, alert behavior, odor detection), factors to use when evaluating canine-related uses of force, and measures to protect public, handler, and canine safety such as warning practices before releasing a dog.
The statute also requires that officers carry out duties relating to canines in a fair, unbiased manner.On the mechanics side, the bill ties the report to Government Code procedures (Section 9795), so POST will need to follow established formatting and submission steps used for legislative reports. The text calls for recommendations, not for immediate rulemaking or binding standards; POST’s output will be advisory unless and until the Legislature or another body converts recommendations into mandatory law or certification requirements.For practitioners, the key operational consequence is anticipatory: departments that run K-9 units should expect a consolidated set of best practices or review criteria to appear in the report.
That means potential downstream work — updating local policies, retraining handlers, changing record-keeping for canine incidents, and budgeting for implementation if the recommendations are adopted. The bill contains no dedicated funding, so implementation costs would fall to agencies or require separate legislative appropriation.
The Five Things You Need to Know
POST must study and submit recommendations on law enforcement canine use to the Legislature by July 1, 2028.
The statute lists six required consideration areas, including principles safeguarding life and dignity; bias-free conduct; patrol standards (obedience, search, apprehension, handler protection); detection standards (control, alert, odor detection); factors to evaluate canine use-of-force incidents; and safety measures such as warnings prior to deployment.
The required report must be prepared in compliance with Government Code Section 9795 (state report submission requirements).
The added Penal Code section is temporary: it is set to repeal automatically on July 1, 2031 under Government Code Section 10231.5.
The bill directs recommendations only — it does not itself create binding operational standards, change certification law, or provide implementation funding.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
POST study and deadline
This subsection establishes POST’s core assignment: study police canine use and send recommendations to the Legislature by July 1, 2028. Practically, POST must scope a research and stakeholder process that produces actionable recommendations within a three-year window, which will force choices about evidence collection methods, public input, and coordination with local agencies that operate K-9 units.
Principles: community concern and bias-free use
The first two items require POST to frame recommendations around two bedrock principles — that canine deployments implicate community trust and that officers should protect life, dignity, and liberty without prejudice. Framing recommendations this way signals that POST should evaluate tactics not only on tactical effectiveness but on civil-rights impacts and procedural fairness, which may push the report toward accountability measures (e.g., reporting, documentation, oversight) as well as training changes.
Operational standards for patrol and detection
These subsections identify concrete operational topics POST must cover: for patrol work, standards for obedience, search technique, apprehension, and handler protection; for detection work, standards for control, alert behavior, and odor detection. That split matters: detection deployments (narcotics, explosives) and patrol/apprehension uses have different risk profiles and training metrics, so the report will need tailored performance measures, certification benchmarks, and possibly separate training curricula.
Use-of-force review factors and safety/warning practices
POST must propose factors for evaluating and reviewing all canine use-of-force incidents and address other safety considerations, including how to warn a suspect within a deployment area before releasing a canine. Operationalizing these items will require POST to recommend definitional thresholds (what qualifies as a canine use-of-force), documentation checklists, after-action review protocols, and guidance on warning content and delivery methods that balance officer safety and suspect notice.
Report compliance and sunset
Subsection (b) ties the report to Government Code reporting standards and makes the statute temporary, repealing it on July 1, 2031. The procedural tie-in means POST must follow standard state report formatting and filing steps; the sunset limits the statutory obligation to a single-cycle study and report unless the Legislature acts to extend or replace it.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- People subjected to canine deployments — a POST-led study could produce clearer expectations, mandatory warning practices, and review criteria that reduce arbitrary or biased deployments and improve transparency when incidents occur.
- Local policymakers and city/county counsel — the report provides a consolidated evidence base and model language they can use to update municipal policies and reduce legal uncertainty across jurisdictions.
- Canine handlers and departments — clearer, statewide guidance on training, obedience, detection standards, and incident review can reduce liability, improve safety for handlers and dogs, and standardize certification expectations across agencies.
- Civil rights and animal welfare organizations — the focused study creates a formal venue to surface concerns and technical recommendations about humane treatment, accountability, and civil liberties tied to canine use.
Who Bears the Cost
- POST — must allocate staff time and research resources to meet the statutory deadline; without earmarked funds, the agency will need to re-prioritize other work or seek appropriations.
- Local law enforcement agencies — if the Legislature or POST’s recommendations lead to new training, reporting, or equipment standards, departments will face implementation costs for retraining handlers, updating policies, and tracking new incident metrics.
- Municipal and county budgets — adopting any recommended operational or reporting changes could require ongoing funding, increasing fiscal pressure on city and county general funds or requiring grant support.
- Legislators and oversight bodies — they bear the decision burden and potential political cost of whether to convert recommendations into binding law, which may trigger stakeholder pushback and demand budgetary offsets.
Key Issues
The Core Tension
The central dilemma is balancing officer and public safety against civil liberties and animal welfare: policymakers want canines available as effective law-enforcement tools, yet they also must guard against disproportionate force, biased deployment, and harm to people and animals; a study can map options, but any constraint that protects rights may reduce immediate tactical flexibility, and vice versa.
AB 400 is narrowly framed as a study-and-report mandate, which leaves two practical gaps. First, POST issues recommendations but cannot impose binding standards without additional rulemaking authority or legislative approval; the impact of the bill therefore depends on future action by the Legislature or POST’s own voluntary adoption into curricula.
Second, the statute includes no appropriation, so resource constraints could limit the depth of research, field visits, data collection, or stakeholder engagement that POST can conduct before the July 1, 2028 deadline.
Several implementation challenges are embedded in the bill’s enumerated items. Defining and measuring a "canine use-of-force incident" is not straightforward: the line between a routine apprehension and use of force that causes injury involves subjective assessments, inconsistent local reporting practices, and variations in training.
Recommending an effective warning practice that is both practical in high-risk deployments and meaningful to suspects raises operational trade-offs. Finally, the three-year sunset compresses the statutory window: it creates urgency but risks producing recommendations that lack the continuity or follow-up necessary to change long-term practice unless the Legislature or POST sequences additional steps.
