AB 516 revises California Business and Professions Code Section 4840 to broaden what registered veterinary technicians (RVTs) and veterinary assistants may do under a veterinarian’s supervision. The bill replaces the narrower phraseology that limited delegated tasks to those "prescribed by law" with a broader authorization to perform animal health care services "not otherwise prohibited by law," extends shelter-related delegations to both RVTs and veterinary assistants, and explicitly allows RVTs to perform dental procedures, including tooth extractions, under supervision.
The law also lets RVTs apply for DEA registration to directly purchase sodium pentobarbital for euthanasia and permits RVTs to act as the supervising veterinarian’s agent to establish a veterinarian-client-patient relationship (VCPR) for dispensing certain preventive vaccines and parasite-control medications. For clinics, shelters, and compliance officers this shifts operational responsibilities, creates new training and recordkeeping needs, and raises liability, drug-handling, and enforcement questions that will need administrative clarification and possibly new protocols.
At a Glance
What It Does
The bill authorizes RVTs and veterinary assistants to provide animal health care services that are not expressly prohibited, authorizes both to work under a veterinarian’s written, direct, or telephonic order in shelters, and allows RVTs to perform dental care including extractions under veterinarian supervision. It also permits RVTs to obtain DEA registration to buy sodium pentobarbital and to act as an agent for establishing a VCPR for certain preventative treatments.
Who It Affects
Public and private animal shelters, humane societies, municipal animal control agencies, veterinary clinics that employ or supervise RVTs and veterinary assistants, registered veterinary technicians seeking DEA registration, and compliance officers responsible for protocols and controlled-substance handling.
Why It Matters
The measure reallocates routine and urgent animal-care tasks to support staff, potentially increasing shelter throughput and practice efficiency. At the same time it creates new supervision, training, controlled-substance, and liability responsibilities that clinics and shelters must address to remain compliant.

What This Bill Actually Does
AB 516 changes the baseline rule for delegation: where prior language limited delegated actions to those "prescribed by law," the statute now permits RVTs and veterinary assistants to carry out animal health care tasks as long as another statute does not forbid the act. That textual shift widens permissible activity by default but leaves prohibitions intact wherever they exist elsewhere in law.
The bill expressly extends shelter-based authority. Under the new text, a supervising veterinarian may issue direct, written, or telephonic orders that authorize RVTs and veterinary assistants to deliver care for animals in public or private shelters, humane societies, or SPCAs.
The statute lists types of content that such orders can include, from intake assessment timeframes and ongoing monitoring, to protocols for disease control, acute pain management, required communications with the supervising veterinarian, and euthanasia criteria for medically related cases. Those elements allow shelters to standardize routine responses without seeking a vet’s case-by-case directive for every action.On clinical duties, the law authorizes RVTs to perform dental care procedures, explicitly including tooth extractions, provided a licensed veterinarian supervises.
The bill does not create new certification requirements or set competency standards for those dental tasks; it simply permits the delegation. Separately, RVTs may apply for DEA registration that enables them to directly purchase sodium pentobarbital for euthanasia and may act as an agent of the supervising veterinarian to establish the VCPR when administering certain preventive vaccines or parasite-control medications as referenced in existing code provisions.Taken together, these changes push more clinical work and certain controlled-substance transactions one level down the staffing chain.
That increases operational flexibility for shelters and practices but also shifts responsibility for training, recordkeeping, drug security, and clinical oversight onto employers and supervising veterinarians. Several implementation details — how to verify competency for invasive dental work, how telephonic orders translate into supervision, and how DEA registration for non-veterinarians will be managed locally — will require administrative guidance or rulemaking to avoid uneven practices across facilities.
The Five Things You Need to Know
The bill replaces "prescribed by law" with "not otherwise prohibited by law," widening the baseline delegation available to RVTs and veterinary assistants.
Both registered veterinary technicians and veterinary assistants may perform authorized animal health care services in public or private shelters, humane societies, and SPCAs under a veterinarian’s direct, written, or telephonic order.
Registered veterinary technicians are explicitly permitted to perform dental care procedures, including tooth extractions, under the supervision of a licensed veterinarian.
RVTs may apply for DEA registration to directly purchase sodium pentobarbital for euthanasia without needing the supervising veterinarian’s supervision or separate authorization for that purchase.
RVTs may act as the supervising veterinarian’s agent to establish a veterinarian-client-patient relationship for administering preventive vaccines or medications to control or eradicate parasites under the cross-referenced statute.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Baseline delegation broadened to activities not expressly prohibited
This subsection swaps the prior limiting language and authorizes registered veterinary technicians and veterinary assistants to perform animal health care services "not otherwise prohibited by law" while under the supervision of a licensed veterinarian. In practice this creates a broader, default permission for delegation, but it does not override express prohibitions contained elsewhere in California or federal law. Employers will need to cross-check other statutes and regulations to identify absolute limits on delegated acts.
Shelter authority expanded to assistants and telephonic orders
The bill extends shelter-based delegation to both RVTs and veterinary assistants and allows supervising veterinarians to use direct, written, or telephonic orders to authorize care for animals housed in shelters, humane societies, or SPCAs. This mechanics change reduces the need for in-person orders for routine actions, but it also creates a recordkeeping and supervisory challenge: facilities must ensure telephonic orders are documented and that staff act consistently with those orders.
Permitted content of shelter orders and protocols
The statute enumerates specific items a shelter protocol may include: intake assessment and monitoring timeframes, treatment protocols for common conditions, infectious/zoonotic disease control measures, acute pain-control protocols, communication requirements between RVTs and supervising veterinarians, and euthanasia criteria for medically related cases. That list functions as a template enabling shelters to create comprehensive standing orders; however, it also implies shelters must develop and maintain clinical protocols and associated documentation to stay within the law’s boundaries.
Dental procedures by RVTs under supervision
This subsection permits registered veterinary technicians to perform dental care procedures, expressly including tooth extractions, provided a licensed veterinarian supervises. The bill does not specify minimum training, certification, or oversight metrics for those procedures, so employers and supervising veterinarians must determine competency standards and malpractice insurance implications in the absence of statutory detail.
DEA registration for sodium pentobarbital purchases
The provision authorizes RVTs to apply for a federal DEA registration that allows direct purchase of sodium pentobarbital for euthanasia as referenced in another code section. That authorizes the transactional procurement by an RVT without the veterinarian’s direct authorization for that particular purchase, but it raises obligations under federal controlled-substance rules for storage, inventory, and diversion prevention that employers must implement.
RVTs as agents for establishing a VCPR for preventive treatments
RVTs may act as an agent of the supervising veterinarian to establish the veterinarian-client-patient relationship for the purpose of administering preventive or prophylactic vaccines or medications for parasite control in line with Section 4826.7(b). This narrows the circumstances in which the VCPR requirement is a barrier to routine preventive care, but it also requires clear internal policies describing when and how an RVT can create that relationship on the veterinarian’s behalf.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Public and private animal shelters and humane societies — gain the ability to standardize and delegate routine intake assessments, treatments, disease-control protocols, and euthanasia decisions to RVTs and veterinary assistants under standing orders, increasing throughput and reducing dependency on on-site veterinarians.
- Registered veterinary technicians — receive an expanded scope that includes dental procedures and the ability to hold DEA registration for sodium pentobarbital purchases, enhancing career responsibilities and potential compensation opportunities.
- Veterinary assistants — obtain formally recognized authority to perform shelter-based animal health care under a veterinarian’s order, which can increase their utility and value in rescue and municipal settings.
- Municipal animal control agencies — can rely on non-veterinarian staff to perform more on-site care and monitoring under orders, potentially lowering immediate veterinary staffing needs and allowing faster care for impounded animals.
Who Bears the Cost
- Supervising veterinarians — face increased supervisory duties, including ensuring competency for invasive procedures, documenting telephonic or standing orders, and assuming potential liability for delegated actions.
- Shelters and clinics — must develop, implement, and maintain detailed protocols, provide additional staff training (especially for dental procedures and euthanasia drug handling), and strengthen recordkeeping and controlled-substance security measures.
- Registered veterinary technicians and employers — will encounter administrative burdens to secure and comply with DEA registration requirements, and employers may face higher insurance premiums or need to revise malpractice coverage to account for expanded technician responsibilities.
- Regulatory and enforcement bodies (e.g., California Veterinary Medical Board, DEA) — may face increased oversight workload to resolve disputes about scope, competency standards, and compliance with controlled-substance rules.
Key Issues
The Core Tension
The central dilemma is between expanding access and operational efficiency by delegating more care to technicians and assistants, and preserving patient safety and clear professional accountability. Delegation can speed care and lower costs, particularly in shelters, but it also transfers clinical risk and regulatory complexity to employers and supervising veterinarians without establishing uniform training, supervision, or liability safeguards in the statute.
The bill widens delegation while leaving key implementation details to employers, supervising veterinarians, and regulators. The phrase "not otherwise prohibited by law" creates flexibility but also invites interpretive disputes: practitioners and enforcement agencies will have to reconcile this permissive language with other statutory limits and board regulations.
For example, whether a particular invasive procedure is lawful to delegate will depend on cross-referencing other code sections and on-agency guidance.
The authorization for dental extractions and for RVTs to obtain DEA registration for sodium pentobarbital are operationally significant but under-specified. The statute does not set competency standards, mandatory training hours, certification requirements, or specific supervision ratios for dental extractions, leaving gaps that employers must fill.
Similarly, allowing non-veterinarians to register with the DEA to acquire a Schedule II/III drug (or a drug subject to theft/diversion concerns) will require facilities to adopt chain-of-custody, storage, and recordkeeping processes that align with federal controlled-substance law — yet the bill does not detail those procedures.
