AB 1458 adds two sections to the Business and Professions Code to permit licensed physical therapists to deliver “animal physical therapy” if they meet specific education, supervised-practice, and notification requirements. The bill defines two practice pathways: direct supervision by a veterinarian at a registered premises, or provision by referral under a written practice agreement and owner notice.
Beyond authorizing service delivery, the bill reallocates responsibility and regulatory oversight: it makes physical therapists solely liable for delegated animal therapy tasks, shields veterinarians from liability for therapy provided pursuant to their orders, requires cross-reporting between the Physical Therapy Board and the Veterinary Medical Board, and makes supervision failures a ground for discipline. Those shifts matter to clinics, insurers, licensing boards, and practitioners planning new service models or contracts.
At a Glance
What It Does
The bill allows California-licensed physical therapists who meet specified coursework, clinical training, and supervised-practice thresholds to perform animal physical therapy. They may practice either under a veterinarian’s direct on-site supervision at a registered premise or by referral under a written practice agreement and owner notification.
Who It Affects
Licensed physical therapists and their aides, licensed veterinarians and registered veterinary premises, the Physical Therapy Board and the Veterinary Medical Board, veterinary clinics and rehabilitation providers, and animal owners seeking rehabilitative services.
Why It Matters
AB 1458 creates a cross-professional regulatory regime that expands service capacity for animal rehabilitation while shifting liability and enforcement responsibilities. Compliance will require new training, written agreements, premises checks, and board notifications — practical and legal changes for both professions.

What This Bill Actually Does
The bill establishes “animal physical therapy” as the practice of physical therapy when applied to animals, and then sets qualifications for which California physical therapists may offer those services. Eligibility hinges on multiple components: an active PT license in good standing, a multi-topic didactic component covering animal assessment, behavior, comparative anatomy, zoonoses, pain recognition and treatment modalities, plus hands-on clinical training under an experienced provider.
The text ties experience requirements to either a block of supervised clinical hours or to prior practice recognized under an existing state regulation, and it explicitly allows qualifying prior experience earned before 2026 to count.
Once qualified, a physical therapist may operate under two discrete pathways. First, the therapist may work under the direct, on-site supervision of a licensed veterinarian at premises registered with the Veterinary Medical Board.
Second, a therapist may accept a veterinarian’s referral provided the therapist maintains a written practice agreement with that veterinarian and gives the animal’s owner a written notice clarifying the therapist’s licensure and limited scope. The bill requires that the practice agreement include coordination and communication protocols and be produced to either licensing board on request.Operational and safety details are spread through the bill: premises used for animal physical therapy must meet local zoning and facility rules; physical therapy aides may assist within existing aide rules; and the statute expressly forbids physical therapists from performing acts that legally constitute veterinary medicine.
The measure also leaves a gap on continuing education, inserting a placeholder rather than a firm hour requirement, which the boards would need to fill by rulemaking or regulation.Enforcement and liability are reallocated: the measure makes violations of the supervision or practice-agreement rules unprofessional conduct subject to discipline under the Physical Therapy Practice Act, requires immediate notification between the PT and Veterinary Medical Boards when either board takes action, forbids disciplined PTs from providing animal therapy, declares a veterinarian’s treatment order non‑liable for therapy performed by the therapist, and places sole liability for delegated therapy tasks on the physical therapist. Collectively, those provisions create explicit lines of regulatory responsibility but also raise practical questions about malpractice coverage, collaborative workflows, and board coordination.
The Five Things You Need to Know
The bill requires at least 100 hours of didactic instruction covering 10 named animal‑related topics and a minimum of 40 hours of supervised clinical training specific to animals.
A physical therapist must complete 125 hours of providing animal physical therapy under direct supervision or have one year of prior animal rehabilitation experience recognized under Title 16 §2038.5; experience before January 1, 2026, counts toward that requirement.
Therapists may provide services either (1) under direct, on‑site supervision by a veterinarian at a Veterinary Medical Board‑registered premise or (2) by referral with an active written practice agreement and written notice to the animal owner; the practice agreement must be producible to either board on request.
The statute makes the physical therapist solely liable for delegated animal physical therapy tasks performed under referral or by aides supervised by the therapist, and it shields a veterinarian from liability for therapy performed pursuant to the veterinarian’s order.
Failure to follow the bill’s supervision, referral, or practice‑agreement requirements (and any implementing regulations) is unprofessional conduct and grounds for discipline; the Veterinary Medical Board’s final discipline against a licensee counts as conclusive evidence of unprofessional conduct under the Physical Therapy Practice Act.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definition: 'animal physical therapy'
This subsection imports the standard statutory definition of physical therapy and applies it to nonhuman patients, making clear that the bill governs physical‑therapy techniques used on animals rather than veterinary medical practices. That definitional boundary is consequential because the statute repeatedly says therapists may not perform acts that constitute veterinary medicine; enforcement will turn on how the two professional scopes are distinguished in regulation and practice.
Education, clinical training, and supervised‑practice thresholds
These paragraphs list the qualifying curriculum topics (assessment, behavior, biomechanics, comparative anatomy, zoonoses, pain recognition, restraint, modalities, etc.), mandate at least 100 hours of didactic instruction plus 40 hours of clinical training, and then set a supervised‑practice floor of 125 hours or one year under an existing regulatory pathway. Practically, those numerics create checkpoint hurdles for PTs and training providers and give licensing boards a concrete basis for approving programs and auditing credentials.
Two practice pathways and the practice‑agreement requirement
This section lays out the dual routes to practice: (1) direct supervision by a veterinarian on a registered premise where a veterinarian has a veterinary‑patient‑client relationship, or (2) practice by referral where the therapist holds an active written practice agreement and provides owner notice. The practice‑agreement content is prescribed at a high level (communication, location, consultation availability, referral protocols) and must be produced to either board on demand, creating document‑management and recordkeeping obligations for therapists and contracting veterinarians.
Delegation, aides, and limits on unlicensed practice
The bill permits physical therapy aides to assist under existing aide rules but otherwise bars unlicensed people from offering animal physical therapy. It also narrows delegation: except for permitted aide activity, the therapist cannot supervise or delegate animal physical therapy under Section 4828.5. Those constraints will shape staffing models and how clinics use nonlicensed assistants in animal rehab services.
Discipline, cross‑reporting, and liability allocation
The statute requires immediate notification between the PT and Veterinary Medical Boards when either imposes discipline and makes Veterinary Medical Board final discipline conclusive proof of unprofessional conduct under the PT law. It bars disciplined PTs from providing animal therapy and assigns sole liability for delegated therapy tasks to the physical therapist while explicitly excluding veterinarian liability for therapy performed by the therapist pursuant to a veterinary order. These are the bill’s primary regulatory carrots and sticks: they create swift information flows between boards and real consequences for noncompliance.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Licensed physical therapists with animal training — Gain a legal pathway to expand services and revenue streams into animal rehabilitation, provided they complete the coursework, clinical hours, and supervised practice the bill requires.
- Animal owners — Access to a broader set of rehabilitation options (e.g., post‑operative therapy, neurologic and orthopedic rehab) where veterinary clinics partner with physical therapists or refer out to qualified therapists.
- Veterinary clinics and large practices — Can build integrated care models by contracting with trained PTs, potentially improving patient outcomes and retaining clients who need long‑term rehab services.
- Educational and continuing‑education providers — New market demand for animal‑specific curricula, clinical placements, and CE offerings if the board approves program standards.
- Physical therapy aides and technical staff — Greater role opportunities within animal rehabilitation teams under the aide rules, subject to supervision limits.
Who Bears the Cost
- Licensed physical therapists — Must pay for additional didactic training, clinical placement, supervised practice hours, liability insurance upgrades, and administrative compliance (board notifications, recordkeeping, practice agreements).
- Veterinarians and veterinary practices — Must take on coordination duties for referrals, potentially sign practice agreements, and ensure premises registration and on‑site supervision if they host therapists; though the bill limits their malpractice exposure, they still bear operational coordination costs.
- Regulatory bodies (PT Board and Veterinary Medical Board) — Face increased workload for credential reviews, cross‑board notifications, complaint handling, and rulemaking to fill gaps (e.g., continuing education hours).
- Insurers and malpractice carriers — May need to reassess underwriting and premium schedules for therapists treating animals and for clinics using hybrid staffing models.
- Small clinics and mobile providers — Must ensure local zoning and premises compliance; smaller operators may find the administrative and training thresholds burdensome.
Key Issues
The Core Tension
The central dilemma is balancing access and specialization against professional boundaries and safety: the bill expands access to animal rehabilitation by letting qualified physical therapists treat animals, but doing so requires carving out clear supervisory, training, and liability rules to prevent unlicensed practice of veterinary medicine — a trade‑off between service availability and maintaining distinct professional responsibility and animal‑health safeguards.
AB 1458 is detailed where it needs to be (training hours, supervised practice, two practice pathways) but contains notable implementation gaps and trade‑offs. Most immediately, the bill leaves the continuing education requirement unspecified, inserting a blank for number of hours; that omission forces the boards to fill an essential credentialing element by regulation and creates uncertainty for providers and CE vendors.
The statute also relies heavily on “practice agreements” whose required elements are described at a high level; without model agreements or clearer minimum standards, agreement content and enforcement likely will vary by practice and could generate disputes about adequate coordination, consultation access, or referral thresholds.
Liability and enforcement design present another tension. The bill’s allocation of sole liability to the physical therapist for delegated animal therapy tasks and the explicit nonliability of veterinarians for therapy provided under their order shifts malpractice exposure toward PTs and their carriers.
That may encourage insurers to raise premiums or carve out coverage, and could discourage collaborative arrangements unless contractual indemnities or insurance arrangements are explicit. Cross‑board discipline and the provision making Veterinary Medical Board discipline conclusive under the PT act simplify enforcement but risk duplicative procedures and raise questions about due process and appeal pathways across boards.
Operationally, the statute confines certain practices to premises registered with the Veterinary Medical Board or to supervised/contracted arrangements, but also contemplates remote settings in practice‑agreement language. How boards reconcile premises registration and local zoning with mobile or in‑home animal therapy remains unclear.
Finally, the bill draws a fine line between animal physical therapy and veterinary medicine; real world cases will quickly test that boundary (for instance, when assessment uncovers conditions requiring veterinary diagnosis), and the statute leaves it to boards and courts to define where the line lies.
