If you share your life with a pet, you have probably felt the squeeze at the vet’s office: appointments booked out for weeks, a waiting room that never empties, and a staff that looks quietly exhausted. That strain is exactly what a Colorado ballot measure set out to address, and in November 2024, voters said yes to a genuinely novel answer.
On November 5, 2024, Coloradans narrowly passed Proposition 129, a measure that establishes a new profession sitting between the veterinarian and the veterinary technician: the veterinary professional associate, or VPA. The vote makes Colorado the first state in the country to create such a role, and it could reshape who is allowed to care for your animal.
What a VPA actually is
Think of the way you sometimes see a physician associate instead of a doctor at a human clinic. The VPA is built on that same logic, with one striking difference: a VPA will be permitted to perform certain surgeries.
Under the new law, a VPA holds a master’s degree in veterinary clinical care and has to register as a VPA with Colorado’s veterinary licensing board. That credential clears them to take on duties Colorado currently reserves for fully licensed veterinarians, including examining patients, reaching a diagnosis, starting treatment, and handling routine procedures such as spays and neuters. Every bit of that work has to happen under a licensed veterinarian’s supervision.
The pitch is straightforward. Adding a trained mid-level clinician is meant to shorten wait times, stretch a thin workforce further, and widen access to care, especially in rural stretches of the state where the nearest clinic can be an hour away. It also hands veterinary technicians something the field has long lacked: a rung to climb toward higher pay and more responsibility.
How the three roles compare
It helps to line the jobs up side by side.
A veterinarian completes an undergraduate degree, then four years of veterinary school to earn a doctorate in veterinary medicine. In Colorado, only a veterinarian can currently diagnose, begin treatment, write prescriptions, or operate.
A certified veterinary technician earns a two-year associate degree. Techs are essential in clinics and shelters, but the law does not let them make a diagnosis, start a course of treatment, or operate. Those who hold a veterinary technician specialist credential carry extra training on top of that.
A veterinary professional associate, the new tier, starts with a four-year bachelor’s degree in a related field, then completes a master’s program of specialized clinical training. Graduates are trained to catch abnormal findings during exams and lab work and to diagnose and treat routine medical and surgical cases, spay and neuter surgeries among them, always with a licensed vet overseeing the work.
Why Colorado went looking for a fix
The state is short on veterinarians, and it is not alone. Reporting from CBS Colorado put the imbalance in blunt terms: roughly 3,800 veterinarians serve about 2.5 million dogs and cats, a figure that does not even count horses and livestock. A survey of Colorado veterinarians run by Colorado State University’s Animal-Human Policy Center found that around 70 percent were turning animals away because they simply could not keep up.
Backers of Proposition 129, a coalition that included the ASPCA, the Dumb Friends League, and several animal-welfare and industry groups, argued that VPAs could relieve that pressure by growing the workforce and offering more affordable routine care.
“The pets I worry about most are the ones whose families keep putting off care because they can’t get in the door or can’t afford the visit,” says Dr. Amara Solis, a veterinarian on The Pet Times advisory team. “If a well-supervised mid-level clinician gets a wobbly puppy seen this week instead of next month, that is a real win. The whole thing rides on the supervision and the training being genuine, not decorative.”
The case against it
Plenty of professionals are uneasy. The American Veterinary Medical Association opposed the measure, warning that a VPA would not carry anywhere near a veterinarian’s depth of training, which matters a great deal when the job description includes cutting into an animal and prescribing drugs. The AVMA criticized the proposed CSU curriculum for requiring roughly half the credit hours of a typical veterinary doctorate and for leaning heavily on online coursework, and it noted there was no nationally recognized accreditation for such a degree and no national competency exam to sit for.
Critics also raised an equity worry: that lower-income pet owners could end up funneled toward a lower tier of care while wealthier clients still see full veterinarians. Supporters flipped that argument around, telling CPR News that expanding the roster of who can treat animals actually widens the options for families who currently have none, and eases the load on overwhelmed shelters.
There was an alternative on the table, too. Opponents pointed out that Colorado had already broadened what veterinary technicians can do earlier in 2024 through House Bill 24-1047, the Veterinary Technician Scope of Practice bill, which lets veterinary technician specialists assist in surgery, perform dental procedures, and manage some minor conditions under a veterinarian’s direct supervision. Their argument: build on the trained people already in the room rather than invent a new job.
What’s new since the vote
The measure did not just pass and vanish into paperwork. The State Board of Veterinary Medicine has since worked through its initial rulemaking, and the framework establishing the VPA role took effect on January 1, 2026. Colorado State University’s College of Veterinary Medicine and Biomedical Sciences developed the master’s program designed to train these clinicians, meaning the first cohorts are moving through the pipeline rather than the idea staying theoretical.
For pet parents, the practical payoff will be gradual. You will not walk into a clinic tomorrow and meet a VPA on every shift; it takes time to train and register a new class of professional. But Colorado is now the test case the rest of the country is watching. If the model reduces wait times without compromising care, expect other states wrestling with their own shortages to draft copycat measures. If it stumbles, that will shape the debate just as loudly.
The bottom line
Proposition 129 is less about a job title than about a bet on how veterinary care gets delivered for the next generation of pets. Colorado decided the shortage was serious enough to try something no other state had. Whether the VPA turns out to be a smart pressure valve or a shortcut with hidden costs will come down to how rigorously the training and supervision hold up in practice.
