Every state board bans false or misleading advertising. The three biggest boards go further, and the details change what a clinic can put in an ad, on a website or in a reminder.
California gives its Veterinary Medical Board power to discipline a licensee for false or misleading advertising under Business and Professions Code 4883, and the board’s 2026 Practice Act booklet reprints section 651, which applies to every licensed health profession in the state. Under 651 an ad is misleading if it claims professional superiority that cannot be backed by objective scientific evidence, and any advertised price must be exact: no “as low as”, no “and up”, no “lowest prices”. That reaches the wellness plan page and the new-client offer. Emergency claims have their own regulation, 16 CCR 2032.5. A premises that presents itself as an emergency clinic must keep a licensed vet on site during all posted hours, its ads must say so and list the hours, address and phone, and a practice that relies on an on-call vet may not be advertised as an emergency hospital at all. Telehealth is allowed to start a relationship only over live audio and video, never by phone alone or a questionnaire, which matters if you advertise virtual visits.
Texas spells out more in its board rule, 22 TAC 573.30. No prediction of future success, no guarantee that satisfaction or a cure will result, no superiority claim that cannot be verified, and no suggestion that a vet is a specialist unless board certified in a specialty the AVMA recognizes. Rule 573.32 sets the wording for those listings, such as “Board Certified (e.g., Veterinary Radiology)”. Rule 573.37 bars sharing the proceeds of professional services with whoever helped bring the client in, so have your attorney look at any per-client fee to a referral source before it starts.
Florida keeps it to one line in statute 474.214: advertising that is fraudulent, false, deceptive or misleading in form or content is grounds for discipline. The short rule is no softer: it covers form as well as content, so a misleading image or layout counts, not only misleading words.
Read together, the safe copy for any clinic is the same. No “best vet in town”. No cure or guaranteed outcome. “Specialist” only for a board-certified vet in a recognized specialty. Exact prices or none. And “emergency” only when a vet is physically there for every hour you post, which is good practice even where the law does not require it, because the client who drives over at midnight and finds a locked door does not forget it.
