Veterinary practice in Colorado: licensing, complaints, and owner rights

This guide covers general information about Colorado veterinary regulations. It is not legal advice. For specific legal questions, consult an attorney licensed in Colorado.

How veterinary licensing works in Colorado

Veterinarians practicing in Colorado must hold a valid state license issued by the Colorado State Board of Veterinary Medicine, which operates under the Colorado Department of Regulatory Agencies (DORA). A license requires completion of an accredited veterinary degree, passage of national board examinations (NAVLE), and in some cases additional state requirements.

Licenses must be renewed regularly, and licensed vets must meet continuing education requirements to maintain their license. Specialty certifications (board-certified in surgery, internal medicine, dermatology, etc.) are issued by separate national boards, not DORA, and represent advanced training beyond the base veterinary license.

Verifying a vet’s license

The DORA license lookup is a public tool. You can confirm:

• Whether a license is current and active
• Whether any disciplinary actions are on record
• The license type and expiration date

This takes less than two minutes and is worth checking for any provider you are considering for significant or ongoing care.

Your rights as a client

Right	What it means
Access to records	You can request copies of your pet’s complete medical records at any time
Informed consent	You should be told what a procedure involves and its risks before it is performed
Cost discussion	Standard practice (and often required by clinic policy) before non-emergency services
Referral	You can ask for a referral to a specialist at any time; vets are not required to refer but should do so when a case exceeds their expertise
Second opinion	You can seek a second opinion from another licensed vet; your records must be made available to the new provider

These rights are not all statutory — some are standards of professional practice — but they are recognized norms in veterinary care that a professional is expected to uphold.

Filing a complaint

If you believe a veterinarian acted negligently, violated professional standards, or behaved unethically, you can file a complaint with the Colorado State Board of Veterinary Medicine through DORA. The board investigates complaints and can:

• Issue a formal reprimand
• Place conditions or restrictions on a license
• Suspend or revoke a license

The board’s authority covers professional conduct and licensing issues. It does not award financial compensation — that requires civil litigation.

The complaint process typically involves:

1. Submitting a written complaint describing the situation and the specific conduct you believe was improper
2. The board reviewing the complaint for whether it falls within their jurisdiction
3. An investigation, which may include requesting records and interviewing parties
4. A determination and, if warranted, disciplinary action

The board focuses on serious violations: negligence that caused harm, practicing without a license, fraud, or conduct that violates the Colorado Veterinary Practice Act.

What qualifies as veterinary malpractice

Malpractice in veterinary medicine follows similar principles to human medical malpractice: the vet must have deviated from the standard of care (what a competent vet in the same circumstances would do), and that deviation must have caused harm to the animal.

Unhappy outcomes alone do not constitute malpractice — some animals do not respond to treatment or have conditions beyond the vet’s control. A claim requires evidence that the vet did something a competent peer would not have done, or failed to do something they should have. An attorney who handles animal law or general malpractice can evaluate whether a specific situation may warrant a claim.

Pet ownership and liability

Colorado follows the “one bite rule” for dog bites, which has been modified by statute. Dog owners can be held liable for bites in many circumstances. Local ordinances in Denver and surrounding municipalities may impose additional requirements. If your pet has injured someone or been involved in an incident, consult an attorney for your specific situation.
