Pet Import Laws in Colorado: What Every Pet Owner Needs to Know Before Moving

Moving to Colorado with a pet takes more than packing a travel crate and hitting the road. The state enforces specific import requirements for dogs, cats, birds, exotic animals, and even pocket pets — and arriving without the right paperwork can mean quarantine, fines, or being turned away at the border.

Whether you’re relocating from another U.S. state or arriving from another country, this guide walks you through exactly what Colorado requires, who issues the documents you need, and who to contact before you arrive with your animal.

What Documents Do You Need to Bring a Pet Into Colorado

The cornerstone document for importing nearly any pet into Colorado is the Certificate of Veterinary Inspection, commonly called a CVI or health certificate. A CVI is the officially completed form, whether written or electronically generated, approved by the State Veterinarian of the state of origin and issued by a licensed, accredited veterinarian. Think of it as your pet’s travel passport — without it, entry into Colorado is not guaranteed.

There are a few critical rules about timing and format that catch many pet owners off guard:

• The CVI must be issued by an accredited veterinarian within 30 days prior to entry and must state that the dog or cat is free from exposure to rabies.
• The VS Form 7001 is NOT accepted as a CVI for interstate travel to Colorado.
• PACFA-licensed facilities are required to have a CVI within 10 days prior to entry — a tighter window than the standard 30-day rule for private owners.

Beyond the CVI, rabies vaccination records are required for dogs, cats, and ferrets over three months of age. Cats and dogs over 3 months of age must have proof of an up-to-date rabies vaccination, and the vaccination date, vaccine manufacturer, and serial number must be listed on the CVI.

Important Note: Animals entering Colorado without a valid health certificate or required permit may be held in quarantine at the owner’s risk and expense until released by an authorized representative of the State Veterinarian. Noncompliance can also result in civil fines.

For certain exotic species, you will also need a separate entry permit issued before your animal crosses the state line. The type of permit depends on the species, so contacting the Colorado Department of Agriculture (CDA) or Colorado Parks and Wildlife (CPW) ahead of time is essential.

Dog Import Requirements in Colorado

Dogs are among the most commonly imported pets in Colorado, and the state’s requirements are straightforward but non-negotiable. Dogs and cats imported into Colorado from another U.S. state need a Certificate of Veterinary Inspection (CVI) issued by an accredited veterinarian within 30 days prior to entry, stating that the dog is free from exposure to rabies.

Rabies vaccination is a firm requirement for dogs old enough to receive it. All cats and dogs over 3 months of age are to be vaccinated for rabies prior to entry into Colorado and must be current on their vaccination. Make sure your vet lists the vaccination date, the vaccine manufacturer’s name, and the serial number directly on the CVI — a separate vaccination card alone is not sufficient.

Pro Tip: Schedule your vet appointment no earlier than 30 days before your move date. A CVI issued too early will be expired by the time you cross into Colorado, requiring a second appointment and additional cost.

If you are moving your dog into a PACFA-licensed facility — such as a kennel, rescue, or shelter — the rules are stricter. Dogs imported into PACFA-licensed facilities are required to have a CVI within 10 days of entry. This shorter window exists to protect the health of multiple animals housed together.

Once you’re settled in Colorado, it’s worth familiarizing yourself with the state’s ongoing rules for dog owners. Dog leash laws in Colorado vary by county and municipality, so knowing the rules in your new area matters just as much as the import paperwork.

Cat Import Requirements in Colorado

The requirements for importing cats into Colorado mirror those for dogs in most respects. You need a valid CVI issued within 30 days of entry, and cats over three months of age must be current on their rabies vaccination with full details recorded on the health certificate.

One distinction worth noting involves local rabies authority. The Colorado Revised Statutes give the local or county board of health the authority to determine the requirements for rabies vaccination, meaning some counties may have additional or stricter rules beyond the state baseline. Check with the animal control office in the specific county you’re moving to, not just the state-level requirements.

If your cat temporarily left Colorado and is returning, the re-entry rules depend on how long you were gone. If return to Colorado is within 30 days from departure, no CVI is required for return. If return to Colorado is greater than 30 days from departure, a CVI will be required to return to Colorado.

Key Insight: Colorado law designates dogs and cats adopted from Colorado animal shelters and rescues as the official state pets. If you’re adopting locally rather than importing, the shelter handles the paperwork — but if you’re bringing a cat from out of state, the CVI and vaccination requirements apply regardless of whether the animal is a rescue.

Cats traveling to Colorado from another country face additional requirements, which are covered in the international section below. European Pet Passports are accepted under certain conditions as a substitute for a CVI, but only when specific certification conditions are met.

Bird and Exotic Pet Import Requirements in Colorado

Importing birds and exotic pets into Colorado involves more layers of oversight than bringing in a dog or cat. Multiple agencies — including the Colorado Department of Agriculture, Colorado Parks and Wildlife, and federal bodies — may all have jurisdiction over your animal.

Pet Birds

All pet birds must meet the requirements of U.S. Fish and Wildlife Services, USDA, and Colorado Parks and Wildlife prior to entry. Pet birds must be an approved species by Colorado Parks and Wildlife, U.S. Customs and Border Protection, and U.S. Fish and Wildlife Services. This means you cannot simply assume your parrot, cockatiel, or finch qualifies — species approval must be confirmed before you travel.

A CVI issued by an accredited veterinarian within 30 days of entry is also required for birds. All game birds such as pheasant and chukar must meet poultry requirements, and a Certificate of Veterinary Inspection issued by an accredited veterinarian within 30 days is required.

If you keep backyard poultry in addition to companion birds, Colorado has its own set of local rules to navigate. The backyard chicken laws in Colorado and rooster laws in Colorado outline what’s permitted at the municipal and county level.

Ferrets

Ferrets over 3 months of age must have proof of an up-to-date rabies vaccination, with the vaccination date, vaccine manufacturer, and serial number listed on the CVI. A CVI issued by an accredited veterinarian within 30 days prior to entry is required. Notably, there is no rabies vaccination requirement to import ferrets into Colorado from another state — but the CVI is still mandatory.

Pocket Pets, Reptiles, and Amphibians

This category includes other pocket pets such as gerbils, guinea pigs, hamsters, mice, amphibians, and reptiles. This does not include exotic animals, which must meet separate requirements. Approval from Colorado Parks and Wildlife may be required prior to entry depending on the species.

Colorado Parks and Wildlife updated its herpetofauna regulations in 2026, which affects how reptiles are classified and what documentation is required. A person may possess or transport a species listed in Appendix B only if the person has documentation in the form of a receipt or bill of sale, a donation certificate, a Certificate of Veterinary Inspection used for importation, or documentation that the animal was propagated from lawfully possessed parents. If you’re bringing a reptile into Colorado, verify your species’ classification under the updated 2026 CPW herpetofauna regulations before you travel.

For a broader look at what exotic animals are and aren’t permitted at the federal level, the United States laws on exotic pets provide useful context on federal restrictions that apply on top of Colorado’s state rules. You may also want to review hedgehog ownership laws in Colorado if you’re bringing one of these increasingly popular pets to the state.

Common Mistake: Assuming that a species legal in your home state is automatically legal in Colorado. Colorado Parks and Wildlife maintains its own approved and prohibited species lists. Always confirm your specific animal’s status with CPW at (303) 297-1192 before your move date.

Exotic Animals Requiring Permits

Colorado’s Pet Animal Care and Facilities Act (PACFA) prohibits the importation, possession, sale, and transfer of apes by exotic pet owners and animal dealers. More broadly, a permit is required prior to entry for certain exotic species, obtained by calling (303) 869-9130. If your animal falls into a regulated exotic category, apply for this permit well in advance — it must be in hand before you cross the state line.

Requirements for Pets Coming From Outside the United States

Bringing a pet into Colorado from another country means satisfying both federal import requirements and Colorado’s state-level rules. In most cases, the state requirements are the same as for interstate travel, but international arrivals carry additional layers of documentation.

Dogs and Cats From Other Countries

Importing dogs and cats from other countries into Colorado requires a Certificate of Veterinary Inspection issued by an official veterinarian within 30 days prior to entry. European Pet Passports may be used in place of a CVI if there is certification on the passport by an official veterinarian that the pet has been examined within 30 days of arrival in Colorado and found to be free of contagious or communicable disease.

Rabies vaccination requirements apply to both dogs and cats arriving internationally. Dogs over 3 months of age must have proof of an up-to-date rabies vaccination, and the vaccination date, vaccine manufacturer, and serial number must be listed on the CVI or European Pet Passport. The same standard applies to cats over 3 months of age.

Dogs arriving from another country also require an ISO-compatible microchip. An ISO-compatible microchip is required for dogs imported internationally into Colorado. If your dog’s microchip was implanted in another country, confirm it meets ISO standard 11784/11785 before departure — not all chips used outside the U.S. are compatible with American scanners.

Federal Requirements That Apply First

The CDC issues regulations to control the entry of dogs into the United States from other countries, and these rules apply to all dogs, including puppies, service animals, and dogs that left the United States and are returning. You must clear CDC requirements at the federal port of entry before Colorado’s state rules even come into play.

Cats are subject to inspection at ports of entry and may be denied entry into the United States if they have evidence of a zoonotic disease. If a cat appears to be ill, further examination by a licensed veterinarian at the owner’s expense might be required before the cat is allowed to enter.

Countries Not Listed in Colorado’s System

If you are importing animals into Colorado from a country not listed in the state’s system, you may need to contact both the USDA and the Colorado Department of Agriculture to ensure you meet all federal and state requirements. For federal import requirements, call your local USDA Area Office. For Colorado-specific requirements, contact the CDA at 303-869-9130 or animalhealth@state.co.us.

Ferrets From Other Countries

A CVI issued by an official veterinarian within 30 days prior to entry is required for internationally imported ferrets. Ferrets over 3 months of age must have proof of an up-to-date rabies vaccination, and the vaccination date, vaccine manufacturer, and serial number must be listed on the CVI.

How to Find a Federally Accredited Vet Before You Move

Not every licensed veterinarian can issue the documents Colorado requires. For interstate travel, you need a USDA-accredited vet. For international travel, the requirements are even more specific.

A USDA-accredited veterinarian has completed formal training from the National Veterinary Accreditation Program (NVAP) in the state or states where they are licensed to practice medicine. Accreditation is state-specific and voluntary — not all veterinarians are accredited. This means your regular vet may not qualify, even if they’ve been treating your pet for years.

Here’s how to locate one before your move:

1. Use the NVAP self-search tool. Use the NVAP self-search tool for finding accredited veterinarians in your area. This tool is available through the USDA APHIS website at vsapps.aphis.usda.gov and lets you search by state and zip code.
2. Call local practices directly. Call and ask your local veterinarian if they or another veterinarian in their practice is accredited, or if they know of someone who is. Contact other local veterinary practices to ask if they have an accredited veterinarian on staff.
3. Confirm accreditation in the right state. Make sure your USDA-accredited veterinarian is accredited in the state where you’re seeing them. APHIS cannot endorse your health certificate if your veterinarian is not accredited in the state where they’re practicing medicine.
4. Check category for birds and livestock. If you’re traveling with birds or livestock, make sure your veterinarian has a Category II accreditation status for completion of international health certificates for birds or livestock.

Pro Tip: Book your accredited vet appointment as early as possible — ideally 6 to 8 weeks before your move. Accredited vets can be in short supply in some areas, and you need the CVI issued within 30 days of entry, not 30 days before you start looking for an appointment.

If you’re moving from a state with its own dog laws, it’s worth reviewing what regulations applied to you before — and what changes in Colorado. Resources like California dog leash laws, Arizona dog leash laws, and Florida dog leash laws can help you understand what you’re leaving behind and what to expect in your new state.

Who to Contact in Colorado Before You Arrive With a Pet

Reaching out to the right agencies before your move date can prevent costly delays, quarantine situations, or denied entry. Colorado has multiple points of contact depending on your animal type and origin country.

You can also view the State Veterinarian’s Office Contact List to acquire more information on each state’s animal transport regulations, or visit the USDA website for additional details and international animal transport regulations.

If you’re moving from another state and want to compare how Colorado’s rules stack up, you might find it useful to review pet and animal laws in states like Ohio, Tennessee, or Pennsylvania to see what you were working with before.

Before You Arrive: A Quick Action Checklist

• Confirm your pet’s species is approved for entry into Colorado (especially for birds, reptiles, and exotic animals)
• Locate a USDA-accredited veterinarian in your current state using the NVAP search tool
• Schedule your CVI appointment no more than 30 days before your move date (10 days if moving into a PACFA-licensed facility)
• Ensure rabies vaccination records include the date, manufacturer, and serial number
• Apply for any required entry permits from CDA or CPW before your travel date
• For international arrivals, confirm CDC requirements are met at the federal port of entry first
• Contact CDA at (303) 869-9130 if your country of origin is not listed in Colorado’s import system

Colorado’s pet import rules exist to protect both resident animals and the state’s broader wildlife ecosystem. Colorado’s roadkill laws and rooster crowing ordinances are just two examples of how seriously the state takes animal-related regulations. Getting your paperwork right before you arrive means you can focus on settling in — rather than sorting out compliance issues at the border.
