Can You Transport Animals Across State Lines to Michigan? Rules for Owners and Commercial Shippers

Yes, you can transport animals across state lines to Michigan, and for most dog and cat owners the process is simpler than people expect. Michigan doesn’t require you to obtain an entry permit for either species before you cross the border. But the moment a seller, breeder, shelter, or paid shipper enters the picture, a second layer of federal rules kicks in that a straightforward household move never triggers.

This distinction matters whether you’re driving your own dog (Canis lupus familiaris) to a new home in Grand Rapids or paying a company to fly your cat (Felis catus) in from out of state. Below, you’ll find what Michigan actually requires, when the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service gets involved, and what to check before you hire anyone to move an animal for you.

Short Answer: Yes — With Conditions for Dogs and Cats

For personal pet owners, the core requirement is a certificate of veterinary inspection, not a state-issued permit. Michigan’s Department of Agriculture and Rural Development confirms that Michigan does not issue entry permits for dogs to be imported, so no permit number needs to appear on the interstate certificate of veterinary inspection. The same holds for cats: Michigan does not issue entry permits for cats, so no permit number is required to be written on the interstate certificate of veterinary inspection.

Age matters for rabies proof. Dogs 12 weeks or older must be currently vaccinated against rabies, and dogs younger than 12 weeks from a rabies-quarantined area aren’t allowed entry. Cats follow a similar pattern — cats 12 weeks of age or older must also be currently vaccinated against rabies before they cross into the state.

Pro Tip: Ask your veterinarian to write the vaccination date, expiration date, and vaccine type directly on the certificate of veterinary inspection. Missing dates are one of the most common reasons a CVI gets rejected at inspection.

What This Covers (vs. “Traveling With Pets to [State]”)

General “traveling with pets” guides focus on carriers, road trip breaks, and airline cabin rules for people vacationing with an animal. This article covers something different: the legal and regulatory side of actually moving or shipping an animal into Michigan, whether that’s a personal relocation, a rescue transport, or a commercial sale.

If you want the consumer-facing version — vaccination checklists, breed-specific notes, and step-by-step packing advice for a personal move — the companion piece on pet import laws in Michigan covers that ground in more depth. What follows here digs into where federal oversight starts, what paperwork a commercial shipper needs that a personal mover doesn’t, and how to vet the people you’re paying to move an animal for you.

Personal Owner Move vs. Commercial Pet Transport

Michigan’s paperwork requirements don’t change much between a personal move and a commercial shipment — but the federal rules layered on top do. The Animal Welfare Act draws a sharp line based on custody, not distance traveled.

Factor	Personal Owner Move	Commercial Pet Transport
Who has custody	You, the entire trip	A paid third party (driver, airline, broker)
Federal AWA oversight	Not regulated	Regulated if for-hire
Michigan CVI requirement	Yes, for dogs and cats	Yes, plus possible sale-related overlays
USDA registration needed	No	Often yes (Class T or intermediate handler)

The federal side of this comes straight from APHIS’s own guidance: transportation of pets that remain in the custody of their owners is not regulated under the AWA — for example, pets that travel in the cabin of an aircraft with their owner, or that ride along with their owner in a hired taxi. Hand your animal off to someone else for the trip, though, and the calculus changes.

Destination Entry Rules (brief; cross-link Traveling series)

Michigan’s actual entry law is short by design. Beyond the CVI and age-based rabies proof already covered, the state adds specific overlays once a sale, exchange, or transfer is involved — details covered in the next section. State statute, specifically MCL 287.335a, governs what pet shops, breeding kennels, and shelters must do before an animal crosses the border for resale.

Important Note: Michigan’s administrative code still contains an older rule (R 285.112.1) allowing local quarantine of dogs imported from within 50 miles of a recent rabies exposure, with quarantine at destination for a period of not less than 60 days at the state’s discretion. MDARD’s current published guidance for routine imports doesn’t reference this provision directly, so if your dog is coming from an area with a recent rabies case, confirm with your accredited veterinarian or MDARD whether it could apply.

Documents Shippers Need: Rabies, CVI, Sale/Ownership-Change Overlays

Every dog or cat entering Michigan needs the same baseline document: a signed interstate CVI. Beyond that baseline, three overlays commonly apply to shippers, breeders, and anyone moving an animal that’s changing hands.

• CVI signed by an accredited vet: The certificate must be filled out and signed by a USDA-accredited veterinarian licensed in the animal’s state of origin, listing vaccination dates and any parasite treatment given.
• Rabies proof tied to age: Required once the animal hits 12 weeks, per the thresholds above; Michigan’s rabies guidance for imported dogs sets the vaccination requirement at three months of age and over.
• Sale or ownership-change overlay: If the animal is being sold, exchanged, or transferred through a pet shop, breeding kennel, or shelter, Michigan law adds extra vaccine requirements. If indicated, the animal must be treated for external and internal parasites so it isn’t capable of spreading them to another animal at the time of import, and non-rabies vaccinations for cats must be administered at least 7 days before the cat’s entry into the state.

These overlays exist because a commercial sale introduces risk that a personal move doesn’t — a pet shop or shelter is bringing in animals from unknown backgrounds, often in volume, rather than one owner moving one known pet.

When USDA APHIS Does Regulate (AWA commercial carriers / intermediate handlers)

Federal oversight turns on one question: is someone taking custody of the animal “for hire”? APHIS answers this directly in its own compliance guidance.

Commerce covered under the Animal Welfare Act includes the inter- and intrastate transport of animals for sale, for research, as pets, or for exhibition. More specifically, any airline, motor carrier, rail carrier, shipping line, or other business taking custody of AWA-regulated animals and transporting them “for hire” is regulated — a category that includes boarding kennels or hired drivers who take responsibility for shipping animals without the owner physically present.

Two registration categories cover most of the businesses you’ll encounter:

• Intermediate handlers: Anyone taking custody of regulated animals in connection with transporting them on public carriers must register as an intermediate handler — a requirement covering boarding kennels that arrange shipping, freight forwarders, and freight handlers.
• Class T carriers: For pet transport companies, the relevant AWA category is Class T — “T” for transporter. There’s a small-scale carve-out, though: the AWA exempts transporters who handle four or fewer animals in a year, which is why an occasional favor between neighbors doesn’t trigger federal registration but a running pet-shipping business does.

Hiring a Pet Shipper, Relocator, or Broker

If you’re paying someone to move your animal instead of doing it yourself, a little vetting up front saves headaches later. Start by asking whether the company operates as a registered Class T carrier — USDA Class T carriers transport pets for hire using private vehicles, and legitimate operators should be able to produce a registration number on request.

Ask these questions before you sign a contract:

1. What is your USDA registration number, and are you registered as a carrier, an intermediate handler, or both?
2. Do you carry insurance that covers the animal during transport?
3. What’s your emergency contingency plan if a vehicle breaks down or a flight is delayed?
4. Will you provide the CVI, or do you need me to arrange the vet visit before pickup?
5. How do you handle Michigan’s rabies-age thresholds if the animal is a puppy or kitten near the 12-week cutoff?

A boarding kennel that quietly arranges its own shipping without disclosing that role is exactly the kind of business the intermediate-handler rule was written to catch — so if a company seems vague about its registration status, treat that as a red flag rather than an oversight.

Airline Cargo vs. Ground Transport

Both modes fall under AWA oversight once money changes hands for the transport, but the practical experience differs quite a bit. Airlines fall squarely into the carrier definition: any airline… taking custody of AWA-regulated animals and transporting them “for hire” is regulated, which means cargo holds are subject to federal transportation standards covering temperature, ventilation, and handling.

Ground transport companies register the same way, typically as Class T carriers, but the door-to-door nature of ground shipping means the animal usually stays with the same handler for the entire trip rather than passing between an intermediate handler, an airline crew, and a receiving party at the destination airport. For a state like Michigan with no entry permit requirement, ground transport often simplifies the paperwork handoff since there’s one CVI and one continuous chain of custody rather than several.

Pro Tip: If you’re comparing quotes, ask each company whether your pet will change hands mid-route. More handoffs mean more intermediate handlers involved — and more parties who need to be properly registered under the AWA.

Hawaii Special Case for Shippers

Michigan’s lack of an entry permit makes it one of the easier mainland destinations for shippers to route through — which makes Hawaii’s rules a useful contrast if your route or your client’s move involves a multi-leg trip. Hawaii runs the strictest pet-import system in the country, and it applies no matter how the animal got there.

Because Hawai’i is rabies free, resident pets aren’t required to be vaccinated for rabies — but incoming animals face the opposite burden. Current law requires dogs, cats, and carnivores to complete either the 120-day quarantine or the 5-Day-Or-Less program before release, and the 120-day quarantine program costs $1,080 per pet. As Hawaii’s Animal Quarantine Branch put it, “All dogs and cats, regardless of age…or purpose, must comply with Hawai’i’s dog and cat import requirements,” a rule that even covers short-term visitors.

Important Note: A layover or connecting flight through Hawaii doesn’t exempt an animal from these rules if Hawaii is the actual destination. Any shipper routing a pet there needs to plan the FAVN blood test and waiting periods months in advance, not the week before travel.

The strict quarantine exists partly to protect the state’s isolated ecosystem — Hawaii is home to a number of endangered species found nowhere else that would be vulnerable if rabies or other diseases became established there.

One-Line Note: Livestock Is a Different Regime

Everything above applies to dogs and cats moved as pets — livestock operates under an entirely separate USDA and state veterinarian framework built around herd health certificates, brand inspections, and species-specific testing rather than CVIs and rabies age thresholds. Cattle, in particular, run on their own import rules; the process for moving cattle across state lines to Wyoming or shipping cattle to Wisconsin looks nothing like moving a family dog, partly because ruminants like cattle are animals with multiple stomachs subject to disease-testing protocols that pets simply don’t face.

Pre-Ship Checklist

Whether you’re moving your own pet or coordinating a commercial shipment into Michigan, working through these steps in order keeps you from discovering a missing document at the border.

1. Schedule the vet exam early. Book the CVI appointment with a USDA-accredited veterinarian well before your travel date — some vets need lead time to fit in an export exam.
2. Confirm the rabies-age threshold. If your dog or cat is close to 12 weeks old, verify whether the vaccination has been given and documented before you finalize travel dates.
3. Check for sale/ownership-change overlays. If the animal is being sold, adopted out, or transferred through a shelter or breeder, confirm the additional vaccine and parasite-treatment requirements apply.
4. Verify shipper registration. If you’re hiring a transporter, ask for their USDA registration number and confirm whether they’re a Class T carrier, an intermediate handler, or both.
5. Match the CVI window to your travel date. Confirm with your vet how close to departure the certificate needs to be signed.
6. Prepare the crate to standard. Airline and ground carriers alike expect crates that meet AWA enclosure standards — check requirements before pickup day.
7. Check any additional-state rules on the route. If the trip passes through or terminates in a state with stricter rules — Hawaii being the extreme example — plan for those requirements months ahead.

Where to Verify Current Rules

Import requirements get updated, so confirm details directly with primary sources before you travel rather than relying on secondhand summaries — including this one. For Michigan-specific requirements, MDARD’s dog import page and cat import page are the authoritative references and get updated when state rules change.

For federal oversight questions — whether a shipper needs Class T registration, or whether a boarding kennel arranging transport counts as an intermediate handler — APHIS’s Pet Travel page is the government’s own clearinghouse for those rules. If Hawaii is anywhere in the route, go straight to the state’s Animal Quarantine Station rather than a third-party summary, since the timing windows for the FAVN test and waiting periods are strict and unforgiving.

Educational Note: This article summarizes publicly available state and federal guidance as of publication and is not legal advice. Import rules can change, and specific circumstances — breed restrictions, connecting states, or animals other than dogs and cats — may call for direct confirmation with MDARD or an accredited veterinarian before you travel.
