Pet Transport to and from Michigan: Rules, Routes, and Real Costs

Michigan is one of the states where the paperwork answer is simple and the geography answer is not. Plenty of states let an owner drive their own pet across the line with nothing in hand. Michigan is not one of them, and that catches people out. The harder part is the map. Michigan is two peninsulas separated by water, with an Upper Peninsula that most national ground carriers treat as a spur off Wisconsin rather than part of Michigan at all. Add a border crossing at Detroit and a winter that shuts down air cargo more reliably than a southern summer does, and a Michigan move needs planning that a Georgia move does not.

What Michigan actually requires when a pet arrives

Michigan sits in the strictest of the four categories we track across states. There is no owner-accompanied exemption written into the entry rule, and no distinction between a pet riding in the family car and one riding in a commercial van. According to the Michigan Department of Agriculture and Rural Development, dogs entering Michigan must have an official interstate certificate of veterinary inspection completed by a USDA accredited veterinarian in the state of origin, and must be currently vaccinated against rabies if they are 12 weeks of age or older. Dogs under 12 weeks of age coming from a rabies quarantined area are not permitted entry at all.

Cats are covered too, and this is where people assume wrongly. A common belief is that cats travel on lighter paperwork than dogs. In Michigan they do not. MDARD states that cats must also have an official interstate certificate of veterinary inspection from an accredited veterinarian in the state of origin, and it notes that Michigan does not issue entry permits for imported cats, so no permit number needs to appear on the certificate. That last detail saves a phone call, because vets in other states sometimes stall on a Michigan cat certificate waiting for a permit number that does not exist.

Practically, that means every Michigan-bound animal needs a vet appointment before departure, not after arrival. A certificate is generally treated as valid for 30 days from the examination date, which is more generous than the 10-day window several states apply, but it is still a hard clock. If your move slips by three weeks, check the date before the driver loads. Our guide to the pet health certificate for travel covers what the document contains and who can legally sign it. The one shortcut worth knowing: book the vet appointment for the same week the transporter has quoted, not the moment you decide to move.

Michigan's New World Screwworm entry requirements

Michigan added a second layer in mid-2026 that most competing pages have not caught up with. MDARD implemented new domestic animal entry requirements to protect against New World Screwworm, effective June 17, 2026. The rules apply to certain warm-blooded domestic animals, dogs included, arriving from areas the USDA has designated as an NWS Infested Zone or an Adjacent Surveillance Zone.

Read that scope carefully, because it is narrower than the headlines suggested. This is not a blanket rule on every animal entering Michigan. It applies to animals originating in or travelling from designated areas, which at present means specific counties in southwest Texas and New Mexico. If your pet is moving from Ohio or Florida or Oregon, none of it touches you.

If it does touch you, the requirements are real. Covered animals need an interstate certificate of veterinary inspection carrying an explicit statement that the animals were inspected and found free of evidence of NWS infestation, plus an MDARD approval permit, plus documentation of wound care and preventative treatment. Certificates go to MDARD before transport rather than at the door. Any open wounds must be noted on the certificate, and if a shipment arrives with animals whose wounds were flagged, their current status has to be reported back to MDARD within 24 hours of arrival. Animals from a premises under active infestation quarantine are barred from entering Michigan entirely until that quarantine is released.

The designated zones move as detections are confirmed and cleared. Do not treat any county list you read anywhere, including here, as permanent. If your route starts anywhere in the southwest, check the MDARD screwworm page in the week you actually travel, not the month you booked.

The Upper Peninsula is a separate logistics region

This is the single biggest cost driver in Michigan and the one almost no national quote form accounts for. The Upper Peninsula is not simply the far end of Michigan. It is reachable from the Lower Peninsula only by the Mackinac Bridge, and from anywhere else by driving through Wisconsin. Marquette, the largest UP city, is roughly 450 road miles from Detroit but only about 170 from Green Bay.

National ground operators build routes on interstate spines. In Michigan that means I-94 and I-96 across the south, I-75 up the middle, and the Chicago to Detroit run that ties into everything east. The UP touches none of that. A driver going to Marquette is leaving a productive corridor for a long out-and-back with very little chance of picking up a second animal to share the cost, which is exactly how multi-pet ground routes stay affordable.

The result is a genuine premium, often several hundred dollars above what the raw mileage suggests, and sometimes a refusal. The practical move is to ask any operator quoting a UP pickup or delivery one specific question: are you running this as a spur off a Michigan route or off a Wisconsin route? A carrier that already runs Minneapolis to Chicago through Green Bay can reach Marquette far more cheaply than one basing out of Detroit. Same destination, very different economics. Our overview of how ground pet transport routing works explains why shared routes price the way they do.

Sault Ste. Marie, Escanaba and Iron Mountain sit in the same category. Traverse City is easier, since it is on the Lower Peninsula, but it is still 255 miles north of Detroit and off the main east-west spine, so it prices closer to a UP run than a Lansing run.

The Mackinac Bridge, wind, and lake-effect snow

If your route crosses the Straits of Mackinac, the bridge itself is a scheduling variable. The Mackinac Bridge Authority publishes the thresholds, and they matter because a pet transport van is precisely the vehicle class restricted first. The Authority states that high-profile vehicles must be escorted across at sustained winds of 35 to 50 mph, the bridge closes to high-profile vehicles entirely at 50 to 65 mph, and closes to all traffic above 65 mph. Those figures are sustained winds, not gusts.

A tall cargo van carrying crates counts as high-profile. So a UP delivery can be held for hours by weather that a passenger car would drive straight through. Build a buffer day into any November through March crossing and do not schedule a same-day vet appointment on the far side.

Lake-effect snow is the other constraint, and it is unevenly distributed in a way that surprises out-of-state drivers. Cold air moving east across Lake Michigan dumps heavily on the western side of the Lower Peninsula, which is why Grand Rapids, Muskegon and the US-31 corridor can be buried while Detroit stays clear on the same day. The same effect off Lake Superior hits the western UP hardest. An operator quoting a Chicago to Grand Rapids leg in January is quoting through that belt, not around it.

Cold embargoes matter more here than heat embargoes

Most pet transport writing treats temperature embargoes as a summer problem, because most of it is written for the south. In Michigan the binding constraint runs the other way, and it removes air cargo as an option for a large part of the year.

American Airlines Cargo, as one representative example, states that it transports warm-blooded animals when ground temperatures are between 45 and 85 degrees Fahrenheit at origin, connection and destination. Below 45F the carrier requires an acclimation letter signed by a licensed veterinarian, and below 20F it will not carry the animal at all. Other carriers set similar floors.

Now apply that to Michigan. Detroit, Grand Rapids, Lansing and Traverse City all spend most of December through February below 45F, and Marquette spends longer than that. The origin, connection and destination all have to clear the threshold, so a January flight out of Detroit connecting through Chicago fails on two counts before the destination is even considered. This is why so many Michigan winter moves end up on the road regardless of distance, and why cross-country ground transport is worth pricing early rather than as a fallback after a flight is refused at the counter.

The flip side is that Michigan summers rarely trip heat embargoes, so June through September is the easy air window if flying matters to you. That is also peak ground season, when rates run highest.

Detroit sits on an international border

Detroit is the only major US metro where the country to the south is Canada, and Michigan carries four crossings that matter for animal movement: the Ambassador Bridge and the Detroit Windsor Tunnel at Detroit, the Gordie Howe International Bridge, and the Blue Water Bridge at Port Huron. Any of them turns a domestic move into an international one, with a different rulebook.

For a personal pet heading north, the core document is a rabies vaccination certificate in English or French, signed by a licensed veterinarian and identifying the animal and the vaccine. USDA APHIS maintains the current checklist for pet travel from the United States to Canada, and it is the page to read rather than a transporter's summary, because commercial movement and animals under three months follow different paths than an owner-accompanied adult dog.

There is a specifically Michigan trap here worth naming. Detroit to Buffalo is meaningfully shorter through Ontario than around the bottom of Lake Erie. Drivers know this and some will route that way by default. For a pet in the vehicle, that convenience converts one domestic trip into two international crossings, each requiring the animal to satisfy entry rules in both directions. Ask any operator quoting a Michigan to New York or New England run to confirm the routing in writing. If the answer is through Canada, either get the paperwork right or ask for the all-US route and accept the extra hours.

What a Michigan move actually costs

Ground pet transport in 2026 runs roughly $0.50 to $1.60 per mile, with the low end reserved for shared routes on busy corridors and the high end for private or dedicated runs. Short hops do not follow the per-mile math, because minimum charges dominate anything under about 400 miles. Summer commonly runs 30 to 40 percent above the winter floor on the same route.

Michigan's advantage is that Detroit and the I-94 corridor sit on well-served lanes. Chicago is 285 miles away, which puts Michigan on the Chicago hub that feeds most of the eastern and midwestern shared-route network. Our Illinois pet transport guide covers that hub from the other side, and it is worth reading if your route touches Chicago at all. The disadvantage is everything north of Cadillac, where the shared-route logic stops working.

Treat every figure above as a planning range, not a quote. Actual pricing turns on crate size, the number of animals, whether the run is shared or dedicated, and how much flexibility you have on dates. A 90 pound dog in a giant crate can occupy the space of two medium animals and prices accordingly. Our breakdown of what it costs to ship a dog shows how those variables stack.

Booking a Michigan move without getting burned

Three Michigan-specific things belong on your checklist. First, confirm the operator knows Michigan requires a certificate for both dogs and cats with no owner-accompanied exemption, because an operator who assumes otherwise will have you scrambling for a vet appointment at the wrong end of the trip. Second, if the route touches the Upper Peninsula, ask which regional network the leg is being run off. Third, if the move happens between November and March, ask directly what happens if the bridge restricts high-profile vehicles or a lake-effect band closes I-94, and get the contingency in writing rather than a verbal reassurance.

Beyond that, the normal vetting applies: USDA registration where the operator carries animals commercially for others, real insurance, a written contract, and reachable references. Canine Cab is an independent editorial and referral service and does not transport animals itself, so the guidance in our piece on how to choose a pet transport company applies here exactly as it does anywhere. Book six to eight weeks out for a summer move and four to six for winter, and get the vet certificate scheduled to land inside the valid window rather than months ahead of it.
