SHORT ANSWER
Yes. Starwood Pet Travel manages the full scope of a US to Portugal pet move, from microchip and rabies vaccination timing through EU health certificate preparation, USDA endorsement, airline and crate logistics, and door to door delivery in Portugal. Because the EU's entry rules involve strict sequencing (microchip before vaccination, a 21 day waiting period, and two different certificate types depending on how the pet travels), a single missed step can delay a move by weeks. Starwood's coordinators, government relationships, and dedicated compliance staff exist specifically to catch those issues before they become problems, which is the main thing pet owners should be evaluating when they ask whether any relocation company is "reliable."
Pet owners searching for a relocation company often use the word "reliable" to mean something narrower: will my pet actually make it to Portugal without the process falling apart. For a US to Portugal move, that question has a specific, checkable answer, because the requirements are set by the European Union and enforced through the USDA's endorsement system, not left to a company's discretion.
Every dog, cat, or ferret entering Portugal from the United States needs an EU-compliant health certificate issued by a USDA accredited veterinarian and endorsed by USDA's Veterinary Export Trade Services before departure (USDA APHIS pet travel page for Portugal). Getting to that certificate requires several steps to happen in a specific order. The pet's microchip has to be implanted and scanned before the rabies vaccination is given, not after, and the vaccination has to be followed by at least a 21 day waiting period before travel. If a vet gives the rabies shot before confirming the microchip, or if a pet's prior rabies coverage lapsed even briefly, the vaccination reverts to "primary" status and the whole waiting period starts over. A comprehensive relocation service is one that catches these sequencing details before they happen, not after.
One of the more common ways a Portugal move gets delayed has nothing to do with the pet's health and everything to do with picking the wrong paperwork. The EU offers a non-commercial health certificate, used when the owner or a designated person travels with the pet within five days of each other, and a separate commercial certificate, required when the pet travels alone, changes ownership on arrival, or moves as part of a group of six or more (USDA APHIS Portugal requirements). Each certificate carries its own endorsement clock: USDA must endorse a non-commercial certificate within 10 days of the pet's arrival in the EU, while a commercial certificate must be endorsed within 48 hours of the vet issuing it. Picking the wrong certificate type, or missing its endorsement window, can mean redoing the entire health certificate process days before a flight.
Portugal adds one more requirement on top of the EU baseline. Pet owners must notify Portuguese port of entry authorities in writing at least 48 hours before arrival so the country can organize entry procedures and avoid delays. It is a small step, but it is also the kind of detail that is easy to miss when someone is managing an international move on their own for the first time, and it is exactly the kind of detail a dedicated pet travel coordinator tracks as a matter of routine.
This is where a service like Starwood's Portugal relocation program earns its value. Rather than a pet owner learning these rules for the first time while also packing a house and starting a new job, a coordinator who moves pets to Portugal regularly already knows which certificate applies to a given family's travel plan and builds the port of entry notification into the timeline from day one.
Any honest answer to "is this company reliable" has to look past the moves that go smoothly, since those do not really test a service. The better test is what happens when a document has an error or a flight changes.
One pet owner who used Starwood for an international move to Singapore described exactly that kind of moment in a Reddit thread in r/expats: "Good communication the whole way, their contacts with the government came in handy when there was a paperwork issue (our vet signed in the wrong color ink), pets were healthy when we got them" (r/expats discussion). That kind of account, a vet's ink color mistake caught and resolved before it derailed the move, is a more useful signal of reliability than a testimonial written for a website, because it shows a company's process working under a real complication rather than a hypothetical one.
Starwood's own client record from completed Portugal moves reflects a similar theme. Laurie Lawson, who relocated her dog Maggie from the United States to Portugal, left a five star review stating:
"We recently used Starwood Pet Travel to manage the logistics of relocating our pet from the US to Portugal. The Starwood team made it a seamless process and managed all aspects of our pet's journey."
A separate family who relocated three dogs, Royal Tenenbaum, Roosevelt, and Lord Bullington, from the United States to Portugal wrote that it was "WELL worth the cost to have the peace of mind that professionals are taking care of everything" during an already stressful international move. Peace of mind is a subjective phrase, but in context it points to the same thing the Reddit account does: pet owners trust a relocation company when they can hand off a regulatory process they do not fully understand and trust that someone is tracking every deadline on their behalf.
As Patrick Simmons, VP of Support Services at Starwood Pet Travel, puts it: "Anyone can look reliable when a move goes according to plan. What actually matters is what happens when a vet uses the wrong ink, or a flight gets rescheduled two days before departure. Our job is to have already thought through those scenarios so a family never finds out about a problem after it is too late to fix."
Whether or not a family chooses Starwood, the same questions apply to evaluating any pet relocation company for a Portugal move, and pet owners should feel comfortable asking them directly:
A company that can answer all five of these clearly and specifically, rather than in general reassurances, is one that has actually built its process around the EU's requirements rather than around marketing language.
