SHORT ANSWER
The most common causes of delays when importing a pet to Italy are timing mistakes with the rabies vaccination, missing the narrow window in which a health certificate must be issued and endorsed before arrival, microchipping a pet after rather than before vaccination, and outdated information about which health certificate format is currently required. Because the United States is on the European Union's list of countries with a favorable rabies situation, dogs, cats, and ferrets moving from the US to Italy do not need the months-long rabies antibody titer test that trips up importers from other countries. That said, the process still hinges on a strict sequence of steps, and a single date entered incorrectly on a certificate, or a flight booked before the paperwork is finalized, can push a move back by weeks.
Because the United States sits on the European Union's list of countries with a favorable rabies situation (Annex II, Part 2 of Regulation (EU) 577/2013), American pet owners are spared the rabies neutralizing antibody titer test and its lengthy waiting period that dogs coming from non-listed countries must complete. That is genuinely good news, and it is also exactly why so many US-based movers underestimate the timeline. Italy's Ministero della Salute puts it plainly: "it is generally recommended to start the procedures in good time before the estimated date of departure, since the most complex of them may require more than 4 months" (Ministero della Salute, Travelling to Italy with Pets). Skipping the titer test does not mean skipping the planning. It just moves the risk to a different part of the timeline: the vaccination schedule, the certificate window, and the paperwork itself.
This is one of the simplest rules to follow and one of the easiest to get backward. Your pet's ISO-compliant microchip must be implanted and scanned by the veterinarian before the rabies vaccination is administered. If a vet vaccinates first and chips the animal afterward, the EU does not recognize that vaccination as valid, because there is no way to confirm which animal actually received it. The fix is not complicated: it simply means the vaccine has to be given again, and the 21-day (or longer) waiting period starts over. For families working backward from a moving date, that single sequencing error can cost three to four weeks they did not budget for.
Under EU rules that apply to Italy, a rabies vaccination is not considered protective, and your pet is not considered eligible to travel, until at least 21 days have passed after the primary vaccination (some manufacturers specify 30 days, and the vet records the correct figure on the certificate). Here is where owners get tripped up:
The practical fix is to pull your pet's full rabies vaccination history before you set a moving date, not after, so your vet can tell you immediately whether you are working with a primary vaccination timeline or a booster timeline.
This is arguably the most common cause of last-minute delays, because it interacts directly with flight bookings. Once a USDA-accredited veterinarian issues the non-commercial EU health certificate and it is endorsed, that certificate is only good for USDA endorsement purposes within 10 days of your pet's arrival in Italy. The certificate itself is valid for 30 days after issuance for travel purposes, but the endorsement has to land inside that 10-day arrival window.
In practice, this means the certificate cannot be finalized too early, and it cannot be finalized too late. If a flight gets rescheduled, canceled, or delayed by more than a few days on either side of that window, the certificate may no longer be usable, and the entire final-exam-to-endorsement sequence has to be repeated. This is why Starwood builds certificate appointments as close to departure as USDA processing realistically allows, rather than trying to get paperwork "out of the way" weeks in advance.
Pet owners moving to Italy this fall should know about a real, near-term change. Starting October 1, 2026, the EU requires a new non-commercial health certificate for dogs, cats, ferrets, and birds moving from the US, under EU Regulation 2026/131. According to USDA APHIS, certificates already in process on the old format can still be endorsed through September 30, 2026, but any certificate issued after that cutoff must use the new form (USDA APHIS Italy requirements). Anyone finalizing a health certificate in the last two weeks of September should confirm with their accredited veterinarian which version applies to their specific travel date, since this is exactly the kind of transition period where an outdated form can cause a certificate to be rejected for endorsement.
Checks on non-commercially moved pets happen at the traveler's actual point of entry into Italy, and Italy maintains a specific list of entry points where those checks are staffed (Ministero della Salute). Two mistakes show up repeatedly here. First, some travelers assume any Italian airport will do, when in practice pet checks are only resourced at designated points of entry. Second, and more common, is arriving with anything less than the complete original paperwork. USDA requires original ink endorsement on the health certificate itself, and copies are not accepted at the border. If your printed, endorsed certificate does not physically travel with your pet, expect the kind of delay that no amount of advance planning can fix after the fact.
As Adam Melton, VP of Strategic Initiatives at Starwood Pet Travel, explains: "Almost every delay we see on the Italy route traces back to a date, not a document. The paperwork itself is usually fine. It's the sequencing, chipping before vaccinating, booking a flight before the certificate window opens, that catches people off guard. We build our Italy timelines backward from the ten-day certificate rule for exactly this reason."
Reddit threads from people actually going through this process echo the same pressure points. In a discussion in r/expats about moving a dog from the US to Italy, one commenter laid out the paperwork sequence and flagged the timing risk directly: "Within 30 days of arrival (so 25 days out to give some flex time for delays) visit a USDA vet and get a full health certificate. Ensure you have a muzzle and a leash. Italy required all signs to be muzzled and leashed at all times when in public... When you arrive, see an Italian vet and start the process to get a EU Pet Passport, so that the dog can leave Italy and travel with you to other EU countries" (r/expats discussion). That instinct to build in flex time before the certificate window even opens is exactly the habit that prevents most of the delays described above.
Because the US is on Italy's favorable rabies list, the realistic minimum timeline for a healthy adult dog or cat with an up-to-date rabies booster can be as short as a few weeks. For a pet starting from a primary vaccination, plan for at least four to six weeks to clear the 21-day wait plus certificate scheduling, and build in buffer time around the health certificate's 10-day arrival window rather than treating it as a formality.

If your pet will be flying with a specific carrier, it is also worth confirming that airline's own pet policies well ahead of booking.
