- ArrivalPresent the certificate; clear the animal before going ashore.
On arrival & aboard
- At the dock
- What the PRDA regulations require is a certificate of veterinary inspection signed by an accredited veterinarian in the state or territory of ORIGIN, valid 30 days from the inspection date — carry it, and the rabies certificate, on arrival. They describe no advance-notice, appointment or arrival-inspection procedure for a private vessel, and the dogs-and-cats section is written for interstate movement: it says "Dogs and cats do not need a PRDA import permit for interstate movement" and refers animals originating outside the United States or its territories to the Federal Import Regulations instead. The only cited description of an examination on landing is a commercial site's, and it places it at the entry airport. Confirm with the Department of Agriculture before landing an animal.
- By yacht
- Sailing in from any foreign port makes this an international arrival into the United States even though Puerto Rico is US territory: the inherited CDC dog rules apply on top of these requirements, and PRDA says so itself — it refers animals originating outside the United States or its territories to the Federal Import Regulations, and points the reader to cdc.gov/dogtravel. Arriving directly from the US mainland or the USVI is domestic movement instead, and PRDA's dog-and-cat requirements are drafted for exactly that case: they speak of a veterinarian accredited "in the state or territory of origin" and of not needing a permit "for interstate movement". Both cited documents are in English, so no Spanish-language search was possible on the corpus; the regulation PRDA publishes in Spanish was not among them, and a conduct rule stated only there would not have been found. Nothing addresses an animal that stays aboard and never lands either, which is why there is no transit section — see verification.outstanding_questions.
Quarantine
No routine quarantine is described in the published regulations for compliant animals. The health certificate must state the animal did not originate from an area quarantined for rabies.confidence: Secondary. From a non-government source; treat as a lead, not gospel.[6]
Open questions
- Confirm the 6-month rabies window still stands — it is stricter than the usual 12 months and would force a booster for many visiting animals.
- Confirm whether any post-vaccination waiting period applies; the published regulations are silent.
- Confirm the arrival procedure for a private yacht (advance notice, inspection point, who to contact) — the regulations describe documents but not the process.
- Confirm which vaccines beyond rabies are mandatory; DHPP+L, Bordetella and FVRCP are listed by a secondary source only.
- Nothing addresses an animal that stays aboard and never lands, so no transit section is authored here.

Rabies
The animal must be properly identified and accompanied by a certificate of vaccination against rabies.confidence: Inferred. Backed by an official source but not yet certified by a human reviewer.[5]
Rabies titer test
A blood test that measures rabies antibodies, to show the vaccination actually took. The sample has to be drawn a set time after the jab, and some places then make you wait months more before the animal may land — so this is the requirement most worth checking before you plan a route, not after.
Veterinary health certificate
- Form
- Official state Certificate of Veterinary Inspection (CVI) — no single standard form, GlobalVetLink (approved eCVI provider), AgView (approved eCVI provider)
"All dogs and cats entering Puerto Rico shall be accompanied by an official health certificate stating that the animal did not originate from an area quarantined for rabies. An official certificate veterinary inspection signed by an accredited veterinarian in the state or territory of origin and will be valid for 30 days from the inspection date."

Parasite treatment

Identification
CDC requires dogs entering the United States to be microchipped, and the chip number must appear on any accompanying rabies documentation. A territory may accept a collar tag for its own local rule, but that does not replace the federal microchip requirement for a dog arriving from abroad.[24]
"If your dog's microchip number starts with a number other than 9, be sure to check with your veterinarian that it is readable. If the microchip cannot be scanned on arrival for a dog that has been in a high-risk country, the dog may be denied entry and returned to the country of departure at the importer's expense."[4]
Puerto Rico's own rule accepts either a microchip or a collar with a metallic ID tag as official individual identification. The inherited CDC requirement is stricter for dogs arriving from a foreign port, where a microchip is required — so a chip is the safer choice for a cruising boat.[52]

- Dogs that have been in a high-risk rabies country in the previous 6 months face additional requirements: a rabies serology/titer and, in some cases, a CDC import permit. Which countries those are is not a judgement call — see the note below for CDC's list and the eight destinations on this site that are on it.confidence: Inferred. Backed by an official source but not yet certified by a human reviewer.[43]
- SCREWWORM CERTIFICATE — USDA/APHIS, and separate from anything CDC asks for. 9 CFR 93.600(a): "Dogs from any region of the world where screwworm is considered to exist may only be imported into the United States if they meet the requirements of paragraphs (a)(1) and (2)". Those are: "(1) Dogs must be accompanied by a certificate signed by a full-time salaried veterinary official of the region of origin stating that the dog has been inspected for screwworm within 5 days preceding its shipment to the United States" and "(2) The certificate must state that the dog is either free from screwworm or was found to be infested with screwworm and was held in quarantine and treated until free from screwworm prior to leaving the region of origin." READ THAT AS A CRUISER: it is not your own vet's certificate, it is a GOVERNMENT veterinary official's, it must be within FIVE DAYS of departure, and on many islands finding a full-time salaried government vet at short notice is the hard part. APHIS maintains the list of affected regions at aphis.usda.gov (Animal Health Status of Regions) and changes it by administrative action, so check it against your actual last port rather than assuming — this dataset does not reproduce the list. Cats are not covered: subpart F is headed "Dogs". The quoted paragraphs have been checked against the regulation: subpart F is now held in this repository, fetched from the eCFR XML API, and both quotes above appear in it verbatim.confidence: Inferred. Backed by an official source but not yet certified by a human reviewer.[1]
THE DOMINICAN REPUBLIC IS HIGH RISK, AND THIS FILE SAID OTHERWISE UNTIL 2026-10-03. CDC's list is headed "These countries and political units are considered high risk for importing dog rabies into the United States" and it names the Dominican Republic. Eight destinations on this site are on that list: Belize, Colombia, the Dominican Republic, Guatemala, Guyana, Honduras, Suriname and Venezuela. The Bahamas, Turks & Caicos and the BVI are not on it, and neither is Nicaragua. US territories are not foreign countries for this purpose. The claim this replaces grouped the Dominican Republic with the not-high-risk islands and told a cruiser returning from there that the titer "does not normally apply" — it does, and a US-vaccinated dog also needs the Certification of U.S.-issued Rabies Vaccination form endorsed before it leaves the United States, which cannot be arranged afterwards.[3]
