Taking Your Pet Abroad vs. Leaving Them at Home: Where to Check the Rules

Away Mode ยท Last reviewed 2026-10-16

When planning an extended international trip, deciding whether to bring a dog or cat or arrange care at home is one of the most consequential decisions an owner makes.

While travelling with a companion animal sounds appealing, international pet travel involves strict health protocols, multi-month timelines, and significant stress for the animal. Here is an objective look at the trade-offs, along with the official government resources you must check before making plans.

Key Trade-Offs to Weigh

1. Environmental Stress and Airline Transit

  • Air Travel Realities: Except for small pets that meet strict airline in-cabin weight and carrier size limits, animals must travel as manifested cargo or checked baggage in temperature-regulated holds. Cargo transit involves loud environments, unfamiliar handlers, temperature holds, and tarmac delays.
  • Feline Sensitivity: Cats are territorial creatures that orient themselves through scent and established territory. For almost all domestic cats, a temporary international trip causes far more distress than staying in their familiar home environment with daily visits or a trusted house sitter.
  • Acclimatisation: New smells, street noise, quarantine inspections, and foreign parasites (such as sandflies or foreign tick species) present real health and comfort challenges once abroad.

2. The Return Journey to the United States

Bringing a pet back into the United States is governed by federal import regulations:

  • The U.S. Centers for Disease Control and Prevention (CDC) maintains strict entry rules for all dogs entering or returning to the U.S. (including dogs originating in the U.S.). Requirements include an official CDC Dog Import Form receipt, an ISO-compatible microchip implanted prior to any required rabies vaccination, and specific veterinary documentation depending on whether the dog visited a high-risk rabies country.
  • Rules vary widely between dogs and cats, and regulations update regularly based on global animal disease status.

Where to Verify Official Entry Requirements

Never rely on travel blogs, forum threads, or third-party pet relocation guides for international entry requirements. A missing endorsement or wrong vaccine timeline can result in refusal of entry, mandatory quarantine at owner expense, or return deportation of the animal.

Always verify rules directly through official government authorities:

1. USDA Animal and Plant Health Inspection Service (APHIS)

The primary U.S. government clearinghouse for taking animals abroad is the USDA APHIS Pet Travel Portal:

  • Official Resource: USDA APHIS Pet Travel (aphis.usda.gov/pet-travel).
  • This tool allows you to select your destination country from a comprehensive list to view the exact requirements: microchip specifications, rabies blood titers (FAVN testing), waiting periods, and international health certificate forms.
  • Most destinations require an International Health Certificate completed by a USDA-accredited veterinarian and endorsed digitally or physically by USDA APHIS within a narrow window (often 10 days) prior to travel.

2. U.S. Department of State: Travelling with Pets

  • Official Resource: U.S. Department of State Pet Travel (state.gov/traveling-with-pets/).
  • Provides baseline guidance on consular resources, overseas veterinary considerations, and country-specific travel alerts.

3. Destination Country Agricultural and Quarantine Ministries

Verify requirements directly with the destination country's agricultural agency before scheduling travel:

  • European Union: European Commission rules on non-commercial movement of pet animals (food.ec.europa.eu).
  • United Kingdom: Department for Environment, Food & Rural Affairs (DEFRA) pet travel scheme (gov.uk).
  • Japan: Ministry of Agriculture, Forestry and Fisheries (MAFF) animal quarantine service (maff.go.jp).
  • Australia: Department of Agriculture, Fisheries and Forestry (DAFF) bringing cats and dogs to Australia (agriculture.gov.au). Strict biosecurity requires import permits and mandatory quarantine periods.

When Leaving Your Pet at Home Makes the Most Sense

In most situations, arranging reliable care in your pet's home environment is the safer, less stressful choice if:

  • Your total absence is under 30 to 60 days.
  • Your destination country requires mandatory quarantine upon arrival (such as Australia, New Zealand, or Japan without 180-day advance blood titer protocols).
  • Your pet is a senior, has chronic medical conditions, or exhibits high anxiety in transit.
  • Your itinerary involves multiple train or flight transfers, non-pet-friendly hotels, or frequent location changes.
