Essential Checklist & Tips for a Smooth Landing

Moving to a new country is a lot for a pet. New smells, new sounds, a new home layout, and often a long travel day or days, can leave dogs and cats tired, confused, or overstimulated. The goal for day one is simple: safety, hydration, calm, and a predictable routine.

On your pet’s first day in a new country: set up a quiet “safe room,” offer small amounts of water and a light meal, keep routines simple, do a quick health check, take a short leash walk (dogs), keep cats indoors, and schedule a local vet visit within the first week. Watch for vomiting, diarrhea, extreme lethargy, trouble breathing, or refusal to drink; those are reasons to contact a vet right away.

The First-Day Essentials Checklist

1) Safety first: secure the space before your pet explores

Do this before opening the carrier:

• Close doors and windows, and check screens/locks.
• Remove hazards like cleaners, small objects, cords, and toxic plants. Some dogs may chew as part of exploring a new space.
• Choose a quiet room as a safe zone (especially important for cats).

Set up the “safe room” with:

• Fresh water and a second water bowl if your pet is nervous
• Familiar blanket/bed that smells like home
• A few favorite toys (to keep your cat and dog calm)
• Litter box for cats (in a separate corner away from food/water)
• Pee pads (helpful for travel-stressed pets or apartment arrivals)

2) Do a quick health check

When your pet is calm, do a gentle look-over:

• Watch for any signs of discomfort or unusual behavior. It is common for pets to become disoriented, tired, or restless after a flight but be sure to manage their behavior closely.

Call a vet urgently if you notice:

• trouble breathing, persistent coughing, collapse
• repeated vomiting, bloody diarrhea
• severe lethargy (can’t stand / won’t respond normally)
• signs of heat stress (heavy panting and weakness)

3) Food and water

Once you arrive at your new home, avoid giving your pet a full meal or lots of water right away. Offer small amounts first (about half their usual portion), then offer a little more about an hour later. Don’t encourage fast eating or drinking.

Water

• If your pet won’t drink, try ice cubes, a splash of low-sodium broth, or a second bowl in a quieter spot.

Food

• Stick to their usual food if possible.
• Avoid rich treats and new chews on day one.

4) Bathroom plan: expect timing to be different

Dogs

• Do a short leash walk soon after arrival; quiet route, low stimulation.
• Keep it short. Today is not for exploring.

Cats

• Keep cats indoors and in the safe room at first.
• Show them the litter box right away.
• Don’t move the litter box repeatedly on day one; consistency helps.

Normal on day one: reduced appetite, extra sleeping, clinginess or hiding, mild stomach sensitivity.
Not normal: persistent vomiting, repeated diarrhea, refusal to drink, signs of pain.

5) Keep routines simple and familiar

Pets adjust faster when the first day feels predictable.

• Feed at your normal time (or as close as possible).
• Keep the lighting calm in the evening.
• Limit visitors and exciting outings.
• Use the same cue words and calm tone you use at home.

Country-to-country “must-dos” most pet parents miss

Even when entry paperwork is done, these steps help you avoid headaches later:

Register locally (when applicable)

Depending on the country/city, you may need to:

• register your pet with a local municipality
• update microchip details with a local database
• purchase a local pet license (often required for dogs)

Line up a local vet early

Book a wellness visit within the first 7–14 days, sooner if:

• your pet has ongoing meds
• you need refills
• your destination requires local registration tied to a vet

Bring:

• vaccination history and microchip number
• travel documents (digital copies and printed)
• any current prescriptions

Tips to help your pet adjust faster (dogs and cats)

For dogs

• Keep walks short and consistent for the first few days.
• Avoid dog parks until your dog is fully settled and you understand local norms.
• Practice “calm greetings” with neighbors, new people can be overstimulating.

For cats

• Use a slow expansion method: safe room to one extra room to whole home.
• Add hiding spots and vertical spaces (cat tree/shelves) to build confidence.
• Consider pheromone diffusers if your cat is prone to stress.

First Day After an International Pet Move: FAQs for Pet Parents

How long does it take for a pet to adjust to a new country?

Most pets begin to settle within a few days to a few weeks. Cats often take longer than dogs, especially after long travel days. Routine and a calm environment speed it up.

Should I bathe my pet after international travel?

Usually not on day one unless they’re visibly soiled. A gentle wipe-down and brushing is often enough. Before your pet travels, it’s recommended to trim their nails (to help prevent injury) and schedule a grooming appointment. If you’re relocating from a cooler climate to a warmer one, a shorter coat can be especially helpful.

Is it normal if my pet won’t eat after the flight?

A reduced appetite for 12–24 hours can be normal. Focus on hydration and offer small, familiar meals. If your pet refuses food beyond 24 hours (or won’t drink), contact a vet.

Can I take my pet out to explore right away?

Keep it minimal on day one. Dogs should do short, quiet leash walks. Cats should stay indoors until they’re clearly comfortable and your home is fully secured.

What are signs my pet is not adjusting well?

Persistent vomiting/diarrhea, continuous pacing/panting, refusal to drink, hiding with no improvement over days (cats), aggression that escalates, or signs of pain are reasons to speak with a vet.
