The First 30 Days: Settling Your Newly-Arrived Pet in Tropical Asia

Most pet-relocation services hand you a clipboard at the airport, confirm the carrier matches the manifest, and consider their job done. What they don't tell you is that the first 30 days in Singapore, Bangkok, KL or Hong Kong are where pets either settle properly or develop the small problems that compound into expensive ones. This guide is the post-arrival plan we wish someone had written down for us.

Week one — the do-nothing week (almost)

The temptation in the first few days is to take your dog everywhere — show them the new neighbourhood, walk them at the park, introduce them to the building. Resist this. Cats are easier here because they self-isolate naturally. With dogs, the failure mode is the well-meaning owner who tires out a jet-lagged, dehydrated, climate-shocked animal in their first 48 hours.

What actually matters in week one:

• Same food, same routine. Whatever your pet was eating before the flight, keep them on it. Food brand changes during a stressful transition cause GI upset that everyone misreads as a "reaction" to the new country.
• One room first. Set up a single quiet room with bed, bowls, litter (cats), water, and the carrier left open as a familiar retreat. Let them explore the rest of the home over a few days, not all at once.
• Air conditioning on, low setting. 24–25°C indoors is fine. Pets that lived in a UK winter four weeks ago do not need to feel Singapore at 32°C and 85% humidity in week one.
• Short toilet walks only. Out, business done, back. No park visits, no off-lead, no meeting the neighbours' Schnauzer. Keep these to dawn or after dusk.

If your pet refuses food for the first 24 hours, do not panic. Offer water freely, offer the same food they were on before, and check again in 12 hours. A pet that won't eat or drink for over 24 hours is a vet call.

Week two — book the settling-in vet appointment

By the end of week two you want a relationship with a vet, not just a vet's name on a fridge magnet. The settling-in appointment is the most underrated thing on this list. It does four things at once:

• Registers your pet locally. Some cities require this for licensing; all of them require it for emergency continuity of care.
• Confirms vaccinations are current. Tropical Asia has different priority diseases — leptospirosis exposure is high in much of Singapore and Bangkok, and many UK pets arrive without a current lepto vaccine.
• Sets up parasite prevention. Year-round, not seasonal. Ticks carry diseases that don't exist in the UK, heartworm prevention starts immediately in Singapore and Hong Kong, and you'll want a flea-tick combination that suits your pet's species, weight and lifestyle.
• Gives you a relationship to call on. The clinic you call at 11pm with a wheezing dog should not be a clinic that has never met your dog.

Picking a vet well matters more than picking the closest one — but the closest one is almost always where pets end up the first time something goes wrong, so do the work upfront. We've written city-specific guides for Singapore, Bangkok and Hong Kong on what to look for in a first appointment and what good communication looks like.

Week two to three — parasites, the topic that surprised us

If you have only ever owned pets in a temperate country, parasite prevention in tropical Asia will be on a different scale. Heartworm is endemic in Singapore, Malaysia, Thailand and parts of Hong Kong's New Territories. Tick-borne diseases — Ehrlichia, Anaplasma, Babesia — are present year-round. Mosquito populations don't have a winter season to thin them out.

Most clinics will recommend a monthly oral or topical combination product that covers heartworm, fleas and intestinal worms, plus a separate tick preventative if you walk in grassed or wooded areas. The dosing is by weight; the schedule does not lapse. Skipping one month in this climate is enough to lose protection, particularly for heartworm which has a longer-than-monthly life cycle that monthly dosing is designed to interrupt at the right point.

Our parasites guide goes into the specifics. The 60-second version: ask the vet at your settling-in appointment what they put their own pets on, and budget for it as a permanent monthly cost.

Week three — acclimatising to heat, properly

Acclimatisation is real and it takes time. Most healthy adult dogs and cats need four to eight weeks of consistent low-level exposure to adapt — they get better at panting efficiently, their fluid balance settles, and they tolerate humidity better. The way you get there is gradually:

• Walks at the cooler ends of the day, building duration over weeks rather than days.
• Short windows of milder indoor temperature (26–27°C) for a few hours daily by week three or four, so they're not entirely AC-dependent.
• Hydration available everywhere. A water bowl in every room they use, plus a portable bottle on walks.
• Honest assessment of breed risk. If you have a brachycephalic dog or cat (pug, French bulldog, Persian, Himalayan), they will not fully acclimatise. They are permanent indoor pets here with very short outdoor windows. There's no shame in this — it's biology, not training.

The single rule that catches owners out: panting is a dog's only real cooling mechanism, and it stalls at high humidity. A 30°C day with 90% humidity is significantly more dangerous than a 35°C day at 40% humidity. Most heat emergencies in Singapore happen on warm, still afternoons with cloud cover — not on the days that look obviously hot. Our heat stress guide covers the warning signs in detail; the executive summary is that any pet that pants harder than the conditions warrant, refuses to move on a walk, or develops bright red gums needs cooling and shade immediately.

Week four — the practical maintenance list

By week four you should have most of the following set up. Use this as a checklist:

• A registered vet with at least one in-person appointment on file.
• A 24-hour emergency clinic identified — name, address, phone — saved to your phone before you need it. Ask your regular vet which one they refer to.
• Monthly parasite prevention on a calendar reminder.
• Pet insurance decision made one way or the other. Premiums in Singapore and Hong Kong are higher than UK rates and exclusions are sharper; for some owners self-insurance via a dedicated savings account is the better answer. Our pet insurance guide walks through the actual numbers.
• Food brand sourced locally. If the brand isn't easily available here, transition over 7 to 10 days to one that is — sudden swaps cause GI issues.
• A boarding option researched for your first business trip or holiday. Good boarders fill up quickly, particularly around Chinese New Year, the December–January window and the summer school holidays.
• Microchip details updated to your new local address and phone number — the chip number doesn't change, but the contact details on the chip registry need to.

When to call the vet anyway, regardless of week

The signs below mean call now, not "see if it gets better":

• Vomiting more than once in 24 hours, particularly if blood is present.
• Refusal to eat or drink for more than 24 hours.
• Laboured or noisy breathing at rest (not after exertion).
• Lethargy that worsens rather than improves.
• Bright red, very pale, or blue-tinged gums.
• Diarrhoea with blood or mucus, or persistent diarrhoea over 48 hours.
• Any temperature over 39.5°C taken rectally.
• A wound, lump or swelling that wasn't there yesterday.

Cats hide illness better than dogs, so the bar for calling is lower with cats — a cat that has stopped grooming, is hiding more than usual, or has changed litter habits for more than two days is worth a vet conversation even if nothing else looks wrong.

Six-week perspective

By the end of week six most pets are well into the new normal. They've adjusted to the climate, the household, the food, the new routines. The owners who report the smoothest transitions are the ones who slowed everything down in the first fortnight — kept the world small, kept routines familiar, and trusted that acclimatisation would happen on its own timetable rather than theirs.

The owners who report the rough transitions usually share a pattern: too much, too soon. Park visits in week one. A food brand switch in week two because the local pet shop didn't stock the old brand. Skipping the settling-in vet appointment because the pet "seemed fine". Cumulatively these compound into a pet that's stressed, slightly unwell, and harder to settle.

The honest version of pet relocation isn't airport-to-living-room. It's airport, then six weeks of patient unhurried adjustment. If you've already done the hard work of getting them here, the post-arrival month is what makes it worthwhile.
