Travel Essentials for Small Dogs: The 2026 Packing List

Why small dogs are the easiest travellers

A small dog can fly in the cabin with you, sit on your lap in the car and fit in most hotel rooms. That makes it the easiest dog to travel with, but only if you pack the right things.

The essentials come down to four groups: a carrier the airline accepts, the papers the border asks for, the kit that keeps your dog fed and calm, and a plan for the day itself. This list covers each one, with the airline rules taken from the Pet Holiday Club rules base.

The small dog travel essentials checklist

Pack these 15 items and your small dog is ready for a flight, a road trip or a hotel stay.

Carrier and gear

• Airline-approved soft-sided carrier that fits under the seat

• Absorbent pad for the carrier floor

• Harness and spare leash (collars slip off small dogs easily)

• ID tag with your mobile number and destination address

Papers

• Microchip number, written down and matching every document

• Rabies vaccination certificate

• Health certificate or import form for your destination

• Airline pet reservation confirmation

Food, water and health

• Usual food in a sealed container, plus one extra day's worth

• Collapsible water bowl and a bottle of water

• Any daily medication, in its original packaging

• Poop bags and pet wipes

Comfort

• A worn T-shirt or blanket that smells of home

• One familiar chew toy

• A light jumper for cold cabins (small dogs lose heat fast)

Essential 1: a carrier your airline accepts

The carrier is the one item that decides whether your dog flies. Most US airlines want a soft-sided carrier of about 18 × 11 × 11 in (46 × 28 × 28 cm) that fits fully under the seat in front.

European carriers are stricter on weight: 8 kg including the bag. Read our Lufthansa and KLM reviews if you are flying to Europe.

What to look for in the carrier itself:

• Mesh on at least two sides for airflow.

• Room for your dog to stand and turn around.

• A leak-proof base and a zip your dog can't nose open.

• Your name and phone number on the outside.

Buy the carrier at least two weeks early and let your dog nap in it at home. A dog that already treats the bag as its bed stays calmer on the day.

Check your exact flight on the airline guides before you buy: dimensions can change by aircraft.

Essential 2: the right papers, in the right order

Size doesn't change the paperwork: a 6 lb Chihuahua needs the same documents as a Great Dane. For most international trips, the order is:

1. Microchip first. An ISO 11784/11785 15-digit chip, implanted before the rabies shot. A rabies vaccine given before the chip may not count.

2. Rabies vaccination. Your dog must be at least 12 weeks old, and many countries need the shot at least 21 to 30 days before travel.

3. Parasite treatment. Flea, tick and worm treatment, often within 10 days of travel.

4. Health certificate or import form. Issued close to departure. Dogs entering the US need a CDC Dog Import Form receipt and must be at least 6 months old.

Lead times differ by destination, so check the country guide for where you are going. Keep scans of every document on your phone, or store them in a digital Pet Passport.

Book a vet check a week or two before you fly, even for domestic trips. Small breeds are prone to dental and heart issues that stress can make worse.

Essential 3: food, water and a calm dog

Small dogs burn energy fast and dehydrate quickly, so feeding and water need more planning than for a large dog.

• Feed lightly. Give a small meal 3–4 hours before departure, not right before. A full stomach on a bumpy flight often comes back up.

• Offer water little and often. A few sips at a time avoids accidents in the carrier.

• Watch for low blood sugar. Toy breeds can get shaky or lethargic if they skip meals. Pack a few treats and ask your vet what to carry.

• Bring familiar smells. A worn T-shirt in the carrier does more than most calming products.

If your dog drools, licks its lips or vomits in the car, it may be motion sickness rather than nerves. Our guide to dog motion sickness covers what vets prescribe. For a dog that panics, read what actually helps with dog travel anxiety.

Never sedate a dog for a flight without your vet's advice. Sedation can affect breathing and balance at altitude, and many airlines refuse sedated pets.

Essential 4: a plan for travel day

Arrive 2–3 hours before a flight with a cabin dog. Pet check-in takes longer than a normal bag drop, and agents may ask to see your papers and weigh the carrier.

• Book your dog's seat early. Airlines cap the number of pets per cabin, and spaces go first on busy routes.

• Walk your dog before security. Many US airports have pet relief areas, but some sit outside security.

• Plan for screening. At US security you carry your dog through the scanner while the empty carrier goes through the X-ray. A snug harness and leash make this safer.

• Keep the carrier zipped on board. The dog stays inside, under the seat, for the whole flight.

On arrival, find water and a relief spot first. If you are staying in a hotel, check the pet fee and weight limit before you book: our comparison of hotel chains that take dogs lists both for 13 chains.
