Most pet parents know the obvious checklist items — crate, documents, food. But when it comes to what actually travels inside and alongside the carrier on moving day, a lot of people are guessing. Some pack too much. Some leave out the things that would actually help. And a few unknowingly pack items that will be removed at check-in.

Here’s what should actually be in your pet’s go-bag, and why it matters more than you might think.

First: The Carrier Itself Is Not Negotiable

Before anything goes in the carrier, the carrier itself has to be right. Airlines follow IATA Live Animals Regulations, which means the crate needs to be hard-sided, non-collapsible, ventilated on all sides, and secured with metal nuts and bolts — not plastic snap clips. Your pet needs to be able to stand, turn around, and lie down comfortably, with 3–4 inches of headroom above their head.

If you’re unsure whether your current carrier qualifies, have it reviewed before travel day. Carriers that don’t pass inspection get rejected at check-in, and that’s a problem you don’t want to deal with at the airport.

What Goes Inside the Carrier

An absorbent pad or thin bedding

Accidents happen in transit, and thin absorbent bedding helps manage that without creating a bulky obstruction. The key word is thin — it can’t raise the floor of the carrier enough to cut into your pet’s headroom. A flat absorbent pad works well.

A worn piece of your clothing

This is one of the most practical things you can do for an anxious pet, and it costs nothing. A worn T-shirt or small towel that smells like you gives your pet a familiar scent anchor for the entire journey. Pack something you don’t mind losing — it may get soiled and discarded en route.

Dry food in a sealed clear bag

If your pet’s itinerary includes a layover or rest stop, airline staff may feed them at their discretion. Pack enough dry food for each day of travel in a clearly labeled, sealable clear bag attached to the outside of the carrier. No wet food, no raw food;  it won’t be accepted.

Water cups mounted to the carrier door

IATA-compliant carriers are required to have two food and water cups mounted inside the metal gate door. These need to be in place and accessible before check-in. An optional drip water bottle can also be mounted above the cups.

What Does NOT Go in the Carrier

This is where it’s worth being explicit, because the instinct is to make the carrier feel like home, and that instinct leads to items getting confiscated or creating a safety risk.

• Toys, stuffed animals, and bones are prohibited. They’re a choking hazard in a confined space without supervision, and airlines will remove them.
• Collars, ID tags, and AirTags/Smart Tags should be removed before travel. Collars and tags can snag on the gate door. Your pet will be identified by their microchip and the paperwork attached to the carrier; that’s what counts at customs and during handoffs.
• Leashes don’t travel inside the carrier, but if you’re sending one along, keep a spare at home. They frequently go missing at check-in.
• Large beds, blankets, or pillows interfere with height requirements and aren’t worth the risk of having the carrier flagged.
• Anything irreplaceable. Sentimental items may be discarded if soiled or flagged. Don’t send something you’d be upset to lose.

The Bag That Travels With the Carrier

When WorldCare Pet arranges your pet’s move, certain items travel attached to or alongside the crate rather than inside it. Here’s what to have ready:

Original documents — not copies

This one is critical and often misunderstood: airlines and customs authorities in most countries will not accept photocopies or digital versions of your pet’s travel documents. The originals (health certificate, government endorsements, vaccination records, import permits, and any required test results) must physically travel with your pet. Your WorldCare relocation counselor will organize and attach these to the carrier so they’re present at every checkpoint.

Labeled medications

If your pet takes regular medication and your vet has approved in-transit dosing, pack clearly labeled medications with dosage instructions. Note: whether or not they get administered in transit is ultimately at the airline’s discretion — WorldCare can request it, but it cannot be guaranteed.

Feeding instructions

Write out your pet’s normal feeding schedule, portion sizes, and any dietary notes. This travels attached to the carrier so anyone handling your pet has the information they need.

Your emergency contact information

Attached to the outside of the crate and documented with your relocation counselor. If anything needs to be escalated in transit, the right people can reach you immediately.

One Thing That Won’t Make the Cut — Ever

Sedatives and tranquilizers are prohibited. Airlines won’t accept a pet that appears sedated, and for good reason. Sedation impairs a pet’s natural balance and ability to brace during movement, which increases injury risk. If your pet experiences anxiety, crate acclimation in the weeks before travel is the most effective intervention. A familiar scent inside the carrier also helps significantly.

The Short Version

• Inside the carrier: thin absorbent bedding, a worn piece of your clothing, and mounted water and food cups.
• Attached to the outside: original travel documents (no copies), dry food in a clear bag, labeled medications if applicable, feeding instructions, and your emergency contact info.
• Not in the carrier: toys, bones, collars, ID tags, large beds, AirTags, or anything irreplaceable.

Get the carrier right first. Then pack it right. Your pet’s comfort on travel day depends on both.
