This is a specific conversation about Dog travel crates — safe and airline-approved — ask about yours and get one honest answer for your exact situation.

Travel crates have very specific requirements depending on whether your dog is travelling by car, in the cabin, or in the hold — and airline rules vary significantly between carriers, so getting this wrong can mean your dog simply isn't allowed to board. Before I can point you to the right crate, I need a few details: what breed and size is your dog, how are you travelling (car, cabin, or hold), and if you're flying, which airline are you booked with?
She's a 3-year-old Toy Fox Terrier. We're flying internationally but I'm not sure if she qualifies for cabin — I think she weighs about 3.5kg. We're flying with British Airways.

Good news and a complication: British Airways does allow small dogs in the cabin on some routes, but their limit is typically 8kg combined weight of dog plus carrier, and the carrier must fit under the seat in front — usually around 46cm x 30cm x 23cm max. At 3.5kg, your Toy Fox Terrier is well within the weight limit on the dog side, so it really comes down to which carrier you use and whether the route permits cabin pets at all. International routes with BA can vary, so you'll need to confirm your specific route with them directly. That said, you're in a good position to plan for cabin travel. Can you tell me roughly her dimensions — length from nose to base of tail, and height at the shoulder?
She's about 35cm nose to tail and maybe 28cm tall at the shoulder. Pretty compact little dog.

She'll fit comfortably. For a Toy Fox Terrier of those dimensions on a cabin flight, I'd recommend the Sleepypod Air In-Cabin Pet Carrier. It's specifically designed for airline cabin use — the soft-sided construction compresses slightly to fit under most aircraft seats, it meets the dimensions required by BA and most major carriers, and it has a sturdy internal frame so your dog isn't cramped. The Sleepypod Air is 46cm x 25cm x 28cm, which sits right within BA's under-seat allowance. At 3.5kg, your dog has plenty of room, and the padded interior and top-entry design mean she can settle rather than stress — important on her first international flight. It's available on Amazon UK and consistently recommended by frequent pet travellers for exactly this use case. One thing: book her place in the cabin with BA as soon as possible — they limit the number of pets per flight and it fills up fast.
That's really helpful. Is there anything I need to do to prepare the crate before the flight so she's comfortable in it?
inparticular.ai
Yes — crate familiarisation before the flight makes a real difference, especially since this is her first time flying. Start leaving the Sleepypod Air open at home a couple of weeks before travel so she can explore it at her own pace. Feed her meals near it, then inside it, so she associates it with something positive. A few days before the flight, do short zip-up sessions so she gets used to being enclosed. Bring a small item with your scent inside — a worn t-shirt or her usual blanket — to help her settle. Avoid feeding her a large meal in the two to three hours before the flight to reduce the chance of nausea. She'll be much calmer if the carrier already feels like a familiar, safe space rather than something new and alarming.
Perfect. And do I need any specific documentation for her to fly?

For international travel with a dog you'll typically need: a microchip (ISO standard 15-digit), a valid rabies vaccination, and an official health certificate issued by a vet — for most routes this needs to be done within 10 days of travel. If you're entering the EU or returning to the UK, you'll also need an Animal Health Certificate (AHC) rather than the old pet passport, issued by an Official Veterinarian. The exact requirements depend entirely on your destination country, so check the official government guidance for that specific country as early as possible — some destinations have additional requirements or waiting periods that can take months to satisfy. Your vet will know what's needed, but give yourself at least 8 weeks to sort the paperwork side.
