The questions we are asked most. If yours is not here, email us — we answer within a day on weekdays.
Sizing
How do I know which size to buy?
Every product page lists the measurements and the size or weight of dog it suits. Measure your dog from chest to base of tail while they are standing, and check their weight. If you are between sizes, email us the breed and weight and we will tell you which to choose.
My dog is a mix. What then?
Go by weight and body length rather than breed name. Send us both and we will give you a straight answer.
What if the size is wrong when it arrives?
Send it back within 30 days and we will exchange it or refund you. See our Refund & Return Policy.
Will My Dog Actually Use It?
My dog has refused things before.
It is the most common worry we hear, and an honest answer helps more than a confident one. Most dogs take a few days to settle into a new seat or bed. Putting a familiar blanket in it for the first week helps considerably.
If yours simply will not take to it, return it within 30 days. You do not need to justify the decision to us.
Will it stop my dog being anxious in the car?
We cannot promise that, and we will not pretend to. What we can tell you is what the design does: it raises a dog to window height so they can see out, and it keeps them in one place instead of sliding around. Many owners find that makes a difference. Some dogs are anxious for reasons a seat cannot fix.
Safety
Are your car seats crash-tested?
No. Our car seats are travel accessories, not certified safety restraints, and we do not hold independent crash-test data. If certified crash protection is what you are looking for, buy from a brand that has paid for that testing. We would rather lose the sale than mislead you.
Can I use one on the front seat?
We recommend the rear seat, as you would with a child seat. Airbags are designed for adult humans.
Delivery
How long will my order take?
6–11 business days in total: 2–3 days processing, then 4–8 days in transit. Full detail is in our Shipping Policy.
How much is delivery?
Free on every UK order, with no minimum spend.
Where do you ship from?
From our overseas fulfilment centre, direct to you. We say so plainly here and on our About page, because finding it out after ordering is nobody’s idea of a good surprise.
Do you ship outside the UK?
Not at the moment. We ship across the United Kingdom, including Northern Ireland, the Highlands, and the Islands.
Will I pay customs charges?
No. Any duties or import taxes are covered by us. If a carrier ever asks you for money, send us the paperwork and we will reimburse you in full.
How do I track my order?
You will get a tracking number by email when your parcel is dispatched. See Track Your Order.
Returns and Payment
What is your returns window?
30 days from delivery, with no restocking fee. This sits on top of your statutory rights, it does not replace them.
Who pays return postage?
You do if you have changed your mind. We do if the item is faulty, damaged, or not what you ordered.
What payment methods do you take?
Major debit and credit cards plus the digital wallets shown at checkout. Details are in our Payment Policy.
Can I cancel after ordering?
Yes, free of charge, any time before your order ships. Email us and we will stop it.
Care
Can I wash it?
It depends on the product, so each product page has its own care instructions. Some mats and cushions can go in the washing machine on a cool, gentle cycle; others, like the back seat extender, are made to be wiped clean instead. Whatever the product, air dry it fully and avoid the tumble dryer.
