Shop medium dog car seats built for breeds such as Cocker Spaniels, Border Collies, Beagles and Bulldogs. A car seat for medium dogs needs a wider base and stronger anchor points than a small dog booster, since most elevated boosters are only rated up to around 12 to 14kg.
Why Choose a Medium Dog Car Seat?
✓ Wider base and reinforced anchor points built for medium sized breeds
✓ Keeps your dog in one place, cutting driver distraction
✓ Non slip base and padded bolsters add stability
✓ Removable, machine washable covers for easy cleaning
Elevated Base or Non Elevated?
Medium dogs generally do better with an elevated base or non elevated seat rather than a small dog style booster, which is usually rated only up to 12 to 14kg.
Elevated
Attaches to the headrest. Best suited to smaller dogs up to around 12 to 14kg.
Elevated Base
Sits on the seat with a raised, padded base. A strong fit for most medium dogs.
Non Elevated
Sits flat with padded sides. Suits calmer or heavier medium dogs.
Breed and Weight Guide
This range is generally positioned for medium breeds roughly in the 10 to 25kg range. Weight limits vary between individual products, so check the exact figure stated on the product you are considering rather than assuming every seat takes the same maximum weight.
Medium, Small or Large: Which Collection Do You Need?
Small Dog
Elevated view, settles well raised up, up to around 12 to 14kg
Medium Dog
Wider base, stronger anchors, roughly 10 to 25kg
Large or Multiple Dogs
Extra width for one large dog or two dogs together
How to Measure Your Medium Dog
Weight, using scales
Body length, neck base to tail base
Seated height, floor to top of head
Chest size, widest point behind front legs
Vehicle Compatibility
Most medium dog car seats are designed for the rear seat, secured using headrest straps, a lower seat strap, or both. Check whether your rear headrests adjust or remove so the straps can loop through, whether the seat leaves your seat belt buckle accessible if you also carry a passenger, and whether it fits within a 60 40 split section or needs the full bench.
Safety
Fitting and Safety
A car seat on its own does not restrain your dog. The Highway Code's Rule 57 says dogs should be suitably restrained so they cannot distract the driver or get injured if you stop suddenly. It is not a criminal offence in itself, but GOV.UK notes that failing to follow the Highway Code can be used as evidence in court proceedings, for example to help establish careless driving.
Not every harness is suitable for this. An everyday walking harness is not necessarily strong enough to hold a medium dog safely under braking. Look for a harness designed for in car use, and pair it with the seat's tether or a seat belt loop rather than clipping a lead to a collar.
There is no UK legal requirement for pet car products to be crash tested. Before trusting a crash tested claim, check which organisation carried out the test, which standard was used, which exact model was tested, and whether documentation is available to view.
Comfort and Ventilation
Padded sides or bolsters give a medium dog a more contained feeling than a flat seat alone, and a mesh window or canopy panel keeps air moving on warmer journeys while giving your dog a view out.
Cleaning and Durability
Check the stitching around the anchor points, since this is where most wear happens. A removable, machine washable cover makes it far easier to deal with muddy paws and shedding fur.
Introducing Your Dog to a New Car Seat
Let your dog explore the seat at home first with a few treats nearby, rather than fitting it in the car and expecting them to settle straight away. Once they are comfortable climbing in and lying down, fit the seat in the car and attach the tether to their harness.

Common Questions About Medium Dog Car Seats
What is the best car seat for a medium sized dog?
It depends on your dog's weight, build and temperament. Calmer medium dogs often suit an elevated base or non elevated seat rather than a small dog style booster, since most boosters are only rated up to around 12 to 14kg. Always check the seat's exact weight limit and base dimensions against your dog before buying.
What makes a medium dog car seat safe?
Look for a stated weight limit that matches your dog, a non slip base, and secure attachment points such as headrest straps combined with a lower seat strap or seat belt loop. The seat should work alongside a harness, not replace one, since a car seat alone does not restrain your dog.
Can a medium dog car seat be both safe and comfortable?
Yes, but the two don't always come from the same feature. Padding, bolsters and a mesh window add comfort, while a wide base, reinforced anchor points and a proper harness add safety. A well designed seat combines both.
Are dog car seats legal in the UK?
There is no specific law naming dog car seats, but the Highway Code's Rule 57 says dogs should be suitably restrained in a vehicle. A car seat used with a harness or tether helps meet this. Not following it is not a criminal offence on its own, but it can be used as evidence in court if something goes wrong.
What should I look for in a well made medium dog car seat?
Check the stitching around the anchor points and straps, since this is where most wear happens. A removable, machine washable cover, a non slip base, and clear stated dimensions are signs of a well thought out design. If a seat also converts into a bed, check the padding holds its shape once unzipped.
Can a medium dog use a centre console car seat?
Usually not comfortably. Centre console seats are designed for the narrow space between the front seats, which suits small dogs and cats rather than medium breeds. A rear seat booster, elevated base seat, or non elevated bed style seat gives a medium dog more room.
Can a medium dog car seat double as a travel bed?
Some do. A few designs unzip flat or fold out so the padded base works as a dog bed once you reach your destination, useful for road trips or holidays. Check the product description specifically states this, since not every car seat is built to double up this way.
