Why Choose a Small Dog Car Seat?
01
Sized properly for small breeds, not a medium dog design scaled down
02
Elevated styles raise your dog to window height for a better view
03
One defined, comfortable spot instead of sliding around the seat
04
Storage pockets keep leads, water and treats within easy reach
Which Type Suits Your Small Dog?
| Your dog | Best option |
|---|---|
| Gets anxious or travel sick, likes to see out of the window | Elevated booster seat |
| Calm, prefers to curl up and sleep | Flat car bed style seat |
| Growing puppy | Adjustable puppy seat, checked every few weeks |
| Needs a spot without full elevation | Seat with harness attachment |
| Nervous about being raised up and exposed | Flatter or enclosed option |
See booster seats in detail in our Dog Booster Car Seat collection, or flat styles in Dog Car Bed.
How to Measure Your Small Dog
Weight alone does not guarantee a good fit, since small dogs vary a lot in shape. Check these four measurements before you buy.
Weight, using scales, or weigh yourself holding your dog and subtract your own weight
Body length, from the base of the neck to the base of the tail
Seated height, floor to the top of the head while sitting
Chest size, around the widest part, just behind the front legs
Compare all four against the product's stated dimensions, not just the weight limit.
Breed, Weight and Puppy Growth
This range is generally positioned for small breeds up to around 10kg. 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.
Puppy tip: look for a puppy car seat with adjustable straps and growing room, since puppies can put on weight quickly. Check measurements again every four to six weeks while they are growing, rather than assuming the fit at eight weeks old will still be right at six months.
Vehicle Compatibility
Most small dog car seats sit on the rear seat, secured using headrest straps, a lower seat strap, or both. Before buying, 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
✓ Whether the seat suits a three door car, if that applies to you
✓ The manufacturer's fitting instructions for your specific model
Comfort, Car Sickness and Anxiety
Car sickness and anxiety are common reasons owners choose a small dog car seat over letting their dog travel loose on the seat. Some dogs may travel more comfortably when they can see outside, which some owners find helps with restlessness on longer journeys, though this varies from dog to dog. A memory foam or supportive cushioned base adds comfort, and reinforced side walls help a small dog feel contained rather than exposed on an open seat.
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 in a vehicle 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, which can carry fines and penalty points. Pair any small dog car seat with a dog car seat harness that clips into its attachment point, or a dog seat belt tether.
Before trusting a crash-tested claim, check for:
✓ The organisation that carried out the test
✓ The test standard or protocol used
✓ The exact model and weight range tested
✓ Whether a test report or certificate is available to view
Cleaning
A removable, machine washable cover makes it much easier to deal with shedding and the odd muddy paw. Check whether the cover can go in the wash on its own or needs to be wiped by hand, and let it dry fully before putting it back on the seat.

Common Questions About Small Dog Car Seats
What is the best car seat for a small dog?
It depends on your dog's weight, temperament and how they travel. An elevated booster suits anxious or travel sick dogs. A flatter seat with a harness attachment suits calmer dogs. Always check the individual product's weight limit against your dog.
What is the safest way to restrain a small dog?
A car seat alone is not a restraint. Pair it with a harness clipped into the seat's attachment point, or a seat belt tether, so your dog cannot move around or be thrown forward under braking.
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. Not following it is not a criminal offence on its own, but it can be used as evidence in court if something goes wrong.
Do small dogs benefit from a car seat?
Yes, for many small dogs. An elevated seat gives them a view out of the window, which some owners find helps with restlessness, and gives them one stable spot instead of sliding around.
What makes a small dog car seat safe?
A stated weight limit that matches your dog's measurements, a secure harness attachment point, headrest straps, and a non slip base. A washable cover matters for hygiene, not safety.
Is there a crash tested car seat for small dogs?
A few brands claim crash testing, but there is no UK legal requirement for this, and independent testing is limited. Check the testing organisation, standard, and exact model tested, rather than trusting a general claim.
