Stair gates and dog-proofing a British home
The short answer
- Our pick
- A tall, screw-fixed gate with no bar along the floor, put in the doorway of the one room your dog will actually live in. Which? says plainly that only screw-fix gates belong at the top of stairs, and the dog-gate makers say at least 40 inches of height for a medium or large dog.
- On a budget
- Skip the gate on the stairs and gate the room instead. A zooplus Savic Dog Barrier 2 in the 107cm height was £61.49 in October 2026, and the fixes that matter most (cables, bins, a clear floor) cost almost nothing.
- Don't buy
- A pressure-fit baby gate at the top of the stairs. It can give way under enough force, the bar across the floor is a trip hazard, and a dog that bounces off it once will learn what it takes.

Most advice on dog-proofing is a list of things to hide. Put the chocolate up high, tuck the cables away, buy a gate.
The gate is the only item on that list that costs real money, and it is the one people buy wrongly. They buy a baby gate, because the shop calls it a stair gate, and they fit it where a baby gate is meant to go. A dog is not a baby. A dog is lower, faster, heavier at speed and a good deal more interested in the thing on the other side.
What a stair gate is actually for
There are three jobs a gate can do, and they want different gates.
Keeping a puppy off the stairs. Battersea’s advice is short: “Baby gates are your friend - great for stairs or off-limit rooms,” and “Keep stairs off-limits for now - their growing joints need protection.”
Keeping a puppy out of rooms. PDSA recommends baby gates between rooms, and adds the part that matters for the dog: “your dog can still see you so they tend not to get worried about being left alone.”
Keeping a puppy in one room. This is the job most people forget. Dogs Trust suggests gates to separate a dog from you while it can still see you, as long as the dog stays relaxed. A gated room is the middle ground between a crate and the whole house, and it is covered in more detail in playpen or crate.
Notice that only the first job involves stairs. If you gate the doorway of the room the puppy lives in, the stairs are already out of reach, and you need one good gate instead of two.
Screw-fit or pressure-fit
This is the decision that has a right answer.
A pressure-fit gate is held in the opening by pressure at four points. No drills, no holes, and you can move it between doorways. That is its whole appeal, and for a dog it is also its limit. D for Dog, which sells dog gates, says pressure-fitted gates suit restricted access but “can give way under enough force”, and calls the bar across the base of an open pressure-fit gate “a dangerous trip hazard that you definitely don’t want on a staircase.”
A screw-fit gate is fixed into the wall or door frame with metal screws. Which? describes it as very strong and with no bottom rail. The price is holes in your walls when you take it down, and some assembly.
| Pressure-fit | Screw-fit | |
|---|---|---|
| Drilling | None | Yes, both sides |
| Floor bar when open | Usually | No |
| Holds against a bouncing dog | Poorly | Well |
| Top of stairs | No | Yes |
| Rental-friendly | Yes | Ask first |
| Best for | A doorway, a kitchen, a day trip | Stairs, a permanent room gate |
The rule from Which? is the one worth remembering: “You should only use screw-fix gates at the top of the stairs.” Gates there should also open towards the landing, not out over the flight.
If you rent and cannot drill, use pressure-fit in doorways only, keep it away from the stairs, and accept that you are managing the dog around it rather than trusting it.
How tall
Height is where dog gates part company from baby gates. Baby gates are built for a toddler who walks. D for Dog’s guidance is at least 40 inches (about 101cm) for medium or large dogs, and for small dogs that jump.
That number is easy to ignore when your puppy is the size of a loaf of bread. Don’t buy for the puppy you collect. Buy for the dog you will have in six months.
My Boxer, Bóris, went through a growth spurt between eight and ten months. Dogs do not stay the size you collected them, and a gate that only just works at ten weeks has a short life.
The same applies to width. Doorways in older British houses are not standard, and a gate that does not fit the gap is a gate you will not use. Measure the opening at the top, the middle and the bottom before ordering, and check what extensions the maker sells.
What it costs
Gates for dogs are not cheap, and the tall ones cost more than the baby-gate aisle suggests. These were the prices on zooplus in October 2026.
| Gate | Height | Price |
|---|---|---|
| Carlson Expandable Plastic Pet Gate (71-107cm wide) | 59cm | £36.59 |
| Trixie Mesh Dog Barrier (65-108cm wide) | 50cm | £51.69 |
| Savic Dog Barrier 2, Size 2 | 107cm | £61.49 |
| Savic Dog Barrier 2, Size 1 | 75cm | £66.59 |
| Savic 7cm extension (Size 2) | n/a | £14.79 |
Two things stand out. The 107cm Savic is cheaper than the 75cm one, so check the variant before you pay. And the cheap plastic gates stand at 59cm and 50cm. Those are fine for a sleepy toy breed and a waste of money for anything that can jump.
The Savic page says installation needs no drilling into walls or door frames and includes wall rings. It does not say whether it is screw-fit or pressure-fit, so read the fitting instructions before you put it at the top of anything. I would not use any gate at the top of a staircase unless the maker states it is rated for it and screws into the wall.
The jobs the gate does not do
The gate gets the attention. The cheaper jobs do more good.
Cables. PDSA suggests cable covers so a dog cannot nibble through live wires, and keeping wires out of reach where possible. A puppy teething on a phone charger is a vet bill and worse. This is also where teething toys earn their money: a puppy with something legal to chew is less interested in the sofa leg.
Bins and bags. The charities’ lists agree on the basics: chocolate, grapes and raisins, onions and anything sweetened with xylitol. Handbags and kitchen bins are how most of it gets eaten. A bin with a lid, and a hook for the bag.
Small things on the floor. PDSA’s list of things a dog mistakes for toys is shoes, children’s toys and TV remotes. Put them on a shelf or in a cupboard with a child-proof lock.
Slippery floors. Battersea suggests rugs or mats on slippery floors, and closing low windows and blocking balconies. A laminate hallway is a skating rink for a puppy, and a scrabbling start is a bad way to learn about the stairs.
The garden. PDSA says to check that fences and gates are secure, remove poisonous plants from where the dog can roam, and cover ponds. Do this before collection day, not after the first escape. A puppy that learns the fence has a gap tends to remember it.
For the full shopping list around all this, the puppy checklist sorts what to buy before collection from what can wait. Gates sit firmly in the “buy before” column only if you plan to use one.
Gate a room, not a staircase
Here is the contrarian bit. If you have the choice, I would not put a puppy anywhere near a gate on the stairs. I would put a screw-fixed gate in the doorway of the kitchen or the room with the easiest floor to clean, and I would shut the stairs out of the dog’s world altogether.
It solves more problems. Stairs stay out of reach, which Battersea wants anyway. The puppy can see you, which PDSA says reduces worry about being left. The room is easy to make safe because it is one room. And toilet training is simpler when the puppy has one set of floors to learn.
It also keeps the first night manageable. If you are planning one, the first night guide covers where the puppy sleeps, and a gated room is a sensible place to leave the door open to the crate.
Who should skip the gate
If you live in a flat with no stairs and a dog that stays where you put it, you may not need one. Closed doors do the job.
If your dog is an adult, calm and past chewing, a gate is a convenience, not a safety item. Don’t buy a £60 gate for a problem you don’t have.
And if your plan is to leave a dog behind a gate for a working day, the gate is not the answer. Blue Cross and PDSA both cap crate time at about three hours, and the Royal Kennel Club puts a puppy’s fair time alone at a couple of hours. A bigger enclosure does not change how long a puppy can be left.
What to do next
Decide whether the gate is replacing a crate or sitting alongside one. The crate size guide covers the sizing that matters if you are using both, and playpen or crate covers the choice itself.
Then walk the house at puppy height before collection day. Get down on your knees, and look at what a dog can reach. It takes ten minutes and finds more than a checklist.
Gate heights and fitting guidance are from Which?, D for Dog, Battersea and PDSA, with Dogs Trust and Blue Cross quoted for separation and crate-time limits, all checked October 2026. Prices were checked on zooplus.co.uk in October 2026 (rechecked 18 October; Carlson £36.69 → £36.59) and move often; fitting method for the Savic gate was not stated on the product page. Nothing here is veterinary advice — if your dog has eaten something it should not have, call your vet straight away.
