Size: the stand-turn-lie rule, applied strictly
The AKC’s crate sizing rule is that the dog should be able to stand without ducking, turn around comfortably, and lie down fully stretched. That is the whole specification, and on a small dog it is a smaller box than most people expect.
| Crate size | Typical dog |
|---|
| 22 in | Toy breeds up to roughly 10 lb |
| 24 in | Small dogs to about 20 lb |
| 30 in | Small-medium, roughly 20–35 lb |
Measure the dog rather than trusting a weight band: nose to base of tail, and floor to the top of the head sitting up. Add a couple of inches to each. Our crate size guide has the full method.
Buy the divider version if there is a puppy involved
A divider lets you buy the adult crate and shrink the usable area to puppy-appropriate, moving it out as the dog grows. For a small breed that is still worth doing — a 30-inch crate for a cocker puppy is a bathroom with a bed in it until the divider goes in.
The MidWest iCrate and the Amazon Basics both ship with one. Our puppy crate page covers the divider strategy in full.
Bar spacing: the small-crate safety issue
Check the stated wire spacing and look at the photograph. On a small crate you want tight spacing, and you especially want it on the door, where the frame and the latch create the widest gaps in the whole structure.
This is the one place we would not buy the cheapest option available from an unfamiliar brand. A crate is a box the dog is left in, and the failure mode is not inconvenient, it is dangerous.
Stop it moving on a hard floor
Light crates travel. A small dog turning around inside a 24-inch wire crate generates enough force to shift it an inch at a time across laminate, and over an afternoon that means a crate against the wall, or against a radiator.
Put it on a rug or interlocking foam mat. That adds friction, protects the floor from the feet, and cuts the noise the tray makes every time the dog moves — which is its own small improvement for a dog that startles easily.
Tray rattle is worse at this size
Every wire crate has a plastic tray, and every plastic tray rattles when a dog shifts. On a large crate with a heavy dog, the dog does not move much once settled. Small dogs reposition constantly, and the tray becomes a percussion instrument.
A crate pad over the tray largely solves it and makes the floor comfortable at the same time. Get a washable one — see our crate pad picks.
Where to put it
In the room the household is in. A crate in a spare room teaches a small dog that being crated means being separated from everyone, which is the opposite of the association you want. Corner rather than thoroughfare, away from a radiator, not in direct sun.
Small dogs also benefit disproportionately from partial covering. A crate cover or a towel over three sides turns a wire box into an enclosed den, and for a small dog in a room full of large moving humans that is a meaningful difference. Leave the front open and never cover a crate in warm weather.
Wire, plastic or soft, for a small dog
Wire is the default: best airflow, easiest to clean, foldable, and it takes a divider. Plastic feels more den-like and is the format most airlines require, but it is harder to clean and warmer. Soft crates are for travel with a dog that is already settled — see our soft crate roundup.
The KindTail PAWD is a genuine third option here: rigid panels rather than fabric, twelve pounds, and it folds to a four-inch slab, so it is easier to move between rooms than a wire crate — which matters more in the small sizes, where the crate might live in a bedroom at night and a kitchen by day.
What we would actually buy
For most small dogs: the MidWest iCrate in 24 or 30 inch, with the divider if there is a puppy, on a rug, with a washable pad. If the budget is the constraint, the Amazon Basics does the same job for less. If the crate has to move around the house daily or look less like a cage, the KindTail PAWD — provided your dog is inside its stated 15 to 25 lb range. And a small soft crate for trips, once the dog is genuinely happy in the crate at home.
