A crate is one of the few pieces of dog equipment that solves several problems at once: toilet training, safe confinement when you cannot supervise, a settled place to sleep, and crate rest if your dog is ever injured. Get the size and type wrong and it solves none of them.

Size first — this decides everything
The rule is: your dog should be able to stand without ducking, turn around comfortably, and lie fully stretched on their side.
That is the ceiling, not the target. A crate much larger than that breaks toilet training, because a puppy will happily toilet in one end and sleep in the other. Dogs avoid soiling where they sleep — but only if where they sleep is the whole space.
Measure your dog:
- Length: nose to base of tail, then add two to four inches.
- Height: floor to the top of the head when sitting, then add two to four inches.
Buy for the adult size your dog will reach, and use a divider panel to shrink the usable space while they grow. Moving the divider forward every few weeks is far cheaper than buying three crates.
Wire crates
The default choice, and for good reason. Folding wire crates ventilate well, let the dog see out, come with dividers, collapse flat for storage, and have a removable tray that makes accidents survivable.
They are not the quietest option — bars rattle — and an anxious dog can rock one. A crate cover over three sides turns a wire crate into something much more den-like, which suits dogs who settle better when they cannot see the room.

Folding wire crate with a divider panel and a removable plastic tray, in a full range of sizes. The divider is the reason this works for a growing puppy — you buy the adult size once and reduce the space rather than replacing the crate.
Plastic travel crates
Solid-sided, airline-style carriers. More enclosed, warmer, and better for dogs who want to be hidden. They are also the only type that is genuinely safe for car travel and the only type accepted for air travel.
The downsides: harder to clean than a tray, poorer airflow in hot weather, and they do not fold.
Soft-sided crates
Fabric over a light frame. Light, quiet and easy to carry — good for a dog who is already reliably crate trained and travels to shows, sports or holiday lets.
Do not use one for a puppy, a chewer, or any dog left alone in it. A determined dog is through the mesh in minutes.
Furniture crates
Wooden end tables with a barred door. They look better in a living room and work perfectly well for a settled adult dog who uses the crate as a bed. They are not for puppies — wood absorbs urine, is chewable, and rarely comes with a divider.
What goes inside
Bedding: something washable and machine-dryable. Skip expensive beds until you know your dog does not shred bedding when alone. For a puppy, a folded towel or a flat vet-bed pad is more sensible.
Water: a clip-on bowl rather than a free-standing one, which will be tipped within the day. For short periods, a dog does not need water in the crate; for longer, they do.
Something to do: this is the difference between a dog who tolerates the crate and one who likes it. A stuffed rubber toy given only at crate time makes the crate the place good things happen.

A hollow rubber toy you can stuff with food and freeze. Reserve it exclusively for crate time and the crate becomes a destination rather than a punishment.
Where to put it
Somewhere the family is — a corner of the living room, or a quiet part of the kitchen. Not a garage, not a utility room behind a closed door, and not somewhere isolated from everyone. The point of a crate is a safe place to relax near the people; a crate in a distant room teaches a dog that going in means being abandoned.
Many people run two: one in the living area for daytime, one in the bedroom for night. For a new puppy, having the crate beside your bed for the first weeks makes night-time settling dramatically easier.
What a crate is not
It is not a solution to separation anxiety — for a truly anxious dog, confinement usually makes panic worse, and that needs a behaviour plan rather than a door. It is not a place to put a dog for hours as routine. And it is never a punishment; a crate a dog is sent to in anger stops being a refuge within a week.
Used properly, a crate is the room a dog chooses. Used as storage, it is a cage. The equipment is identical — the difference is entirely in how you introduce it.
