How to Choose an Indoor Dog Crate
An indoor crate is one of the most useful pieces of equipment you can own, but only if you buy the right size and type and use it the right way. Get those two things wrong and you either waste money on a crate your dog outgrows in a month, or you create a dog that hates being confined. This guide walks through how to size a crate to your dog, how the main crate types differ, which door and divider options actually matter, how to think about escape-proofing, and, just as important, the welfare rules that keep a crate a good thing rather than a punishment.
Everything below is drawn from aggregated verified owner reviews and manufacturer specifications, not hands-on lab testing. Sizes, breeds and weights are guides. Measure your own dog before you buy.
Step 1, Measure your dog, then add a few inches
The most common crate mistake is buying by breed name instead of by measurement. Two dogs of the same breed can differ by ten pounds and several inches. Take two measurements with a tape:
- Length: from the tip of the nose to the base of the tail (where the tail meets the body, not the tip). Add roughly 2 to 4 inches.
- Height: from the floor to the top of the head when the dog is sitting up, or to the tips of the ears if it is a naturally alert, upright breed. Add 2 to 4 inches.
Step 2, Choose the crate type
Wire (folding) crates are the default for indoor use and cover most of the crates in this hub. They are airy, let the dog see out, fold flat for storage, and usually come with a slide-out plastic tray for easy cleaning. Most also accept a divider. The downsides are that bare wire is cold and hard without a pad, and the standard single-clip doors are not built for determined escape artists.
Plastic (airline-style) kennels, like the Petmate Vari Kennel, have a hard enclosed shell with a grille door. The enclosed sides give a more den-like feel that calms some dogs, and the rigid shell is what you need for car travel or flying. They do not fold, they offer less airflow and visibility, and they are less convenient as an everyday house crate.
Heavy-duty crates use thicker gauge steel or welded aluminium and stronger latches. They are the answer for powerful breeds, chewers, and dogs that work at the door. They cost more, weigh a lot, and rarely fold neatly, so only buy this class if a standard wire crate genuinely is not holding your dog. In this hub, a heavier-gauge 48-inch wire crate with slide-bolt latches bridges the gap for large or mildly determined dogs without jumping to a full escape-proof kennel.
Soft-sided crates are lightweight fabric-and-mesh crates for travel and calm, crate-trained dogs. They are not containment for a puppy or any dog that scratches or chews, so treat them as a travel convenience, not a training tool.
Step 3, Single door or double door
A single-door crate is simpler and usually cheaper, but it dictates how you can position the crate, because the door has to face out into the room. A double-door crate (typically a front and a side door) is far more flexible: you can tuck it into a corner or against furniture and still get the dog in and out easily. If you are unsure where the crate will live long term, double door is the safer choice.
Step 4, The divider is what makes puppy crates work
If you are buying for a puppy, prioritise a crate that includes a divider panel. Puppies need a crate sized to their current body, not their adult body, or house-training falls apart. A divider lets you buy one full-size crate now and simply move the panel outward as the puppy grows. It is the single feature that saves the most money and frustration, which is why several picks in this hub are chosen specifically for including one.
Step 5, Think honestly about escape-proofing
Be realistic about your dog. A calm adult needs nothing special. A dog that paws, nudges or leans on doors benefits from slide-bolt latches rather than single spring clips. A dog with genuine, injury-risk escape behaviour driven by separation anxiety needs a purpose-built heavy-duty kennel, and also needs a behaviour plan, because no crate alone fixes panic. Do not try to out-build a truly distressed dog with a bigger padlock. Address the anxiety with a trainer or vet at the same time.
A note on welfare, a crate is a den, never a punishment
Used correctly, a crate taps into a dog's natural instinct to seek out a small, safe den. Used badly, it becomes a cage the dog dreads. The rules that keep it positive are simple and non-negotiable:
- Introduce it slowly and positively. Feed meals in it, toss treats inside, leave the door open at first. The dog should choose to go in.
- Never use the crate as punishment. If the crate becomes where bad things happen, the dog will resist it forever.
- Do not use it for all-day confinement. A crate is for sleeping, short settles, house-training and travel, not eight-hour storage. Puppies in particular can only hold themselves for a few hours. As a rough guide, a puppy should not be crated for many more hours than its age in months, and no adult dog should be crated all day every day.
- Make it comfortable. Add a washable pad or mat over bare wire, and keep it somewhere the dog can still feel part of the household.
