Best dog crate: how to size it and which type to buy
Most people buy the wrong size, which is why the crate gets refused. Sizing is the decision; the material is secondary.

Sizing, which is where it goes wrong
A crate must let the dog stand without ducking, turn around, and lie flat on its side. Measure your dog standing, then add 2–4 inches to both length and height. Buy for the adult if you have a puppy, and use a divider panel to shrink the usable area while it's small — this also helps house-training.
| Adult weight | Crate length | Typical use |
|---|---|---|
| Under 15 lb | 24 in | Sleeping, travel |
| 15–40 lb | 30–36 in | Most medium breeds |
| 40–70 lb | 36–42 in | Labs, shepherds |
| 70 lb+ | 48 in | Large and giant breeds |
Wire, plastic, or soft-sided
Wire with a divider is the best default for home: airflow, visibility, and you can see the dog. Plastic airline crates are for travel and for dogs that seem to feel exposed. Soft-sided crates are for travel with a calm dog only — a chewer will destroy one in an hour.
Crate training, briefly
- Leave the crate open with bedding inside for two days. Drop treats in, don't close the door.
- Feed meals in the crate, door open, then closed for the length of the meal.
- Build to two minutes, then five, then fifteen. Always release before the dog protests.
- Never open the door while the dog is whining — that teaches whining works. Wait for a pause.
Safety rules people skip
Remove collars in the crate. A tag or buckle can catch between wire bars and strangle a dog. This is a documented cause of crate deaths and it costs nothing to prevent.
Questions people ask
What size crate does my dog need?
Measure the dog standing: length from nose to base of tail, plus 2–4 inches, and height from floor to top of head plus 2–4 inches. Most medium dogs need a 36-inch crate; large breeds 42 to 48 inches. Buy for adult size with a divider panel if you have a puppy.
Is a wire or plastic crate better?
Wire for home, because airflow and visibility help most dogs settle. Plastic (airline-style) for travel and for dogs that feel exposed in wire. Neither is better in the abstract.
Should a crate be covered?
Often yes — a blanket over two or three sides creates a den effect that helps anxious dogs settle. Always leave the door side open to air and never cover a crate in warm weather.
How long can a dog stay in a crate?
As a rule of thumb, puppies can hold their bladder roughly one hour per month of age, up to about four hours. Adult dogs should not be crated longer than four to six hours at a stretch.
Is crating cruel?
Not when the crate is properly sized, introduced with rewards, and used for rest rather than punishment. It becomes harmful when it is undersized, used for long confinement, or the dog is forced in. Never use a crate as discipline.
