Dog Crates for Cold Weather: Insulation Checks

When cold weather protection matters

A dog crate does more than contain a dog. It can also create a small, sheltered space that holds body heat. In cold weather, that matters most for short-coated breeds, puppies, senior dogs, and dogs that have trouble regulating their temperature. The ASPCA's housing guidance says a dog needs a warm, quiet place to rest, away from drafts and off the floor, and a warm, dry, covered shelter if the dog spends time outdoors.

If the room is drafty or the floor is cold, an open wire crate may let too much heat escape. A plastic kennel or a covered crate can reduce that heat loss. Before choosing, consider your dog's coat, age, health, and where the crate will sit. For more on crate types, see dog crate materials comparison.

Plastic crates versus covered crates

Plastic crates have solid side and back walls, a molded base, and a door at the front. That enclosed shape blocks drafts from three sides and creates a cave-like space. Covered crates start with an open wire frame and add a fabric cover over most of the panels. Both approaches can keep a dog warmer, but they work differently.

A plastic kennel is the better choice when you need a self-contained shelter, such as in a car, an enclosed porch, or an outdoor building. A covered wire crate can work well indoors when you want airflow and visibility but still need to cut down on drafts. If you choose a cover, it should fit closely without sagging and should never block all openings. For fitted options, see best plastic kennel dog crates or best metal dog crates.

Insulation checks before cold weather

Run through these checks before you rely on any crate for cold weather. The goal is to keep the space warm without turning it into a sealed box. See the dog crate cover guide for more cover details.

• Draft check: place the crate away from windows, exterior doors, and heating vents that blow directly on it.
• Cover check: a cover should wrap around the sides and top, leaving at least one vented opening for fresh air.
• Floor check: raise the crate off a cold floor or add a pad under the tray; the dog should not sleep directly on a cold surface.
• Bedding check: use a washable blanket or pillow and clean it often, as recommended by the ASPCA.
• Fit check: the crate should be large enough for the dog to stand, turn, and lie down, but not so large that body heat is wasted.

Keep ventilation open

A warm crate is not a sealed crate. Plastic and covered crates reduce airflow, so you need to check the vents. Most plastic kennels have molded vents near the top and sides; keep them clear of bedding and covers. A covered wire crate should have at least one side uncovered, usually the front door, so air can move through.

Dogs with short noses, older dogs, and dogs with breathing issues may need extra airflow. If you are not sure whether your dog can breathe comfortably inside a covered crate, leave more of the cover off or choose a plastic kennel with larger vent openings. See the dog crate ventilation guide and the crate safety checklist for more.

Bedding and crate location

The ASPCA suggests a clean blanket or pillow inside a training crate or dog bed and washing bedding often. In cold weather, a thicker washable pad can add insulation between the dog and the floor. Avoid loose fabrics that a puppy or chewer can pull through the bars and shred.

Location also affects warmth. Keep the crate in the warmest part of the room, away from cold exterior walls and drafts. If the floor is tile, concrete, or laminate, place a rug or mat under the crate.

When to switch to a plastic or covered crate

If your dog is reluctant to settle, curls into a tight ball, or shivers in a wire crate, a plastic or covered crate may help. The change can also help anxious dogs because a covered, den-like space can feel more secure. If your dog has separation anxiety, however, covering the crate too much can make confinement feel more isolating; check the dog crate for anxious dogs guide.

For outdoor use, a plastic kennel is usually the more practical cold-weather crate because it provides a windbreak and a dry, covered shelter. If you take the crate into a vehicle or across state lines, the USDA pet travel page explains that a USDA-accredited veterinarian can help with destination requirements.

What to pick for your use

Questions

Is a plastic crate warmer than a wire crate?

Generally, yes. A plastic crate has solid walls that block drafts and trap body heat. A wire crate allows more airflow, which is useful in warm weather but can make a dog colder in winter. If you prefer wire, a fitted cover can add warmth.

Can I put a blanket over my dog's crate in cold weather?

Yes. A fitted crate cover can reduce drafts and help hold body heat, but it should never block all openings. Leave at least one vented side open.

Should I use a heated pad inside the crate?

Only if you follow the product's instructions and give your dog room to move away. A covered crate can get too warm, so check the dog and the bedding often. When in doubt, ask your veterinarian, as the CDC recommends talking to a vet about the right care for your dog.

What should I check before using a covered crate in winter?

Check the cover fit, vent openings, floor insulation, and bedding. Make sure the cover does not sag into the crate, keep one side open for air, place the crate off a cold floor, and use washable bedding. See the dog crate safety checklist.

Can a crate keep a dog warm enough outdoors?

A plastic kennel with solid walls and a dry, covered roof can act as a windbreak, but it is not a substitute for bringing a dog inside during extreme cold. The ASPCA says a dog needs a warm, dry, covered shelter when it is cold. Use the crate as one part of a safe winter setup and check on your dog often.
