Metal Dog Crates: Pros and Cons
Metal wire crates are the standard choice for home training and long-term containment. Their open construction lets air circulate freely, which matters a lot for dogs with thick coats or homes without air conditioning. The wire design also gives your dog a full view of the room, which helps social dogs feel included rather than isolated.
Most metal crates fold flat in seconds, making them practical for owners who need to store or transport the crate occasionally. They also accept a wide range of accessories, including divider panels, plastic trays, and fabric covers, so one crate can adapt as your dog grows or as your setup changes.
Pros:
- Superior airflow keeps dogs cool in warm rooms or climates.
- Extremely difficult to chew, scratch, or bend through.
- Folds flat for storage or moving between rooms.
- Easily accessorized with dividers, trays, and covers.
- Holds up well across multiple dogs over its lifespan.
Cons:
- Bulkier and heavier to carry or reposition.
- Rarely accepted for airline cargo travel.
- Open sides can feel exposed to shy or nervous dogs.
- Wire edges may need padding for large, active breeds.
Plastic Dog Crates: Pros and Cons
Plastic crates mimic the shape and feel of a natural den, which many dogs find calming by instinct. Their solid walls block drafts and reduce visual stimulation from outside the crate, which is one reason they’re the standard choice for air travel and long car rides.
Because plastic crates are lighter and often come with a top handle, they’re easier for one person to carry, load into a vehicle, or move between locations. The trade-off is that most models don’t fold flat, so they take up more space in storage even though they weigh less overall.
Pros:
- Lightweight design, easy for one person to carry.
- Enclosed shape feels secure to anxious or shy dogs.
- Meets most airline IATA cargo requirements.
- Blocks drafts, useful in cooler climates or rooms.
- Generally more affordable upfront.
Cons:
- Less ventilation than open wire designs.
- Determined chewers can crack corners and latches over time.
- Bulkier to store since it doesn’t fold flat.
- Limited visibility can frustrate social, outgoing dogs.
- Seams and vents need regular deep cleaning.
Which Crate Suits Your Dog?
The right choice depends more on your dog’s temperament than on any spec sheet. A confident, social dog usually prefers seeing its surroundings and interacting visually with the household. A nervous, noise-sensitive, or newly adopted dog often settles faster in a smaller, enclosed space that limits stimulation.
Use this quick reference to match crate type to dog personality:
| Dog Type | Better Crate Choice | Why |
| Social, confident dogs | Metal | Wants visibility and airflow |
| Anxious or shy dogs | Plastic | Enclosed space feels secure |
| Heavy chewers | Metal | Resists damage long-term |
| Frequent travelers | Plastic | Airline and car-ready |
| Puppies under 6 months | Plastic | Den-like comfort for sleep training |
| Large or giant breeds | Metal | Stronger frame under weight |
Do Puppies Do Better in Metal or Plastic?
Puppies generally settle faster in plastic crates during their first few months. The compact, enclosed shape mimics a den and helps young dogs sleep through the night without feeling overwhelmed by an open view of the room. Many breeders and trainers recommend plastic for the earliest crate-training stage specifically for this reason.
As puppies grow and enter the teething phase, chewing intensifies and often targets the crate itself. This is usually when owners transition to a metal crate with an adjustable divider panel, since it resists chew marks and grows with the puppy instead of needing full replacement.
Puppy crate-training tips:
- Start with a size that fits your puppy now, not their adult size.
- Use a divider panel in a metal crate to prevent them from associating one end with sleeping and the other with bathroom use.
- Keep initial crate sessions short and always paired with positive reinforcement.
- Switch to metal once teething becomes aggressive, typically around 4 to 6 months.
Can a Plastic Crate Survive a Determined Chewer?
Plastic can handle occasional nipping or light scratching without issue, but a persistent chewer will eventually wear through corners, door latches, and vent edges. Once the plastic cracks, it can create sharp edges that pose a real safety risk to your dog’s mouth and paws.
If your dog has a documented chewing habit, metal is the safer long-term investment. It’s essentially chew-proof and doesn’t develop weak points from repeated gnawing at the same location, unlike plastic, which wears thinner each time.
Do Anxious Dogs Settle Faster in an Enclosed Crate?
Yes, in most cases. Solid plastic walls limit visual stimulation, which reduces reactivity to passing people, other pets, or street noise outside a window. This lower-stimulation environment often helps anxious dogs relax faster than an open wire design would.
That said, a metal crate can be adapted for anxious dogs with a few simple adjustments, which makes it a flexible option even for nervous temperaments.
Tips for anxious dogs in either crate type:
- Add a breathable cover over a metal crate to mimic a den-like enclosure.
- Place a worn t-shirt with your scent inside for comfort.
- Position the crate in a quiet, low-traffic corner of the home.
- Never use the crate as a form of punishment or timeout.
- Pair crate time with calm activities like a chew toy or puzzle feeder.
What Holds Up for Large and Giant Breeds?
Large and giant breeds put considerably more stress on a crate through sheer size, strength, and body weight leaning against the walls. Metal crates generally perform better here because their steel frames resist bending, warping, and structural fatigue over years of use.
Plastic crates rated for large breeds do exist, but it’s essential to check the maximum weight capacity before buying. A crate that’s undersized or under-rated for your dog’s weight will crack sooner and won’t withstand a full-grown dog pushing against the walls repeatedly.
Traveling With a Crate: Car, Airline, and Ferry Use
Plastic crates are the clear winner for air travel. Airlines almost universally require hard-sided plastic carriers that meet IATA Live Animal Regulations, and most wire crates won’t be accepted for cargo transport at all.
For car trips and ferry crossings, either style can work well, but plastic tends to secure more easily and shifts less during sudden braking. Metal crates are better suited to stationary use at home or in a stable vehicle setup, such as a van conversion or SUV with a dedicated crate area.
Travel crate checklist:
- Confirm your airline’s specific size and ventilation requirements before booking.
- Secure the crate with a seatbelt or cargo strap during car travel.
- Add absorbent bedding for longer trips.
- Label the crate with your contact information for flights.
How Easy Is Each Crate to Clean?
Metal crates wipe down quickly since there are no seams where waste, fur, or odor can collect. A hose rinse or damp cloth handles most everyday messes in just a few minutes, making metal a strong choice for multi-dog households.
Plastic crates need slightly more attention. Door hinges, vents, and molded seams can trap hair and odor over time, so plan on a deeper scrub with pet-safe cleaner every few weeks to keep things fresh.
How Long Does Each Type Actually Last?
Metal crates typically last 8 to 10 years or more with basic care, since steel doesn’t degrade from UV exposure or minor impacts the way plastic does. Many owners use the same wire crate across two or three dogs over its lifetime.
Plastic crates average 4 to 6 years of solid use under normal conditions. Prolonged UV exposure can make the plastic brittle, and repeated door slamming gradually weakens the latch mechanism, which is often the first part to fail.
Which Is Better Value in the UK?
Plastic crates usually cost less upfront, which makes them appealing for first-time owners or puppy parents who aren’t sure yet what their long-term needs will be. Metal crates cost more initially but often work out cheaper per year of use, given their significantly longer lifespan.
Value-buying tips:
- Buy one size up with a divider panel to avoid repurchasing as your puppy grows.
- Look for rust-resistant or powder-coated finishes on metal crates if you live in a humid climate.
- Choose BPA-free plastic construction for safety and long-term durability.
- Compare cost-per-year rather than sticker price alone when deciding between the two.
Choosing between a metal or plastic dog crate comes down to your dog’s size, behaviour, and lifestyle. Aosom offers options designed to suit different needs, with metal crates providing better durability, airflow, and chew resistance for home use, while plastic crates offer a secure, enclosed feel and easier portability for travel. Consider your dog’s specific needs to find the crate that provides the best balance of comfort, safety, and practicality.
FAQs
1. Can you put a bed in a metal or plastic dog crate?
Yes, both crate types can accommodate a suitable dog bed or mat. Choose bedding that fits the floor without leaving large gaps around the edges. For puppies, washable and easy-to-clean bedding can be especially practical.
2. Should a dog crate have a divider?
A divider can be useful when a puppy is expected to grow significantly. It lets you increase the available space gradually without buying another crate. The crate should still provide enough room for the dog to stand, turn around and lie down comfortably.
3. Where should I put my dog's crate at home?
Place the crate somewhere your dog can rest without being isolated from the household. Avoid areas with excessive heat, cold drafts or constant foot traffic. A calm corner of a living room or bedroom often works well.
