Quick Comparison

Quick answer

The best heavy duty dog crate for crate training is the Gunner G1 Intermediate Crate for its unmatched crash-tested strength and secure locking system.

For extra-large breeds, the Frisco Heavy Duty Fold & Carry provides a spacious, sturdy design.

What to consider for Heavy Duty Dog Crate For Crate Training

When choosing a heavy duty dog crate for crate training, focus on durability, security, and comfort. The crate must be strong enough to withstand chewing or scratching from anxious dogs. Look for reinforced steel doors, heavy-duty latches, and welded seams. Proper sizing is critical: the dog should be able to stand, turn, and lie down comfortably. Ventilation is also important for airflow and temperature regulation. Consider the crate’s portability if you plan to travel with it. Finally, ensure the crate is easy to clean, as accidents can happen during training.

What to look for in a travel or containment product (crate, carrier, gate or car seat)

For any travel or containment product, prioritize safety and fit. The crate or carrier should be the correct size for your dog: not too tight, not too loose. Good ventilation is essential to prevent overheating. For car travel, look for crash-tested designs (e.g., Center for Pet Safety certified). For home use, escape-resistant construction with secure locks is key. Easy cleaning features, such as removable trays or washable pads, save time. Portability matters if you frequently move the crate. Avoid products with sharp edges or toxic materials.

How we chose these picks

  • Evaluated product specifications for durability, materials, and safety features.
  • Compared customer reviews for real-world feedback on sturdiness and escape resistance.
  • Checked for crash-test certifications from organizations like the Center for Pet Safety.
  • Considered size ranges to accommodate various dog breeds.
  • Assessed ease of assembly, cleaning, and portability.
  • Prioritized products with secure locking mechanisms and reinforced construction.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • A crate or carrier too small for the dog to stand, turn, and lie down in.
  • Unsecured carriers in a moving car; always use seat belts or crash-tested anchors.
  • Flimsy gates that a determined dog can push through or jump over.
  • Over-long crating; adult dogs should not be crated more than 8 hours at a time.

The Options

Types Explained

Wire Crates

Made of metal wire panels, often with a removable plastic tray. They provide good ventilation and visibility, and many fold flat for storage. They are generally lighter and more affordable.

Best for: Home use, crate training, and dogs that are not heavy chewers.

Plastic Crates

Molded plastic shells with a metal door and ventilation slots. They are more enclosed, providing a den-like feel, and are often airline-approved. They offer better impact resistance than wire crates.

Best for: Travel, airline transport, and dogs that prefer a cozy, dark space.

Heavy-Duty Metal Crates

Constructed from thick-gauge steel with reinforced welds and heavy-duty locks. They are extremely durable and escape-proof, but very heavy and expensive.

Best for: Strong, anxious, or escape-prone dogs, and for long-term containment.

Soft-Sided Carriers

Fabric carriers with mesh panels and a padded interior. They are lightweight and portable, but not suitable for heavy chewers or strong dogs. Some are crash-tested for car use.

Best for: Small dogs, air travel (if airline-approved), and short trips.

Top 5 Picks

#1
Best Overall

Gunner G1 Intermediate Crate

View on Amazon

The Gunner G1 is the gold standard for heavy duty crates, with a roto-molded construction that is virtually indestructible. It is crash-tested by the Center for Pet Safety, giving peace of mind during travel. The locking system is secure yet easy to use. However, it is heavy and expensive, making it less portable and budget-friendly.

Best for Large Dogs

Frisco Heavy Duty Fold & Carry Double Door Dog Crate

View on Amazon

This crate offers a spacious interior for large breeds, with a sturdy metal frame and reinforced doors. It folds flat for storage and includes a removable plastic pan for easy cleaning. The double doors provide flexibility in placement. One limitation is that the wire construction may not deter determined chewers as well as solid plastic or metal crates.

#3
MidWest Homes iCrate Double Door Dog Crate
Best Budget

MidWest Homes iCrate Double Door Dog Crate

View on Amazon

The iCrate is a reliable, affordable option with a durable wire frame and a secure slide-bolt latch. It includes a divider panel to adjust the space as your puppy grows, and the double doors offer convenience. The main trade-off is that it is not escape-proof for strong dogs who can bend wires or manipulate latches.

#4
Sleepypod Mobile Pet Bed
Best for Travel

Sleepypod Mobile Pet Bed

View on Amazon

This carrier is crash-tested and airline-approved, making it ideal for travel. It features a padded interior, ventilation panels, and a seat belt loop for car safety. The design is stylish and comfortable. However, it is not suitable for large dogs (max weight 15 lbs) and is less durable for heavy chewers.

#5
Petmate Sky Kennel
Best Escape-Proof

Petmate Sky Kennel

View on Amazon

The Sky Kennel is a heavy-duty plastic crate with wire door and ventilation slots, designed to be escape-resistant. It meets most airline requirements and has a secure locking system. The plastic construction is tough but can crack under extreme impact. It is also heavier than some wire crates, making it less portable.

Before You Buy

Key Buying Factors

01

Material and Construction

Heavy duty crates are typically made of reinforced steel, heavy-duty plastic, or roto-molded polymer. Steel wire crates are lighter but can be bent by strong dogs. Plastic and polymer crates are more impact-resistant but heavier. Look for welded seams and reinforced corners.

02

Locking Mechanism

Secure locks prevent escapes. Look for heavy-duty slide bolts, padlock loops, or locking clips. Some crates have double-latch systems for added security. Avoid simple twist latches that a clever dog can manipulate.

03

Size and Fit

Measure your dog's height (from paws to top of head) and length (from nose to base of tail). Add 2 to 4 inches for comfort. The crate should allow the dog to stand, turn, and lie down without touching the sides. Many crates come with divider panels for growing puppies.

04

Ventilation

Good airflow prevents overheating. Look for multiple ventilation windows or slots on all sides. Some crates have mesh panels for breathability. Avoid crates with limited openings, especially in hot climates.

05

Portability and Storage

If you travel frequently, consider a crate that folds flat or has wheels. Weight matters for airline travel. Some crates have handles or shoulder straps. Check if the crate is airline-approved if you plan to fly.

Living With It

Care, Cost and Maintenance

Cleaning

Remove the tray or pad and wash with mild soap and water. For wire crates, wipe down the frame. For plastic crates, use a pet-safe disinfectant. Avoid harsh chemicals that may irritate your dog. Dry thoroughly before reassembling.

Inspection and Maintenance

Regularly check for loose screws, bent wires, or cracked plastic. Tighten hardware as needed. Lubricate hinges and latches with a pet-safe lubricant to keep them functioning smoothly. Replace any damaged parts immediately.

Storage

When not in use, store the crate in a dry, cool place. Fold wire crates flat to save space. For plastic crates, keep them assembled or disassemble carefully to avoid warping. Cover to protect from dust.

Pro tip

During crate training, place a worn t-shirt or blanket with your scent inside the crate to help your dog feel more secure and reduce anxiety.

Frequently asked questions

How do I size a heavy duty dog crate for crate training?
Measure your dog's height from the top of the head to the floor, and length from nose to base of tail. Add 2 to 4 inches to each measurement. The crate should allow your dog to stand, turn, and lie down comfortably. For puppies, use a divider to adjust the space as they grow. A crate that is too large can encourage soiling, while one too small is uncomfortable.
Are heavy duty dog crates safe for car travel?
Yes, if they are crash-tested and properly secured. Look for crates certified by the Center for Pet Safety. Use seat belts or cargo anchors to prevent the crate from sliding. Never place an unsecured crate in the front seat. Soft-sided carriers are generally not crash-tested and should be used with caution.
What are airline rules for dog crates?
Most airlines require hard-sided plastic or metal crates that meet IATA standards. The crate must have ventilation on at least three sides, a leak-proof floor, and secure latches. The dog must be able to stand and turn. Soft-sided carriers are only allowed for small dogs in-cabin. Check with your airline for specific size and weight limits.
How long can a dog stay in a crate during training?
Puppies under 6 months should not be crated for more than 3 to 4 hours at a time. Adult dogs can handle up to 8 hours, but it should not be a daily routine. Crate training should include regular potty breaks and exercise. Over-crating can lead to anxiety and health issues.
What ventilation is needed in a heavy duty dog crate?
The crate should have ventilation openings on multiple sides to allow cross-flow of air. For plastic crates, look for slots or windows. Wire crates naturally have good airflow. In hot weather, ensure the crate is not in direct sunlight and consider adding a fan or cooling mat.
How can I make a crate escape-proof?
Choose a crate with heavy-duty metal construction and secure locks. Use padlocks or carabiners on the door latches. Ensure there are no gaps or weak points. For determined chewers, reinforce corners with metal plates. Avoid crates with plastic parts that can be chewed.
What is the difference between soft and hard carriers?
Soft carriers are made of fabric with mesh panels, lightweight and portable, but not chew-proof or crash-tested. Hard carriers (plastic or metal) are more durable and secure, often airline-approved. Soft carriers are best for small, calm dogs and short trips, while hard carriers suit larger or anxious dogs.
Can a heavy duty dog crate help with separation anxiety?
A secure crate can provide a safe den-like space that reduces anxiety for some dogs. However, it is not a cure. Proper crate training with positive reinforcement is essential. If anxiety persists, consult a veterinarian or a certified behaviorist. Never use the crate as punishment.
What safety concerns should I watch for with dog crates?
Ensure the crate has no sharp edges or protruding screws that could injure your dog. Check that the door latch is secure and cannot be accidentally opened. Avoid crates with toxic materials or lead paint. Never leave a collar on your dog while crated, as it can get caught. Monitor for signs of distress or overheating.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
