Quick Comparison

Quick answer

The best heavy duty dog crate for dogs under 20 lbs is the Petmate Sky Kennel Pet Carrier. It offers airline-approved strength, secure ventilation, and a sturdy build that withstands anxious chewers. For a more budget-friendly option, the MidWest iCrate Fold & Carry provides excellent durability with a double-door design and easy setup.

What to consider for Heavy Duty Dog Crate For Dogs Under 20 Lbs

When choosing a heavy duty crate for small dogs, focus on material thickness, door latch security, and ventilation. Small dogs can be surprisingly strong chewers, so look for welded wire or heavy-duty plastic with reinforced corners. Ensure the crate is easy to clean, as accidents happen. Also, consider portability and whether the crate folds flat for travel. Size is critical: the crate should be just large enough for the dog to stand, turn, and lie down, but not so large that it feels insecure.

What to look for in a cleaning or lawn product (urine, stain, odour or lawn-repair)

Choose a cleaner with genuine enzymatic action that breaks down urine and odour at the molecular level. Look for pet-safe ingredients once dry, and proven effectiveness on both stains and smells. For outdoor use, select a lawn-safe formulation that won’t harm grass or soil. Avoid products with ammonia, bleach, or harsh chemicals that can attract dogs back to the same spot or cause lawn damage.

How we chose these picks

  • Evaluated crate construction materials and durability ratings from manufacturer specs.
  • Reviewed customer feedback on security features like door locks and latch strength.
  • Considered size options specifically for dogs under 20 lbs.
  • Assessed ease of assembly, portability, and storage.
  • Checked for safety certifications such as airline approval or ASTM standards.
  • Compared price points to ensure value for money.
  • Consulted professional trainer recommendations for crate training.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Avoid ammonia-based cleaners: the smell mimics urine and can encourage re-soiling.
  • Do not use products not labelled pet-safe; some contain phenols or bleach that are toxic.
  • Skip harsh lawn chemicals like high-nitrogen fertilizers that can burn grass and harm pets if ingested.

Top 5 Picks

#1
Petmate Sky Kennel Pet Carrier
Best Overall

Petmate Sky Kennel Pet Carrier

View on Amazon

This crate is built like a tank with heavy-duty plastic and reinforced metal door. It's airline-approved, so you know it's secure. The ventilation slots are ample for small dogs. However, it's heavier than some wire crates, making it less portable for daily use.

#2
MidWest iCrate Fold & Carry Single Door & Double Door Collapsible Wire Dog Crate
Best Budget

MidWest iCrate Fold & Carry Single Door & Double Door Collapsible Wire Dog Crate

View on Amazon

Offers excellent value with durable wire construction and a secure slide-bolt latch. It folds flat for easy storage and includes a divider panel for growing pups. The main trade-off is that the wire can be bent by determined chewers over time.

#3
EliteField 3-Door Folding Soft Dog Crate
Best for Travel

EliteField 3-Door Folding Soft Dog Crate

View on Amazon

Lightweight and portable with a sturdy steel frame and mesh windows. It sets up in seconds and has three doors for easy access. However, it's not chew-proof and is best for calm dogs who don't try to escape.

#4
ProSelect Empire Dog Crate
Best Heavy-Duty

ProSelect Empire Dog Crate

View on Amazon

Made from heavy-gauge steel with a reinforced door and triple-lock latch system. It's designed for escape artists and aggressive chewers. The downside is it's quite heavy and expensive, but it's nearly indestructible.

Amazon Basics Foldable Metal Wire Dog Crate
Best Value

Amazon Basics Foldable Metal Wire Dog Crate

View on Amazon

A budget-friendly option with a sturdy wire frame, two doors, and a removable plastic tray. It's easy to assemble and clean. The limitation is that the latch is not as secure as more expensive models, and it may not hold up to persistent chewing.

Before You Buy

Key Buying Factors

01

Material and Build Quality

Look for heavy-gauge steel wire or high-impact plastic. Welded seams and reinforced corners add durability. Avoid thin wire that can be bent easily.

02

Door Security

A secure latch is crucial. Slide-bolt or double-lock mechanisms are best. Check that the door hinges are strong and the door fits flush without gaps.

03

Size and Fit

The crate should be just big enough for your dog to stand, turn, and lie down. For dogs under 20 lbs, typical sizes are 18 to 24 inches long. A divider panel is useful for puppies.

04

Portability and Storage

Consider if you need a crate that folds flat for travel or storage. Soft-sided crates are lightweight but less secure. Wire crates often fold easily.

05

Ventilation and Visibility

Good airflow is essential. Wire crates offer excellent ventilation. Plastic crates should have multiple vents. Some dogs prefer more visibility to reduce anxiety.

Living With It

Care, Cost and Maintenance

Cleaning the Crate

Remove the tray and wash with mild soap and water. For wire crates, wipe down the bars. Use a pet-safe disinfectant. Rinse thoroughly and dry before reassembling.

Maintaining the Latch

Periodically check the door latch for wear. Lubricate with a silicone spray if it becomes stiff. Replace any damaged parts immediately to prevent escapes.

Inspecting for Damage

Regularly examine the crate for bent wires, cracks, or sharp edges. Repair or replace if compromised. For plastic crates, check for stress fractures around the door.

Pro tip

Place a comfortable bed and a safe chew toy inside the crate to create a positive association. Never use the crate as punishment.

Frequently asked questions

How do enzyme cleaners work for pet stains?
Enzyme cleaners contain beneficial bacteria that produce enzymes to break down urine, feces, and vomit into harmless byproducts. The enzymes target specific organic compounds like urea and uric acid, eliminating odors at the source rather than just masking them. For best results, apply the cleaner to the stain, let it sit for 10 to 15 minutes (or as directed), then blot or rinse. Avoid using other cleaners beforehand, as they can interfere with the enzymes.
Are enzyme cleaners safe for pets?
Most enzyme cleaners are formulated to be safe for pets once dry. However, always check the label for pet-safe certification. Avoid products with added fragrances or harsh chemicals. Keep pets away from the area until it is completely dry to prevent ingestion. If your pet has sensitive skin or allergies, choose a hypoallergenic formula. When in doubt, consult your veterinarian.
How can I remove set-in urine odor from a crate?
For set-in odors, first clean the area with an enzyme cleaner specifically designed for pet stains. Saturate the stain and allow it to soak for 15 to 30 minutes. Blot up excess liquid, then let it air dry. For stubborn odors, repeat the process. If the crate is plastic, you can also soak it in a solution of water and enzyme cleaner. Avoid using steam cleaners, as heat can set the stain and odor.
What causes yellow spots on lawns from dog urine?
Yellow spots are caused by high concentrations of nitrogen and salts in dog urine. The nitrogen burns the grass, while salts dehydrate the roots. Female dogs tend to cause more spots because they squat and release a larger volume in one area. To prevent spots, dilute the urine by watering the lawn immediately after your dog urinates, or train your dog to use a designated area with gravel or mulch.
Can I use the same cleaner on carpets and hard floors?
Many enzyme cleaners are safe for both carpets and hard floors, but always check the label. For carpets, avoid over-wetting to prevent mold. For hard floors, ensure the cleaner is safe for the finish (e.g., wood, laminate). Some cleaners may leave a residue on hard floors, so follow with a damp mop if needed. Test in an inconspicuous area first.
How do I use cleaning products safely around my dog?
Always follow the manufacturer's instructions. Keep your dog away from the area until the cleaner is completely dry. Use products labeled pet-safe and avoid those with bleach, ammonia, or phenols. Store cleaners out of reach. If your dog ingests any cleaner, contact your veterinarian or a pet poison helpline immediately.
Can I use a steam cleaner on pet stains?
Steam cleaners are not recommended for pet stains because the heat can set the stain and odor, making them harder to remove. Additionally, steam may not penetrate deep enough to break down urine crystals. Stick to enzyme cleaners for best results. If you use a steam cleaner for general cleaning, ensure the stain is fully removed first.
What should I do if my dog keeps peeing in the same spot?
First, thoroughly clean the area with an enzyme cleaner to remove all traces of odor. Then, block access to the spot or place a different surface (like a rug or mat) over it. Increase bathroom breaks and reward your dog for eliminating outside. If the behavior continues, consult a veterinarian to rule out medical issues, or a certified trainer for behavioral help.
Are there any safety concerns with heavy duty crates?
Heavy duty crates are generally safe, but ensure proper size and ventilation. Remove collars or tags that could get caught. Check for sharp edges or loose parts. Never leave a dog in a crate with a broken latch. For plastic crates, ensure adequate airflow. Introduce the crate gradually to avoid anxiety. If your dog shows signs of distress, consult a professional.
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.
