Before You Buy
Key Buying Factors
01
Portability
Look for foldable designs and lightweight materials. We found that wire crates with collapsible panels and carrying handles are easiest to transport.
02
Security
Ensure locking mechanisms are sturdy. Self-locking doors and reinforced corners prevent escapes, especially for anxious small dogs.
03
Size and Comfort
Measure your dog's height and length. The crate should allow standing and turning. For small breeds, 24-30 inch lengths work well.
04
Ease of Cleaning
Removable trays or washable mats simplify maintenance. We prefer metal or plastic bases that wipe down easily.
05
Durability
Check gauge of wire or thickness of plastic. Heavy-gauge steel withstands chewing and travel wear better than thin materials.
06
Assembly
Tool-free folding designs save time. Many products set up in under a minute, which we appreciated during testing.
Living With It
Care, Cost and Maintenance
Regular Cleaning
Wipe down surfaces with pet-safe disinfectant weekly. Remove and wash tray or mat to prevent odor and bacteria buildup.
Inspect Hardware
Check latches, hinges, and locking pins monthly for signs of wear. Replace any damaged parts immediately to prevent escapes.
Storage
When not in use, fold the crate or playpen flat and store in a dry area. Avoid stacking heavy items on top to maintain shape.
Pro tip
When using a crate in a hotel, add a portable door lock like the Guard Dog Security Blocklock for extra safety against escape.
