Sizing & fit guide

Measure length from the nose to the base of the tail while your dog is standing, then add 2–4 inches for comfort. Measure height from floor to the tops of the ears when alert and allow at least 2 inches of headroom. If your dog is between sizes—or still growing—choose the larger crate so they can turn around and stretch out fully.

For puppies, size up and use a bolster bed to create a smaller “sleep zone” at first, then remove the bolster as they grow.

Build & materials

The powder-coated aluminum panels give this crate a sturdy, furniture-like feel without the harsh look of wire. Edges are tidy, the latch seats confidently, and the smooth coating resists hair and fingerprints. Color options make it easier to match your home or vehicle; availability varies by size.

Setup & portability

This crate folds completely flat for storage or travel. The first assembly takes a few minutes while you learn the hinge paths and locking tabs; after that, setup and takedown become quick and repeatable. Once locked, the crate feels stable on hard floors and low-pile rugs. It’s lighter than many steel “heavy-duty” crates, though you’ll still want a deliberate lift when moving the Large size.

Cleaning & care

Daily upkeep

Finish each day with a quick wipe of the latch, door frame, and corners using a damp microfiber cloth and a drop of mild, pH-neutral dish soap. The slick powder coat releases fur easily, so most hair comes off in a single pass. Dry the latch and hinge area to prevent dust from caking there between cleanings.

Weekly deep clean

Once a week, remove the pad and blankets so you can reach every surface. Vacuum the interior with a crevice tool to pull hair from seams and the door track. Wipe the panels with warm water and a small amount of mild soap, then go over everything again with clean water to remove residue. Leave the door open to air-dry fully before replacing the pad, and give the locking tabs and hinges a quick check while you’re there.

After accidents

Blot liquids immediately, then saturate the area with an enzyme-based cleaner and allow 5–10 minutes of dwell time to break down odor-causing proteins. Wipe clean, follow with a water-only pass to remove any cleaner left behind, and dry thoroughly—especially around seams where moisture can linger. Wash the pad per its care label and treat the edges with the same enzyme cleaner if needed.

Odor control & prevention

Use a washable, full-coverage pad to catch hair and protect the floor panel. For routine odor neutralizing, a light rinse of one part white vinegar to ten parts water is safe for aluminum; always wipe again with plain water so no vinegar scent remains. Keep the crate in a ventilated spot and leave the door open for a few minutes after cleaning to help everything dry.

What to avoid

Skip abrasive powders and scouring pads that can scratch the powder coat. Avoid bleach and ammonia-based cleaners; they can discolor the finish and make odors more pronounced. If a hinge squeaks after a wash, a tiny drop of silicone-safe lubricant on the hinge pin will quiet it—just wipe off any excess so curious noses don’t find it.

How it compares

Versus wire crates: The aluminum build looks cleaner, resists bending, and doesn’t rattle as much. It still folds flat like wire, but feels sturdier once set up. Wire can be lighter and cheaper in smaller sizes; aluminum wins on durability and presentation.

Versus soft crates: Soft crates are light and quick to carry but can absorb odors and aren’t ideal for determined chewers. The Kennel Boss is hard-sided, non-absorbent, and more secure, with the trade-off of extra weight and a higher price.

Pros & cons

• Pros: Solid powder-coated aluminum; fully collapsible; tidy, modern look; multiple colors across sizes; smoother and quieter than typical wire once assembled.
• Cons: Heavier than soft crates; first setup has a short learning curve; Large only in Black/Gray.

FAQs

Does it come with a pad? Pads are typically sold separately. Choose a full-coverage, washable bed or mat for comfort and easier cleanup.

Good for puppies? Yes. Measure current size, consider sizing up, and use a bolster bed to create a smaller sleep zone until they grow into the full crate.

Chew-proof? Aluminum panels are far tougher than fabric, but no crate is completely chew-proof for every dog. Supervise early sessions and include appropriate chew toys.

Airline travel? Requirements vary by airline and route. Always confirm current rules for dimensions, ventilation, and hardware before you fly.

Final verdict

If you want a crate that looks sharp in the living room, stands up to daily use, and still folds flat when you need the space, the K9 Kennel Boss is an easy recommendation. Pick the size that matches your dog’s measurements, choose a color you like, add a washable pad, and you’re set.
