Overview
['This K9 Kennel Boss crate is a collapsible aluminum kennel built for large dogs, with a single door and included side rails and knurled bolts for assembly. Aluminum construction keeps it lighter than steel crates of a similar size while still being marketed as heavy duty.', "At 41.6 by 29.7 by 33.9 inches and 47 pounds, it's sized for large breeds and folds down for transport. The manufacturer backs it with a limited lifetime warranty against manufacturing defects, though that warranty doesn't cover damage caused by the dog itself.", 'Priced at $714.99, this sits well above typical wire and soft-sided crates in this category. With 213 reviews averaging 4.1 stars, it has a smaller review base than mass-market crates, consistent with a niche, higher-end product aimed at serious travelers or working dog owners.']

Performance notes
The aluminum frame with side rails and knurled bolt assembly is built for durability and repeated setup and breakdown rather than a permanent home fixture, which fits the crate's positioning for travel or working dog use. At 47 pounds it's still substantial to carry despite being lighter than a comparable steel crate.
What buyers say
With 213 reviews and a 4.1 star average, this crate has a smaller and slightly more mixed sentiment than budget wire crates in this category, which may reflect the higher price point setting steeper expectations for buyers.
It's a limited lifetime warranty against manufacturing defects, but it specifically does not cover any damage the dog causes to the crate.
Is aluminum sturdy enough for a large dog?
The manufacturer markets it as a heavy duty design despite using lighter aluminum instead of steel, aiming to combine durability with easier portability for large breeds.
How heavy is this crate?
It weighs 47 pounds and measures 41.6 by 29.7 by 33.9 inches, so it's sized for large dogs but still substantial to move without help.
