The Best Heavy-Duty Dog Crates
Almost every premium crate here carries a lifetime warranty that specifically excludes your dog destroying it. One does not. That is the whole story.
We went and read the warranty on every heavy-duty crate we could verify, and found something genuinely absurd.
These crates are sold to contain destructive dogs. And then the warranty excludes the destruction.
- Gunner — lifetime warranty, and: “The manufacturer’s warranty does not extend to cover destruction done to the product by the pet.”
- Lucky Duck — lifetime warranty, excluding “Pet related wear and tear including chewing and scratching.”
- ProSelect Empire — 1 year, and “Does not include breakage or damage caused by user or dog” — on a cage advertised “for powerful dogs that are able to claw or chew their way out of other cages.”
- Diggs Revol — 1 year, excluding “Damage caused by dogs who are not crate-trained or who chew on the product.”
- Impact (Stationary and Collapsible) — excludes “dog damage.”
There is exactly one exception on the entire market, and it is our top pick: the Impact High Anxiety crate, which carries a Lifetime Dog Damage Guarantee — in Impact’s own words, “If your dog breaks it, we’ll replace it.” Note the carve-out even here: that guarantee applies onlyto the High Anxiety line, not to Impact’s Collapsible or Stationary crates.
Gunner, meanwhile, tacitly concedes the whole argument by selling a separate steel “Chew Kit” — laser-cut, powder-coated steel covers — as an accessory for high-drive dogs. If the kennel could not be chewed, it would not need armour.
The steel specs, and who will not publish them
ProSelect Empire is the one brand here that gives you a real number: 20-gauge steel reinforced by 1/2 in diameter steel tubes, on a 3/4 in tube frame, with dual door latches. You can evaluate that. You can compare it.
MidWest markets the Ultima Pro as “professional-gauge, heavy duty steel construction” and then declines to publish an actual gauge anywhere. “Professional-gauge” is not a unit of measurement. It is a word that sounds like one.
Diggs will not publish a steel gauge either. Nor will SMONTER. Nor, for that matter, will Impact publish an aluminum gauge.
Latches are where crates are actually lost
A determined dog does not usually break out through a panel. It works the door.
- Slide bolts (MidWest, SMONTER) are the easiest to defeat — a dog with a nose and patience will work one open. This is the single most common escape.
- Dual latches (ProSelect Empire) mean two independent points to defeat.
- Two-step latches (Diggs Revol) require a sequence, which a paw cannot replicate. This is genuinely clever engineering.
- Paddle latches with a key lock plus backup latches (Gunner) are the most secure design here.

The picks, ranked
1. Impact High Anxiety Crate
Durability score 91/100Best for: The genuine escape artist — and the only warranty that pays out when a dog wins
The only heavy-duty crate whose maker will stand behind it when the dog wins — which, in a category built on excluding exactly that, is the whole argument.
- Material
- Powder-coated aluminum
- Warranty
- Lifetime Dog Damage Guarantee — 'If your dog breaks it, we'll replace it'
- Warranty scope
- High Anxiety crates ONLY — not the Collapsible or Stationary models
- Aluminum gauge
- Not published for this model
Pros
- This is the only crate we found, at any price, whose standard warranty actually covers your dog destroying it
- Every other heavy-duty brand — Gunner, Lucky Duck, ProSelect, Diggs, and even Impact's own other crates — excludes dog damage
- Aluminum, powder-coated, built for dogs that defeat everything else
Cons
- The most expensive crate here by a wide margin
- The Dog Damage Guarantee applies ONLY to the High Anxiety line. Buy the Collapsible instead and you lose it
- Heavy and not genuinely portable
- Impact does not publish the aluminum gauge
How we assessed it: on published materials, hardware specs and construction — not long-term chew-tested. We say so because it is true, and because a claim we cannot back is worth nothing to you.

2. ProSelect Empire Dog Cage
Durability score 73/100Best for: Raw steel strength per dollar
The most steel for the money and the most honest spec sheet in the category — sold with a warranty that excludes the exact thing you are buying it for.
- Steel
- 20-gauge steel reinforced by 1/2 in diameter steel tubes
- Frame
- 3/4 in tube frame
- Latches
- Dual door latches
- Warranty
- 1 year — explicitly excludes 'breakage or damage caused by user or dog'
Pros
- It publishes an actual steel gauge — 20-gauge, with 1/2 in reinforcing tubes — which MidWest will not do
- Genuinely heavy, welded steel construction at a mid-range price
- Dual latches on the door
Cons
- The warranty is the category's central absurdity: this crate is sold 'for powerful dogs that are able to claw or chew their way out of other cages', and the warranty then excludes damage caused by the dog
- One year only
- Extremely heavy; the casters are doing real work
How we assessed it: on published materials, hardware specs and construction — not long-term chew-tested. We say so because it is true, and because a claim we cannot back is worth nothing to you.

3. Diggs Revol Collapsible Crate
Durability score 70/100Best for: A crate you can live with in a living room
The best-designed crate here and a genuinely clever latch — but it is not crash-certified, and its warranty walks away from chewers.
- Materials
- High-strength steel frame, aluminum mesh, reinforced plastic
- Latch
- Two-step latching system
- Capacity
- S up to 30 lb; M 30–50 lb; Intermediate 50–70 lb; L 70–90 lb
- Warranty
- 1 year — excludes 'damage caused by dogs who are not crate-trained or who chew on the product'
- Steel gauge
- Not published
- Crash certification
- None. The Diggs PASSENGER CARRIER is CPS-certified; the Revol crate is not
Pros
- The two-step latch genuinely defeats the paw-and-nose crate escapes that beat a single slide bolt
- Diamond mesh and a collapsing frame that does not require tools
- The only crate here that does not look like a piece of kennel equipment
Cons
- Do not confuse the Revol with Diggs' CPS-certified Passenger Carrier — the crate itself carries no crash certification
- The warranty excludes chewers outright, which is a strange exclusion on a crate this expensive
- Diggs will not publish the steel gauge
- The reinforced plastic components are the obvious attack point for a determined chewer
How we assessed it: on published materials, hardware specs and construction — not long-term chew-tested. We say so because it is true, and because a claim we cannot back is worth nothing to you.

4. Impact Collapsible Aluminum Crate
Durability score 76/100Best for: Travel, if you accept a 2-year warranty that excludes the dog
A well-made travel crate whose warranty is weaker than the brand's reputation implies — and it carries no crash certification.
- Material
- Aluminum, collapsible
- Warranty
- 2 years against defects — NOT the lifetime warranty, and dog damage is excluded
- Dog Damage Protection Plan
- Available as a paid add-on: 2 years, one replacement
- Crash certification
- None — not on the CPS certified list
Pros
- Aluminum construction that folds down for transport
- Impact will sell you dog-damage cover as a separate 2-year plan
Cons
- The Collapsible gets 2 years, not the lifetime warranty many buyers assume they are getting
- Dog damage is excluded from the standard warranty — you must buy the protection plan
- It is not CPS crash-certified, despite being marketed for travel
How we assessed it: on published materials, hardware specs and construction — not long-term chew-tested. We say so because it is true, and because a claim we cannot back is worth nothing to you.

5. SMONTER Heavy Duty Stackable Crate
Durability score 60/100Best for: Two dogs, one footprint
Practical for two dogs. Nothing about its strength or its warranty is documented.
- Design
- Stackable steel crate with divider (Amazon listing)
- Steel gauge
- Not published
- Warranty
- Not published
Pros
- Stacks, so two dogs fit in one footprint
- Heavy steel tube construction at a moderate price
Cons
- No published gauge and no published warranty
- Slide-bolt latches are the easiest type for a clever dog to work open

6. MidWest Homes for Pets Ultima Pro Heavy-Duty Crate
Durability score 43/100Best for: A stronger wire crate — with a hard limit you must understand
A decent home crate for a dog that is not trying to escape. It is not an escape-proof crate and it is emphatically not a car crate.
- Construction
- 'Professional-gauge, heavy duty steel'
- Wire gauge
- NOT PUBLISHED — MidWest will only say 'professional-gauge'
- Latches
- Slide-bolt
- Sizes
- 24, 30, 36, 42, 48 in
- Car safety
- None. CPS: wire crates 'will not provide significant protection in the case of an accident'
Pros
- Heavier wire than a standard folding crate, and the double doors are genuinely useful
- Cheap, and it folds flat
Cons
- MidWest markets it as 'professional-gauge' and then refuses to publish a number. That is marketing, not a spec
- Slide-bolt latches — the easiest latch for a determined dog to defeat
- Never use a wire crate as car restraint. In the Center for Pet Safety's 2015 crate study, MidWest wire crates failed, and CPS's conclusion is that wire crates should be treated as distraction prevention, not protection

A wire crate is not a heavy-duty crate
The MidWest Ultima Pro is a good crate for a dog that is not actively trying to escape. It is a heavier wire crate with double doors, and it is cheap.
It is not an escape-proof crate, and it is emphatically not a car crate. The Center for Pet Safety crash-tested wire crates in their 2015 crate study, and their conclusion could not be plainer: wire crates “should be considered as distraction prevention tools and will not provide significant protection in the case of an accident.” MidWest wire crates were among those that failed. If you are crating in a vehicle, read our crash-tested crate roundup instead.
The verdict
If your dog genuinely destroys crates, the Impact High Anxiety is the only one whose maker will stand behind it when that happens. It is expensive, and the guarantee is the reason it is worth it.
If you want maximum steel per dollar and you accept that the warranty is decorative, the ProSelect Empire publishes its gauge and welds, and nothing else here comes close on price.
If the crate lives in your living room and the dog is crate-trained, buy the Diggs Revol and enjoy it.
Frequently asked questions
Do heavy-duty dog crate warranties cover chewing?
Almost none of them do — which is remarkable, given what the crates are sold for. Gunner's lifetime warranty states it 'does not extend to cover destruction done to the product by the pet'. Lucky Duck excludes chewing and scratching. ProSelect Empire excludes 'damage caused by user or dog'. Diggs excludes dogs who chew. The one exception is the Impact High Anxiety crate, which carries a Lifetime Dog Damage Guarantee: 'If your dog breaks it, we'll replace it.'
What is the strongest heavy-duty dog crate?
For published steel specification, the ProSelect Empire: 20-gauge steel reinforced with 1/2 in diameter steel tubes on a 3/4 in frame, with dual door latches. For a crate that is actually warranted against your dog destroying it, the Impact High Anxiety — the only one on the market with a Lifetime Dog Damage Guarantee.
What gauge steel is a heavy-duty dog crate?
ProSelect publishes 20-gauge steel with 1/2 in reinforcing tubes for the Empire cage. Most other brands will not tell you. MidWest describes the Ultima Pro as 'professional-gauge' without ever stating a number — that is a marketing phrase, not a specification. Diggs and SMONTER also decline to publish a gauge.
Can a dog escape a heavy-duty crate?
Usually through the door, not the panels. Slide-bolt latches are the easiest for a determined dog to work open with its nose, and they are what most cheaper heavy-duty crates use. Dual latches, two-step latches (Diggs Revol) and lockable paddle latches with backup catches (Gunner) are progressively harder to defeat.
Can I use a wire crate in the car?
No. The Center for Pet Safety crash-tested wire crates in its 2015 crate study and concluded they 'should be considered as distraction prevention tools and will not provide significant protection in the case of an accident'. MidWest wire crates were among those that failed. Use a CPS-certified travel crate instead.
