Impact Dog Crate vs Gunner Kennel — honest head-to-head for anxious dogs. We compare price, durability, safety & escape-proofing so you can pick the right one.
If you’ve got a dog with severe separation anxiety and you’re shopping in the $500–$800 range, you’re going to hit the same two names over and over: Impact Dog Crate and Gunner Kennel G1. Both are genuinely premium, both are built for dogs that destroy everything else — so which one is actually worth your money?
In this honest head-to-head, we break down impact dog crate vs Gunner Kennel across every category that matters: escape-proofing, crash safety, materials, portability, and price. By the end, you’ll know exactly which one fits your dog and your situation.

Quick verdict
- Choose Impact if escape is the primary concern — your dog destroys crates or has hurt themselves getting out. The welded steel door is genuinely harder to defeat than anything Gunner offers.
- Choose Gunner if you travel frequently and crash safety is the priority. The G1 is the only dog crate with independent crash test data, and it’s meaningfully lighter for the same interior volume.
- Either works for a dog with separation anxiety who needs a secure, calming den — both are quieter and more den-like than wire crates.

Build quality and materials
Impact Dog Crate
Impact uses 6061 aircraft-grade aluminum throughout the body, with a welded steel door. The welds are visible and purposeful — this is a crate built to contain, not to look elegant. The aluminum sides have slats that provide airflow while being impossible for a dog to get purchase on. The crate ships fully assembled; there’s nothing to put together and nothing to come apart under pressure.
The multi-point latch system on the door is the key differentiator. A dog pulling at a single-point latch can eventually work it open through repeated impact. The Impact door distributes that force across multiple contact points, which is why it holds when other “heavy duty” crates don’t.
Gunner Kennel G1
Gunner uses a rotomolded polymer — the same manufacturing process used for premium coolers. The material is impact-resistant, UV-stable, and meaningfully lighter than aluminum for equivalent volume. The G1 doesn’t have the raw containment strength of welded steel and aluminum, but it’s not designed for escape artists — it’s designed to protect a dog in a vehicle collision.
The dual-steel latch is solid. For most dogs with separation anxiety who aren’t actively trying to destroy the crate, it’s more than adequate. For dogs who have broken out of other “heavy duty” crates, it may not be enough.
Crash safety
This is where Gunner wins outright. The G1 has been independently crash-tested by the Center for Pet Safety (the same organization that tests child safety seats) and earned a 5-star rating. It was tested at 30 mph and held the dog inside while remaining structurally intact.
Impact does not have equivalent independent crash test data. The company notes the aluminum construction is inherently strong, but that’s not the same as tested performance. If your dog travels regularly and vehicle safety is a real concern, the Gunner data matters.
If the crate lives at home and crash safety isn’t a factor, this distinction disappears.
Escape-proofing
Impact wins here. The welded aluminum body with steel door is the hardest dog crate to escape from that’s commercially available. Dogs who have broken out of wire crates, plastic airline crates, and other “heavy duty” options have been contained by the Impact.
Gunner is excellent for the vast majority of dogs, but the polymer body can eventually be compromised by a determined dog over time. The dual-steel latch is strong, but the door frame is polymer — a dog applying sustained pressure over weeks of use can eventually create flex.
For severe separation anxiety where the dog is actively working to escape, the Impact is the safer choice.
Ventilation and comfort
Gunner has the edge here. The G1 has integrated ventilation channels plus an optional fan port, which matters in warmer climates or for dogs who run hot. The polymer also doesn’t conduct heat the same way aluminum does.
The Impact crate has aluminum slat sides that allow airflow, but the aluminum body can warm up in direct sun or in a hot vehicle. Both crates are darker inside than wire crates, which many dogs with separation anxiety actually prefer — the enclosed, den-like environment is calming for some dogs.
Portability
The Gunner G1 large weighs approximately 42 lbs. The Impact large weighs approximately 60 lbs. That 18-lb difference is meaningful if you’re moving the crate frequently — loading it into a truck bed, carrying it through airports, or repositioning it in your home.
Both have integrated handles. Neither is light. If portability is a primary concern, neither of these is the right crate — but between the two, Gunner is easier to move.
Price
Impact large: ~$600. Gunner G1 large: ~$800. Both have lifetime warranties. Both are made in the USA.
Neither is cheap. But both are significantly cheaper than the veterinary bills and property damage that come with an escaped dog with severe separation anxiety. At this price point, the choice should be driven by what your dog actually needs — not which one costs less.
Which one is right for your dog?
Choose Impact if:
- Your dog has escaped from other “heavy duty” crates
- The crate will primarily live at home
- Escape-proofing is the non-negotiable requirement
- You’re comfortable with the heavier weight
Choose Gunner if:
- Your dog travels in a vehicle regularly
- Crash safety is a priority
- You need something lighter and easier to move
- Your dog isn’t actively trying to escape — just needs a secure, calming space
The bottom line
For a dog with severe separation anxiety who is actively trying to escape, Impact is the better answer. For a dog who needs a premium, safe space for travel and at home, Gunner is lighter, crash-tested, and slightly better ventilated.
Both crates solve the same core problem: giving an anxious dog a den that feels secure. The right choice depends on whether your dog is an escape artist or a traveler.
