Most Helpful review (read the full Amazon review): “I needed to know how much this weighed and one listing stated it was 48.8 Lbs I'm not very trusting of website descriptions so I weighed myself and then held the kennel (not easy) and the difference was 43.7. Also to make this airline approved you need to buy metal nuts for the bolts instead of the plastic ones that come with it. You might also need to drill holes in the rear. This is plenty big for my 95 Lb lab mix. He fit in an XL but…“
SmithBuilt is one of the most renowned manufacturers of extra strong metal dog crates – they’re well-known for the comfort and security of their models. Those looking for a reasonably priced indestructible dog crate should consider their newest product, the SmithBuilt Heavy, as it offers good construction quality, a convenient 2-door design, and a removable pan for easy cleaning.

Most Helpful review (read the full Amazon review): “It sure is a good thing I checked amazon.com for dog creates before spending almost twice as much at a major pet store! This crate is perfect in every way. It's very well made and the price can't be beat. The bottom plastic tray can be easily removed for cleaning and the crate collapses very easily. It's pretty easy to open and close with the double sliding…“


Features: The Petmate Sky Kennel is primarily built of sturdy, high-quality plastic, but it still provides great ventilation to keep your pet comfortable. The front door is made of steel wire, as are the two windows on each side, and the back of the crate is perforated plastic. The door features a vault-style latch and is secured in four places for maximum security.
The reason this crate doesn't rank as highly as the Empire is that it's not quite as escape-proof. I think the top door might be a weak point, so you may want to use a zip tie to stop it opening if you don't plan on using it. The most determined and strongest chewers may be able to attack the bars though - so for these dogs look for sheet-walled crates instead.

Several owners complained that their dog was able to bend the wires and escape, so this isn’t a good choice for dogs who are escape artists, although it should serve fine for most pooches. Additionally, a few owners reported that while the crate can be collapsed, it’s not especially easy to do, so it isn’t a great choice for owners who plan to travel with the crate frequently.

Most models come with wheels – they are mandatory. Some models don’t, and we advise you to avoid them as moving them around is a real hassle, especially if you travel often. Crates with wheels will allow you to easily transport your pooch no matter the circumstances. For the less portable solution, you might as well go with an outdoor kennel or a good quality playpen.


Why We Recommend It: The Zinger Winger DX5000 is probably the toughest and most durable crate I've reviewed. I wouldn't call any crate 100% inescapable, but the aircraft-grade aluminum and stainless steel slam latches mean the DX5000 is a match for almost any dog. It's also lightweight (compared to other heavy duty models) and has lots of ventilation - the only downside is the price.

The more robustly built market value priced ProSelect dog cage. is a better choice if you feel that your dog is of an escape or jailbreak temperament, due to its quality, build, strength, and reliability. And this is backed up with a significant volume of customer reviews. However if you feel it’s too expensive and can’t stretch your budget to get it, then you may like to consider the SmithBuilt crate.

Keeping the dog inside is not the only purpose of a pet crate – it also protects the pooch from the dangers of the outside world. During the journey, a kennel has to withstand things like scrapes, bumps, and occasional knocks without breaking apart. Therefore, the heavy-duty models are your best choice – they’re sturdier and more durable than the regular crates.

Just like with all other equipment, the market is oversaturated with various brands and models of so-called chew-proof and inescapable cages that can’t live up to the task. It can be really challenging to find one that will genuinely suit the needs of your dog, especially if you don’t know a lot about these items.
