There are three most common materials used – steel, aluminum, and wood. The steel ones are the most durable and an excellent option for the aggressive dogs. The aluminum kennels are a bit lighter but equally as durable, while the wooden ones look the best but aren’t as safe as the two previous versions. For smaller and not aggressive dogs check top soft-sided crates.

On the budget end of the price range is the Smithbuilt self-proclaimed ‘Heavy Duty Dog Crate.’  This industrial looking dog crate is crafted using high-quality steel to make a strong, durable crate that will prove inescapable for a dog and will last for many years. The front door is locked with two slide bolt latches, and the top opening is secured with one. There have been reports that the locking mechanism is weak and can be hugely improved with a standard padlock bought separately. Smithbuilt has made this crate fade, rust, and corrosion resistant by covering it with a multi-layer finish that is better than the powder coat paints on other brands of a dog crate.
It is always wisest to purchase a crate that will last for your dog’s entire life, rather than buying a small one when she’s a puppy and increasingly larger crates as she grows. Instead, go ahead and buy a crate that is suitable for her adult size and use dividers to temporarily shrink the size of the interior. As she grows, you can remove the divider to provide access to the entire crate.

Crates that don’t close securely are pretty worthless, so you’ll want to make sure that any crate you select has high-quality latches. But beware of crates with exceptionally large latching mechanisms, as some dogs will learn how to open the door themselves.  If you have an especially escape-prone pooch, you’ll probably need a crate especially designed for Houdini dogs with double latches or more advanced locking mechanisms.
The simplest and probably most common way is brute force. Do not make a mistake in believing only big dominant dogs and use this method. If there is a point of weakness in your crate – any size dog can exploit it with some force. One of the most common ways dog’s brute their way to escape is by using their heads to force the bars apart. Cheaply made crates and flimsy metal are susceptible to this.
This thing is huge and the price was great, but the design makes for a very challenging effort to assemble or move this. While we don't need to move it often - we do like to bring a kennel for road trips or when we have visitors, it's a pain the rear to disassemble and reassemble. It does not collapse and fold flat like every other kennel I've seen - it uses (4) rods in the corners through metal loops in the sides to keep the structure together. The top, sides, and bottoms simply hook together, but this alone can be a frustrating experience. I put it together alone, but I struggle to think two people would make this easier due to frustration and potential marriage counseling required after This thing is huge and the price was great, but the design makes for a very challenging effort to assemble or move this.

To make matters worse, the packaging materials included styrofoam that must have been damaged in transit. The structural foam had dissintegrated causing a snow storm in the house that was very difficult to vaccuum up because of the static charge. Lastly, the crate pieces were bent when they arrived, so the packaging isn't great for shipping. This further complicated assembly because the hooks that connect the pieces saw the bulk of the damage. My dog doesn't challenge the structural integrity of the kennel, but I would guess an ambitious dog can quickly defeat this enclosure. I would not buy this one again if I could go back. In fact, I am looking for another XXL crate to use for trips so I never have to reassemble this one again... It's just not worth the hassle to return this given the price. … more
Dogs have a natural instinct to have a den enclosure and owners can satisfy these needs by providing them with a crate. Crates are also practical training and housebreaking tool because dogs are naturally averse to soiling in their den. Extra-strong crates can be used to prevent dogs and puppies from destroying their surroundings and chewing furniture.
