If your dog is escaping by forcing apart the crate seams, consider using carabiners or some other type of metal hardware to reinforce these places. Never use things through which your dog can chew, such as zip ties, rope or duct tape. Not all metal carabiners and similar connectors are dog-proof, but high-quality products usually are relatively immune to your dog’s jaws.
The wires used for small crates may not be sturdy or rigid enough to retain their structural integrity when used in big crates. Additionally, large dogs have stronger jaws and teeth than smaller dogs do. Accordingly, you’ll always want to look for crates that feature thick, strong wire (if you opt for a wire-style crate – there are certainly plenty of other options out there too!).
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.

The Smithbuilt cage is well established. It has a tried and tested track record of many customer reviews. So you can feel comfortable with what to expect. Beware of other cheap cages that do not have a good number of customer reviews. You’ll have less reason to have confidence in whether it’ll be suitable or a complete waste of money, or even dangerous for your pet.


Wire dog crates are ideal for pets with long coats or those who live in warmer climates. The continuous air flow keeps them cool while the open design allows them to see their surroundings. Wire and metal dog crate sizes range from X-Small, for a max weight of 20 LBS, all the way up to XX-Large, for a max weight of 140 LBS. While it’s good to know your dog’s weight, you can also reference our crate sizing guide to get a better idea of which size works for each breed.
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.
It was a little more complicated to put together than the smaller crates, but it's perfect. My lab has to have cruciate ligament surgery and his current crate is too small with the cone. It is large enough for him to freely move around and for me to actually go in there with him to give him attention. It's big and takes up a fair amount of space, but I am very happy with the purchase. Hopefully, it will minimize the difficulty of the 12 week recovery for an active dog!
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.
Listen you don’t even have to have a huge dog to have one of these bad boys. I have two of them. I want two more. (I’m not using to potty train) I use them because I have 1 dog who I’ve found on top of our cabinets, stove, window seals, table, fridge.. yes you heard me! She’s 60lbs and she’s a stealthy cat or so she thinks. She’s a danger to herself. I don’t want her falling and getting hurt. So she gets crated. This thing is BIG, it’s like a personal condo for her while we are not home to supervise. Next we have a super chewer, nothing is safe in the house. NOTHING. (Stairs, window seals, couches, pillows, carpets, drywall) he puts his mouth on it. So yup you guessed it he gets a personal condo Listen you don’t even have to have a huge dog to have one of these bad boys. I have two of them. I want two more.

Only go in crates when we are not home which isn’t often. Have a dog with anxiety? These crates have 3 latches. And the metal is thicker, heavy. Seems very well built. Takes two people, this things HEAVY. Pain in the butt to put together but worth every dollar. Love them. … more
Note that some authorities recommend adding 4 to 6 inches on top of your dog’s length when selecting the proper crate size, instead of the 2- to 4-inch guideline we prefer. This is fine if you’d prefer to scale up the crate a little bit, but understand that it is not a good idea to provide your dog with a crate that is too large. Doing so will eliminate some of the benefits crates provide (more on this later), so stay in the 2- to 6-inch range.

A few owners mentioned problems with the crate handle, so you’ll want to be careful when carrying it. Note that some airlines require crates to be fastened with metal, rather than plastic hardware (which is provided with this crate). However, it is easy to pick up some metal bolts and use them to replace the plastic hardware that comes with the crate.
It also has air vents at the tops and bottoms of the sides and rear of the crate. The front door has the greatest level of airflow due to it’s vertical and horizontal crossover bar design. And of course because the crate is made from aluminum, it dissipates heat much faster than a steel crate could. So this is a crate that you could comfortably in multi-climates. The crate won’t get too hot, and it has ample air flow all around.

The next major consideration when choosing a heavy duty crate is portability. Will you be using the dog crate primarily at home – As a part of the furniture, or will you be using it to transport your dog on a camping trip? There are a few dog crates on the market today that is both heavy duty and collapsible making them ideal travel crates. If you are opting for a travel crate, then the best build material will be wood or aluminum for both strength and portability whereas a home crate is best made out of steel for maximum strength and value for money.
As with anything, the best comes at a price, and the Impact Case Collapsible dog crate is no exception! This is a real escape proof dog crate made with absolute precision from quality .063 aluminum which makes it 20% lighter (41lbs) than other dog crates in this category. The strength of the aluminum is complimented with very sturdy rivets. Being made of aluminum makes it also corrosion resistant giving it a longevity that is important when spending this kind of money on a dog crate.
Another drawback is that it's not the best for home use. While it's listed as suitable for dogs up to 75lbs, this is for car journeys when having space to bang around during a crash isn't a good thing. If you're going to use it as a crate for long periods, make sure you choose a bigger version than you think you'll need (there are Small, Intermediate, Medium and Large options).
This crate is available in sizes small to xxx-large, and in a variety of colors including gray, tan, purple, blue, black, teal, white, and lime green.

Why We Recommend It: If your dog escapes from standard wire or plastic crates, the LUCKUP could be the solution. It's built with highly durable steel, has three metal latches on the main door, and comes with two trays to make cleaning easier. It's probably not quite as strong as the Zinger Winger or Grain Valley, but can keep most dogs contained and provides great value.
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.
The Smithbuilt cage is well established. It has a tried and tested track record of many customer reviews. So you can feel comfortable with what to expect. Beware of other cheap cages that do not have a good number of customer reviews. You’ll have less reason to have confidence in whether it’ll be suitable or a complete waste of money, or even dangerous for your pet.
Most of the regular wire crates come with metal connectors – their purpose is to keep the door mounted correctly and the sides connected with each other. Unfortunately, these connectors are often very flimsy, so it’s not a problem for the dogs to mangle them with their teeth and simply escape through the opening afterward. Remember, dogs can chew through almost anything, especially softer materials.
