Dog crates are much more paw-pular now than they ever have been before. Maybe because there are so many choices of types, materials, and sizes.
These are not just big plastic boxes to put your dog in after all. He is your best fur-iend and you want him to be comfortable as well as safe. And some dogs really need to be crated while you are not home to keep them from eating the furniture or the cat.
With the proper crate, you should be able to keep your Houdini dog comfortable as well as safe.
Using an inferior crate or one that can be bent or pushed open can be very dangerous to your fur baby. He can become hurt when breaking out or get trapped during his escape attempt.
After evaluating more than 30 indestructible dog crates, I chose the “ProSelect Empire crate” as my favorite because It has extremely strong steel bars with two sliding locks that pups cannot get to.
And it has locking wheels so you will not have trouble moving it. Your pup will love it too since he can see everything around him and it has comfortable flat slats on the bottom.
But I understand you might have different needs, whether you’re looking for an indestructible dog crate for your escape artist or a crate for car rides. That is why I prepared a shortlist of our favorite indestructible dog crates that address different styles & needs.
Before we dive into the review section below, we’ll explain why your dog keeps escaping his crate, we’ll guide you step by step on how to choose the right size, and what criteria you should use to make the best selection for your needs.
In addition, we’ll answer some common questions from dog parents, and give you some tips on how to train your dog to love his crate.
So let’s get started.
First, a few words on Why Your Dog is Escaping from His Crate?
Do you have a magician fur baby who seems to be able to get out of his crate no matter what you do to stop it? Some dogs are just “escape artists”. He may be bored, lonely, stressed, or he may just like the challenge of getting out of the crate.
For example, if you leave your Fido alone in the crate while you are at work and then again when you go to bed, he may not be getting enough stimulation. Here are some other reasons why dogs escape their crates.
- Boredom: Any pup that is less than three years old is still considered a juvenile and you know how juveniles get when they do not get their way. They throw a temper tantrum! Your pup’s way of throwing a temper tantrum is doing anything paw-sible to get out of that crate you put him in.
- Breeds: There are certain breeds that need to be doing something to be happy. You probably know humans like that too. Some of these include Anatolian shepherds, Siberian huskies, Australian cattle dogs, vizslas, border collies, and mastiffs.
- Looking for a mate: If your dog is not spayed or neutered, they may be looking for a mate. It is their instinct to do so and there is no real fix for this besides getting your dog spayed or neutered.
- Fear: Your pup may be scared of being alone or maybe they have a fear of small places. Yes, dogs can have phobias too. For example, thunderstorms and other loud noises may be freaking your dog out and he wants to get out of the crate to go hide somewhere.
- Separation anxiety: If your dog escapes right after you leave the house, they probably have separation anxiety. Dogs that are strongly attached to their owners sometimes have a hard time being without them.
- Wrong size: If your dog’s crate is too small, he is not going to want to be cooped up in there. Would you want to be in a tiny box that does not allow you to move? Your dog has to be able to stand up, turn around, and stretch out to be comfortable.
Choosing The Right Crate Size
Although it may seem like you can just go and get the largest crate you can find that will fit in your house and it will be paw-fect, that is not the case. Not only can a crate be too small for your dog but they can also be too large for your dog.
Although some crates are selected by the weight of your fur baby, you really should go by your dog’s size. Because a long and tall greyhound and a short chubby pomeranian may be similar in weight but they are definitely not the same size!
How Big Should a Dog Crate Be?
So, your dog’s crate should be just big enough for them to lay down, stretch out, turn around, and stand up without trouble but it should not be any bigger than that.
Giving them too much room can encourage them to sleep on one side and relieve themselves on the other, and you do not want that.
Measure your pooch by length and height and add two or three inches. This will give you the length and height your pup needs.
Measuring an adult dog
Measuring your dog is pretty easy but you need him to be in a relaxed mood when you do it. Trying to measure a pooch that wants to play can be a bit stressful for both of you.
Wait until he is chilling out and be sure to give him a treat afterward. Also, If you plan to have a bed in there for your pup, make sure you add that into the measurements.
- Length: To measure your fur baby’s length, go from the tip of his nose to the end of his body. Then add two to four inches for extra space. You do not have to include his tail unless it happens to be extra thick or fluffy.
- Height: To measure your pup’s height, have them sit down and measure from the floor to the top of their head. Add two to four inches depending on your dog’s build.
What about puppies?
Puppies can be measured for the right size crate but you have to remember that they are not done growing yet.
Your three-month-old Labrador Retriever maybe 12 inches tall right now but by the time he is full-grown, he may be triple that size. A two-year-old Labrador can be up to 25 inches tall!
Luckily, they sell crate dividers (or puppy dividers) that you can put in the crate to make it smaller for him as a pup so you only have to buy one crate rather than buying a small one now and a larger one later.

11 Rules Of Thumb When Buying an Indestructible Dog Crate
Whether to crate your dog or not is a big decision and many pet parents have strong opinions on the matter. Some say no way while others would not be without one. But your dog really should have a place to call his own. A space that is just his. And it is also great for potty training. Dogs have the natural instinct not to go potty inside their den and since the crate is essentially their den, they typically do not “go” in there.
- Heavy-Duty Metal: Although some crates are made of other materials like wood or plastic, metal is the most durable material that you can get. It works wonders in keeping those escape artists where they belong. Stainless steel and strong aluminum are two good choices.
- Non-Toxic Material: You always need to check anything your dog will be using for toxic materials. Just like a baby, anything they can put in their mouth, they will. In the case of crates, if you have a plastic one that is made of polyvinyl chloride (PVC), that is bad but high-density polyethylene (HDPE) is good. Other ones to watch out for include phthalates, polyethylene terephthalate (PET), and polystyrene (PS).
- Your Dog Size: As long as you measure your pup using the directions we mentioned above your dog should be fur-fectly comfortable in his crate.
- Ventilated Walls: For your pooch to have adequate airflow, it is important to have ventilation on at least two sides of the crate. The openings should be a minimum of one inch over the upper two-thirds of the opposite end and the remaining two sides, at a distance of four inches from center to center of each opening. The total ventilated area should be at least 16% of the total surface of all four sides.
- Portability & Removal Wheels: If you have a heavy or large dog and you travel a lot, a crate with wheels is a pawesome invention. Dragging a heavy metal crate along the floor is not easy. However, if you fly, some airlines require the wheels to be removed or taped securely when you check them because they do not want them to roll around on the plane.
- Locking Mechanism / Latch Type: Besides material, the lock or latch type is the most important feature. On a heavy-duty dog crate, the latch is the most common weak point that your pup is able to use to his advantage. Make sure yours has more than one locking latch and that it is made with high-quality welded metal.
- Durability: The whole point of a dog crate is to be durable for your dog because dogs can be “ruff” on their stuff. It is best to get something of steel or other strong metal and be sure it is thick enough to stand up to your pup.
- Ease Of Access: Some dog crates only have one door on the front while others have a door on the top too. This is pretty important when you are trying to get your dog out of the crate and he does not want to come out.
- Rust Resistance: Whether you plan to use the crate outdoors or not, it is likely to come into contact with some kind of moisture. For example, your pet may have an accident if you get home late and they just could not hold it any longer. So, make sure whatever crate you get is made with rust-resistant metal or coated with a rust-resistant coating.
- Removable Tray at the bottom / Ease of cleaning: Having a removable tray at the bottom makes cleaning your pup’s crate so much easier. If you have ever had to clean one of the extra-large crates that have one door and a solid floor, you probably had to climb in there and clean it from the inside. That is not fun.
Warranty: Any company that does not provide any kind of warranty is probably not a company that you want to buy from. No matter how much you are spending, you should make sure you are getting some kind of warranty. Especially for those expensive crates. - Made In The USA: Although other companies in countries besides the United States may follow the strict guidelines the US keeps in place, you do not really know this unless it is really made in the USA.

Common Questions from Dog Parents
Should I cover my dog’s crate with a blanket?
If you have a dog that is anxious or searches for dark enclosed places when he is scared, a cover on his crate can make him feel safer. It helps block out the noise and distractions from outside the crate that may be irritating him and gives him a sense of security.
Should dogs sleep in crates?
Your dog may love having his own space in the crate and if you want him to sleep in there, place his favorite bed inside and leave the door open. He will soon be going in there on his own just to go to sleep. Giving your pup a nice comfy place to sleep in his crate can be a very good experience for both of you.
Crate training will provide many benefits to pet parents. Having a crate that is properly sized (more about that below) is essential to your pup’s instinct of not messing where he sleeps. This helps your fur baby learn to control his bladder and bowel control. Keeping his crate clean is important to housetraining your new puppy or rescue.
Another benefit of having a crate for your dog is that it helps to keep your pup out of trouble when you cannot be there to supervise. For example, if you are busy cleaning, cooking, at work, or when you are sleeping, you cannot focus completely on your dog as you would like to.
Is it cruel to crate a dog while at work?
Some people think crating your dog is cruel but a crate is supposed to be a bonus for your pooch, not a punishment. That being said, it is also a tool and preventative measure to keep your dog from tearing up your home when you are gone or sleeping. Crating your dog is only cruel if you leave him in there all the time and never give him attention.
Avoid crating your fur buddy for longer than five hours at a time unless you are sleeping or at work and the frequency should be minimal. When your pup is crated for long periods of time, it can lead to anxiety and depression because they get no interaction and exercise that they need to be physically and mentally healthy.
What can I put in my dog’s crate that he won’t chew?
If you have read some of our other articles on chew toys and indestructible toys, you know that there are many toys that are good for your pooch to play with alone and then there are the ones that are not. First, put your pup’s bed in there or a blanket that he likes.
Then you can add one or two very durable chew toys that are listed as very durable like the Kong Extreme.
Tips on How to Stop Your Dog From Escaping & Destroying His Crate
Although getting a durable dog crate and reinforcing it as much as you can will help, it is not enough to just worry about the crate. You have to worry about why your pup is trying to escape the crate. As we mentioned above, your dog probably has a very good reason to try to get out of his crate. He may be bored, have too much energy, spend too much time in the crate, the crate is the wrong size, or your pooch has separation anxiety.
- Boredom: Make sure your pup has a good toy in there with him to play with. But be sure that it is a durable chew toy that will not break into pieces. And make sure he likes it, otherwise he will still be bored.
- Breeds: Because some breeds need to be working when they are not sleeping, your best bet here is to wear him out. Take your dog to the dog park and let him run with the pack or take him on a run with you in the neighborhood. As long as you give him enough exercise, he should be okay with staying in the crate for a while.
- Looking for a mate: As previously mentioned, if you get your dog spayed or neutered they will not have this issue to worry about.
- Fear: Figure out what it is that your dog is afraid of and fix the problem. He may be afraid of loud noises he hears during the day. To solve this, turn on the television or a fan to provide noise that will cover any other noises he may be hearing.
- Separation anxiety: There are many products on the market that can help you with separation anxiety. For example, there are cameras with sound that will help you see what your pup is doing and talk to him if he seems anxious. Just give him a few words of praise when you can during the day while you are not home and he may relax and enjoy his crate.
- Wrong size: Make sure you use the above instructions for getting the right size crate for your pooch. You do not want him to be cramped into a small space and not be able to move around all day.
The Final Woof
Although the top winner only comes in two sizes, the sizes they have will fit almost any dog out there. And with the nickname of the “Alcatraz of dog crates” the ProSelect Empire crate is the best. It has extremely strong steel bars with two sliding locks that pups cannot get to.
And it has locking wheels so you will not have trouble moving it. Your pup will love it too since he can see everything around him and it has comfortable flat slats on the bottom. The others may have some of these features but not at such a decent price so this is definitely the best indestructible dog crate.
