Choosing a Crate for an Adult Dog That Has Never Used One

Start with the dog, not the crate

An adult dog that has never used a crate is learning a new skill, so the first purchase should feel like a quiet resting place, not a penalty box. The ASPCA recommends that every dog has a warm, quiet place to rest away from drafts and off the floor, and lists a training crate or dog bed as ideal, with a clean blanket or pillow placed inside. Keep that comfort goal in mind when you compare models.

Before you look at crates, measure your dog. Crate sizes are based on length and height, and measuring correctly keeps you from guessing between sizes. Start with our guide on how to measure your dog for a crate and then line up your measurements with a dog crate size chart.

Size for standing, turning, and lying down

The first physical check is body size. The crate must be long enough for the dog to stretch out, tall enough to sit upright with the head raised, and wide enough to turn around. For an adult dog that has never been crated, a slightly larger space makes the first few sessions feel less confining. If you are between two sizes, choose the larger one.

Manufacturers state overall dimensions and interior dimensions differently, and the interior space is what the dog actually feels. Compare interior vs exterior crate dimensions and review how much room a dog really needs in a crate before you settle on a size: how much room does a dog need in a crate.

Sizes also vary from brand to brand, so the same crate name can mean different lengths and heights. Check the spec sheet for the model you are considering rather than assuming a label means a certain size.

Check the door width and opening

A door can look fine from the front yet still be too narrow for a nervous dog that is unsure about entering. For a first crate, compare the actual door opening with your dog's body, not just the total crate length. The dog should be able to walk in without crouching, turning sideways, or squeezing its chest against the frame.

Front doors and side doors both work, but a second door can be a big help because it gives the dog another route in and out while you are training. Review the door height and opening size guide and the single vs double door comparison before you choose.

Latch ease and escape resistance

Latches matter in two directions. You need a latch that opens smoothly with one hand, so you can release the dog without looming over the door or reaching inside suddenly. The dog needs a latch that stays closed, because an adult dog can learn to work a simple slide bolt, especially when it is anxious.

The ASPCA notes that dogs with separation anxiety may attempt extreme escapes that can result in self-injury and household destruction. If your adult dog has ever shown signs of anxiety around confinement, prioritize secure latches and a sturdy frame. Compare crate latch types and look at escape-proof dog crates for designs with sturdier closures.

Comfort, bedding, and placement

A bare metal tray is not inviting, and an adult dog deciding whether to trust a crate will look for a soft place to rest. The ASPCA suggests a clean blanket or pillow inside a training crate or dog bed and washing the bedding often. Choose a mat or bed that fits the tray without folding up at the edges.

Ventilation also affects comfort. Wire crates allow more airflow and visibility, while plastic kennels are more enclosed and den-like. Think about the room temperature and your dog's coat when you decide: see the ventilation guide for the trade-offs.

Cleaning matters just as much as the first impression. The CDC recommends washing hands after handling pet habitats and supplies and cleaning pet gear away from food preparation areas, which is a good reason to choose a crate with a removable tray and washable bedding: see the easy-to-clean dog crates guide.

Teach the adult dog that the crate is safe

Adult dogs that have never used a crate may pace, whine, or try to leave as soon as the door closes. The ASPCA describes separation anxiety as distress triggered by separation from attached people, with symptoms that include barking, howling, chewing, digging, and escape attempts. If you see those behaviors, do not punish the dog. Close the door for very short periods, stay nearby, and build up slowly.

Feed meals near the crate, toss treats inside, and keep the door open at first so the dog can explore on its own. If the dog cannot settle even with a slow introduction, consult a veterinarian or behavior professional and review the guidance for crates for anxious dogs.

Plan for travel and transport

If the first crate will also travel, check folding, weight, and whether it fits in your vehicle. The USDA points out that international pet travel takes planning and may require a USDA-accredited veterinarian and destination-country paperwork, while CDC rules apply to dogs entering or returning to the United States. A crate that is easy to fold and carry makes those trips simpler.

For car travel, a secured crate is safer for the dog and everyone else in the vehicle. Compare folding vs non-folding crates if the crate will leave the house.

What to pick for your use

Questions

Will an adult dog ever accept a crate?

Yes. Many adult dogs learn to use a crate when it is introduced gradually and paired with food and rest. The ASPCA lists a training crate as an ideal quiet resting place and recommends a clean blanket or pillow inside. Keep early sessions short, leave the door open at first, and never use the crate for punishment.

Which crate type is best for a first crate, wire or plastic?

Wire crates give more airflow and visibility, while plastic kennels feel more enclosed and den-like. Either can work for an adult dog. The more important checks are size, door width, and latch ease. Choose the type that matches your dog's temperament and the room where the crate will live.

How do I know if the door is big enough?

Compare the door opening with your dog's shoulder height and chest width. The dog should enter without crouching or squeezing sideways. If the dog hesitates at the entrance, a wider or taller door usually solves the problem.

What should I do if my dog tries to escape the crate?

Stop closing the door for a while and check the latches for anything a dog could paw or nudge open. The ASPCA warns that escape attempts linked to separation anxiety can cause self-injury and household destruction. If the dog panics, slow down the training and talk to a veterinarian or behavior professional.

Can I leave the crate door open during the first days?

Yes. Leave the door open, put meals and treats near the entrance, and let the dog go in and out on its own. Once the dog rests inside regularly, begin closing the door for very short periods while you stay nearby.

What bedding should I put inside?

Use a washable bed or mat that fits the tray, and clean it often. The ASPCA suggests a clean blanket or pillow inside a training crate and regular washing. Avoid oversized bedding that bunches against the door or that a determined dog can shred.

Should I pick a crate with two doors?

A second door can help with placement and gives an inexperienced adult dog another way in and out, which often makes the first crate less intimidating. Two doors also make cleaning and access easier in tight rooms.
