Why Crate Training Makes Sense
A crate is not a cage and it is not a punishment. Done right, crate training gives your dog a personal den, a safe space where they can relax and feel secure. Dogs are natural den animals. In the wild, canines seek out enclosed spaces for rest and safety. A properly sized crate taps into that instinct.
I resisted crate training with my first dog because it felt wrong to me. Then I watched her squeeze herself behind the couch, under the bed, and into the smallest closet she could find every single day. She was looking for a den. When I finally introduced a crate, she walked right in, circled twice, lay down, and sighed. That was it. It became her favorite spot in the house.
Beyond providing comfort, crates are invaluable for house training puppies, keeping dogs safe during travel, preventing destructive behavior when unsupervised, and providing a recovery space after surgery or injury. The key is choosing the right crate and introducing it properly.
Getting the Size Right
How to Measure Your Dog
A crate should be large enough for your dog to stand up without their head touching the top, turn around comfortably, and lie down fully stretched out on their side. It should not be so large that the dog can use one end as a bathroom and the other as a sleeping area, as this defeats the purpose of crate training for house training.
Measure your dog's height from the floor to the top of their head or the tips of their ears, whichever is taller. Then measure length from the tip of their nose to the base of their tail (not the tip of the tail). Add 2 to 4 inches to each measurement to get your minimum crate dimensions.
Crate Size Chart
Here is a general guide, though always measure your individual dog rather than relying solely on breed averages.
| Crate Size | Dimensions (L x W x H) | Suitable For |
|---|---|---|
| Extra Small (18-22 inches) | 18-22" x 12-13" x 14-15" | Chihuahuas, Yorkies, Pomeranians, toy breeds under 10 lbs |
| Small (24 inches) | 24" x 18" x 19-21" | French Bulldogs, Pugs, Boston Terriers, Cavaliers, 11-25 lbs |
| Medium (30 inches) | 30" x 19-21" x 21-23" | Beagles, Corgis, Cocker Spaniels, medium breeds 26-40 lbs |
| Intermediate (36 inches) | 36" x 23-24" x 25-27" | Bulldogs, Springer Spaniels, Staffordshire Terriers, 41-70 lbs |
| Large (42 inches) | 42" x 28-30" x 30-31" | Labrador Retrievers, Golden Retrievers, Boxers, 71-90 lbs |
| Extra Large (48 inches) | 48" x 30-33" x 32-35" | German Shepherds, Rottweilers, Dobermans, 91-110 lbs |
| Giant (54 inches) | 54" x 37" x 45" | Great Danes, Mastiffs, Saint Bernards, 110+ lbs |
Sizing for Puppies
If you are buying a crate for a puppy, you have two options. You can buy for their adult size and use a divider panel to section off the appropriate amount of space as they grow. Most wire crates come with a divider for this purpose. This is the most economical approach. Alternatively, you can buy a smaller crate now and replace it as your puppy grows, which costs more but gives you a better fit at each stage.
For house training purposes, the divider approach is generally recommended. A puppy in a too-large crate will use the extra space as a bathroom, which undermines the house training process. Adjust the divider every few weeks as your puppy grows to maintain the right fit.
Types of Dog Crates
Wire Crates
Wire crates are the most popular and versatile option. They offer excellent ventilation, visibility in all directions, easy cleaning (most have a removable bottom tray), and many fold flat for storage and transport. They typically come with a divider panel, making them ideal for growing puppies.
The downsides: wire crates are the heaviest option, they can be noisy if your dog moves around a lot, and they do not provide the enclosed den feeling that some dogs prefer. A crate cover solves the last issue and can help anxious dogs feel more secure. Wire crates are also not suitable for dogs who are serious escape artists, as determined dogs can bend the wire or force doors open.
Plastic Crates
Plastic crates, also called airline crates or flight kennels, are solid-walled with ventilation openings and a wire door. They provide a more enclosed, den-like environment that many dogs find comforting. They are lighter than wire crates and are the standard for airline travel.
On the downside, they offer less ventilation than wire crates, which can be an issue in warm climates. They do not fold flat, so storage is less convenient. Visibility is limited, which is a pro for anxious dogs but a con for social dogs who like to see their surroundings. Cleaning can be more difficult since the two halves must be separated.
Soft-Sided Crates
Fabric crates with collapsible frames are lightweight, portable, and comfortable. They are excellent for travel, camping, and dogs who are already crate-trained and calm. Many fold down to a fraction of their assembled size, making them ideal for people who move the crate frequently or have limited storage space.
However, soft-sided crates are not suitable for puppies still learning crate manners, dogs who scratch or chew, or dogs with separation anxiety. A determined dog can tear through the fabric or collapse the frame in minutes. Use these only for dogs you trust to be calm and settled in a crate.
Heavy-Duty Crates
For dogs with severe separation anxiety or dogs who have escaped from standard crates, heavy-duty crates made from welded steel, reinforced aluminum, or rotomolded plastic are the nuclear option. They are virtually indestructible but expensive, heavy, and honestly not needed for the vast majority of dogs. If your dog requires this level of containment, working with a veterinary behaviorist to address the underlying anxiety is essential alongside crate management.
Furniture-Style Crates
These crates double as end tables, credenzas, or other furniture pieces. They are aesthetically the most appealing option and blend seamlessly into home decor. The quality range is wide, from flimsy decorative pieces to genuinely solid, well-ventilated crates that happen to look like furniture.
The tradeoff is typically less ventilation, higher cost, and no portability. They are best as a permanent home crate for an already crate-trained dog. They are not suitable for puppies, chewers, or situations requiring a portable crate.
Crate Placement in Your Home
Where you put the crate matters as much as which crate you buy. Place the crate in a living area where the family spends time. Dogs are social animals, and isolating the crate in a basement or spare room defeats the purpose of the crate being a comfortable den within the family space.
Avoid placing the crate in direct sunlight, next to heating vents, or in drafty areas. The crate should be in a spot that is comfortable temperature-wise throughout the day. A quiet corner of the living room or bedroom works well for most families. Many owners have two crate locations, one in the living area for daytime and one in the bedroom for nighttime, especially during the puppy stage when nighttime proximity reduces anxiety and makes overnight potty trips easier.
Making the Crate Comfortable
Add a comfortable crate pad or bed appropriate for your dog. For puppies or dogs who may have accidents, choose a washable, waterproof pad. Avoid loose blankets or towels with dogs who shred bedding, as ingested fabric can cause intestinal blockages.
A safe chew toy or stuffed Kong makes crate time pleasant. The crate should be associated with good things, never with punishment. Never use the crate as a time-out or send your dog there when you are angry. This creates negative associations that undermine the entire purpose of crate training.
Cover wire crates partially or fully with a blanket or purpose-made crate cover if your dog prefers a more enclosed feeling. Leave at least one side uncovered for ventilation. Many dogs immediately become calmer and more settled in a covered crate.
How Long Is Too Long
Crates are not meant for all-day confinement. As a general guideline, adult dogs should not spend more than 4 to 6 hours in a crate during the day. Puppies under 6 months should not be crated for more than 3 to 4 hours, as they cannot hold their bladder longer than that. Overnight crating is different, as dogs naturally sleep for extended periods, but even overnight, puppies will need bathroom breaks.
If your work schedule requires longer absences, consider a dog walker, doggy daycare, or a puppy-proofed room with pee pads and water instead of extended crating. A dog who spends most of their day in a crate is not getting adequate exercise, mental stimulation, or social interaction, regardless of how comfortable the crate is.
Travel Crates
For car travel, a crash-tested crate provides the safest containment. Wire crates can collapse in an accident, so hard-sided plastic or reinforced crates are preferred. Make sure the crate is secured so it cannot slide or become a projectile during sudden stops. Airline travel requires specific crate dimensions and features, so check your airline's requirements well before your trip.
The right crate becomes one of the most useful tools in your dog ownership toolkit. Take the time to size it properly, choose the right type for your needs, and introduce it with patience and positive associations. Your dog will have a safe, comfortable space they genuinely enjoy, and you will have peace of mind knowing they are secure and content.
