Dog crate sizes and crate training your pet doesn’t have to be scary! When it comes to choosing one suitable and safe, there are a few things to take into consideration. From small to large ones to even the biggest sized options, there are a few things you should keep in mind when shopping for the perfect fit.
A crate too small will restrict her movements leading to cramping and may be seen as a negative space. For bigger breeds, you want one that will accommodate the size of your pet without getting in the way of your everyday activities. Another consideration to keep in mind is choosing an adjustable option for your growing puppy.
Crates can also be a great training tool for the average pet owner and can lead to benefits for both you and your pal.
Have you ever thought “the bigger the better” when shopping for your furry friend’s crate? I used to believe that too! After all, who wouldn’t want to give their beloved pup more space to stretch out and relax? But here’s the surprising truth – a dog crate actually CAN be too big, and it might cause more problems than you’d expect.
As a pet parent who’s made this mistake before I want to share what happens when your dog’s crate is oversized and why proper sizing matters more than you might think.
The Unexpected Dangers of an Oversized Dog Crate
When I first brought home my Lab puppy, I bought the biggest crate I could find, thinking I was being kind. Big mistake! Here’s what can happen when your dog’s crate is too large:
Housetraining Setbacks
One of the biggest problems with an oversized crate is how it affects potty training. Dogs naturally avoid soiling their sleeping area. In a properly sized crate, they’ll hold it because there isn’t enough space to designate a “bathroom corner.” But in a too-large crate your pup can easily
- Create separate areas for sleeping and eliminating
- Develop bad habits that are hard to break
- Experience significant setbacks in housetraining progress
My puppy started using one corner of his oversized crate as a bathroom, which completely undermined our housetraining efforts It took weeks to correct this behavior after switching to a properly sized crate!
Increased Anxiety and Insecurity
This one surprised me the most. We assume more space equals more comfort, but for dogs, the opposite is often true:
- A properly sized crate mimics a natural den, creating security
- Oversized crates can feel overwhelming and exposed
- Dogs may struggle to relax and settle in too much open space
- The lack of den-like security can trigger anxiety
Dogs with too much crate space often pace, whine, or bark because they don’t feel secure. My dog would pace in circles in his big crate instead of settling down to sleep.
Development of Destructive Behaviors
Boredom and anxiety in an oversized space can lead to:
- Destructive chewing of bedding or the crate itself
- Digging behaviors
- Excessive barking and whining
- Self-soothing behaviors like excessive licking
Difficulty with Crate Training Acceptance
When a crate is too big, dogs often:
- Show hesitation or resistance to entering
- Take longer to acclimate to the crate
- Associate the crate with negative feelings rather than seeing it as a safe haven
Safety Concerns
A larger crate can actually create safety issues:
- More room to gain momentum and potentially injure themselves
- Increased leverage for escape attempts
- Greater risk of getting paws caught in wire mesh
How to Choose the Right Crate Size
So what’s the perfect size? A properly sized crate should be just large enough for your dog to:
- Stand up without hunching
- Turn around comfortably
- Lie down stretched out
That’s it! No extra room needed.
Measuring Your Dog for the Perfect Fit
To get the right size crate:
- Measure your dog’s height from the top of their head to the floor when standing normally
- Measure length from the tip of their nose to the base of their tail
- Add 2-4 inches to both measurements to get your ideal crate dimensions
For my 65-pound Lab, a 42-inch crate was actually too big. A 36-inch crate with adequate height was the perfect fit!
The Puppy Problem: Planning for Growth
If you have a puppy, you’ll need to consider their future size. I recommend:
- Buying a crate that will fit their adult size
- Using a divider panel to reduce the space while they grow
- Adjusting the divider as your puppy gets bigger
This approach saves money and ensures the crate is always the right size during those crucial housetraining months.
What to Do if Your Dog’s Crate is Already Too Big
If you’ve already purchased an oversized crate, don’t worry! There are solutions:
Use a Divider Panel
Many wire crates come with divider panels, or you can purchase one separately. This is the most effective solution as it physically reduces the usable space.
Create a Cozier Space
If a divider isn’t possible:
- Add extra bedding to fill some of the space
- Place toys strategically to reduce open areas
- Consider a crate cover to create a more den-like atmosphere
Consider a New Crate
Sometimes the best solution is to invest in a properly sized crate. Trust me, it’s worth it for your dog’s comfort and your training success!
Are There Exceptions to the “Not Too Big” Rule?
While the general rule is to avoid oversized crates, there are a few exceptions:
- Dogs with medical conditions requiring extra space for bandaging or limited mobility
- Multi-dog households where dogs prefer to share a crate (though individual crates are usually better)
- Temporary situations where a properly sized crate isn’t immediately available
In these cases, close supervision and more frequent potty breaks are essential to prevent the problems associated with oversized crates.
Beyond Size: Other Important Crate Considerations
While size is crucial, don’t forget these other factors when choosing a crate:
Crate Material
- Wire crates: Good ventilation, visibility, often come with dividers
- Plastic crates: More den-like, less visibility, better insulation
- Soft-sided crates: Lightweight for travel, not ideal for puppies or chewers
Crate Style and Features
Look for:
- Secure latches that your dog can’t manipulate
- Removable trays for easy cleaning
- Rounded edges for safety
- Multiple entry points for flexibility
Real Talk: My Experience with Crate Sizing
When I downsized my Lab’s crate from a 42-inch to a 36-inch, the difference in his behavior was amazing. He settled faster, slept better, and had zero accidents. The smaller space helped him feel secure rather than exposed, and his anxiety-related behaviors like whining and pacing stopped almost immediately.
It seems counter-intuitive, but dogs really do prefer smaller, cozier spaces that tap into their natural denning instincts. My mistake of “going big” actually made crate training harder, not easier!
The Bottom Line on Crate Size
So, can a dog crate be too big? Absolutely yes! A properly sized crate:
- Supports natural denning instincts
- Aids in housetraining
- Reduces anxiety and stress
- Prevents destructive behaviors
- Creates positive associations with the crate
Remember that your dog’s crate should be their sanctuary – their own personal den where they feel safe and secure. By choosing the right size, you’re not limiting their freedom; you’re actually providing them with the comfortable, secure space they naturally crave.
Have you had experience with crate sizing for your dog? I’d love to hear what worked (or didn’t work) for you and your furry friend!

Choose the Right Size
The small option is best for dogs in the toy group that are small in stature and on the petite side. Dogs in the toy group include, Japanese Chin, Pug, Pekingese, the Terrier group and many more.
The medium option is best for mid-sized. This category can range from small- medium such as a Welsh Corgi and a French Bulldog to a medium stature like a Beagle or Border Collie.
The larger options are best suited for big breeds. These have a slightly larger stature but also do not reach the largest category. Large ones include breeds like Golden Retriever, the Lab family and German Shepherds.
The extra-large ones are for the biggest breeds with a tall stature and a heavy weight. Included in this group are Great Danes, Mastiffs and Saint Bernard’s.

How to Measure Your pet
Measuring is the most important step when determining what size you will need.
Starting with height, measure while standing or sitting. You want to measure them at their tallest point. Measure from the ground to the top of the head. This measurement will help you make sure he has a comfortable amount of space to sit up in there.
The next step is to measure the length of your animal. Measure them from the nose to the base of their tail. Reminder: if you measure to the end of the tail, the area will be too large.
While most have weight restrictions, you will want to weigh it. You can do this by taking them to the vet or by stepping on the scale with them at home.

FAQ
How do I know if my dog’s crate is too big?
How much room should your dog have in their crate?
Make sure to add some wiggle room to these measurements to ensure your dog feels comfortable in their crate. While you don’t want them to swim in empty space, they also shouldn’t feel cramped. A good rule is to add four inches to both their height and their length measurements.
How much bigger than a dog should their crate be?
Your dog’s crate should allow them enough space to stand up, turn around and lie down comfortably without being cramped. The ideal size is their length and height plus approximately 10cm.
Can a Great Dane fit in a 48 inch crate?
Given their impressive size, Great Danes require a crate that allows ample room to stand, turn, and stretch. Here are our most recommended sizes: 48-inch 2XL High Anxiety or Stationary Crate (48.5″L x 32.5″W x 36″H): Suitable for most adult Great Danes, this size provides the perfect balance of space and security.
