Introduction
Choosing the right kennel size is a critical step in ensuring your dog feels safe, comfortable, and happy. A kennel that's too small can cause stress and discomfort, while one that's too large may leave your dog feeling exposed and insecure. Sadly, many pet owners overlook this aspect and end up purchasing kennels that don't meet their pup’s needs.
The right kennel provides a cozy space your dog can call its own—a secure retreat for rest, relaxation, or even training. Whether you’re a first-time dog owner or replacing an old kennel, understanding size requirements will make a world of difference in your dog’s wellbeing. And if you’re browsing for great options, check out this curated collection of dog kennels at PetsGear tailored to fit all breeds and preferences.
Let’s dive into the specifics to help you pick the perfect fit.
The Importance of a Properly Sized Kennel
A well-sized kennel is like a perfectly fitted suit—just right makes all the difference. A kennel that's too tight will make your dog feel cramped and frustrated. On the flip side, an overly spacious kennel can trigger anxiety and reduce the effectiveness of crate training.
Dogs instinctively seek out dens—a properly sized kennel mimics that cozy den-like space, offering your pet a sense of security and calm. It becomes their private zone where they can retreat to nap, chew on a favorite toy, or relax during a thunderstorm.
Safety is another big factor. If your dog slides around too much inside or can’t turn comfortably, the risk of injury increases. Also, larger spaces in travel kennels might lead to unexpected messes as dogs could be more likely to relieve themselves.
Comfort, behavior, and safety—three major reasons to take sizing seriously when buying a kennel.
Measuring Your Dog for the Perfect Fit
Getting your dog’s measurements right is the foundation for choosing the perfect kennel. You don’t need fancy tools—just a tape measure, your dog, and maybe a treat or two to keep them still.
Tools You’ll Need
-
Flexible measuring tape
-
Pen and paper (or phone notes)
-
Treats for cooperation
Step-by-Step Measuring Guide
-
Length: Measure from the tip of the nose to the base of the tail (not including the tail itself).
-
Height: Measure from the floor to the top of the head or ears (whichever is taller when your dog is standing).
-
Width: This is usually proportional to length, but a rough guide is to allow your dog to turn around comfortably.
Add about 5–10 cm (2–4 inches) to each measurement to ensure your dog has enough room to move without turning the kennel into a playground.
Breed Considerations
Some breeds are taller when sitting (like Great Danes), while others have broad chests (like Bulldogs). Keep your dog’s unique build in mind when choosing dimensions. Puppies? Go adjustable or size up, but with dividers to limit the space temporarily.
Kennel Size Guidelines Based on Dog Size
While measuring your dog is always the most accurate method, it helps to have a general size chart as a reference. Most kennel manufacturers categorize their products by weight range and breed size. Here’s a quick guide to help you identify the ideal kennel dimensions based on your dog’s size:
Small Breeds (Up to 10 kg)
-
Examples: Chihuahua, Yorkshire Terrier, Pomeranian
-
Recommended Kennel Dimensions: Approx. 55cm L x 40cm W x 45cm H
Small dogs need a compact, snug space that helps them feel secure. Too much room may overwhelm them. Make sure the kennel still has proper airflow and space for a cushion or small bed.
Medium Breeds (10–25 kg)
-
Examples: Beagle, Cocker Spaniel, Border Collie
-
Recommended Kennel Dimensions: Approx. 75cm L x 55cm W x 60cm H
These dogs need a balance of coziness and space. They should be able to stand, stretch, and turn easily. Make sure there’s enough room for food and water bowls if they’ll be spending longer periods in the kennel.
Large Breeds (25–45 kg)
-
Examples: Labrador Retriever, Golden Retriever, Boxer
-
Recommended Kennel Dimensions: Approx. 90cm L x 60cm W x 70cm H
Larger dogs require solid construction and durable materials in addition to proper space. Always check if the kennel is reinforced, especially for outdoor use.
Extra-Large Breeds (Over 45 kg)
-
Examples: Great Dane, Saint Bernard, Mastiff
-
Recommended Kennel Dimensions: 110cm+ L x 75cm+ W x 90cm+ H
These gentle giants need heavy-duty, oversized kennels with plenty of legroom. Custom-built or modular kennels are often the best option.
A kennel that fits well will help your dog feel safe and comfortable, especially during times of stress or travel. If your dog is between sizes, it’s usually better to size up slightly and add a divider or extra bedding to customize the space.
Types of Dog Kennels and How Size Applies
The type of kennel you choose also influences how important exact sizing is. Let’s look at the different styles and what size considerations come with each:
Indoor Crates
These are usually wire or plastic models meant for temporary or overnight use. Because they’re used inside, aesthetics and space-saving become a priority.
-
Make sure it fits your dog and fits your home.
-
Use dividers for puppies or for crate training.
Outdoor Kennels
Typically larger and more robust, outdoor kennels can include runs, weatherproof roofs, and insulation.
-
They allow more space to move but still shouldn’t be overly large to prevent heat loss or exposure.
-
Important for active breeds or dogs that spend extended time outside.
Travel Kennels
Used for car trips or airline travel, these are usually enclosed and compact to keep dogs secure.
-
Must be compliant with airline regulations.
-
Size is vital here for both safety and comfort—too big can be dangerous during transport.
Choosing a kennel type that matches your lifestyle helps narrow down sizing options quickly. Each kennel serves a different purpose, so think about how and where you'll use it most.
Growth Considerations for Puppies
Buying for a puppy can be tricky. You want a kennel they’ll grow into, but not one so large that they feel lost in it—or use it as a bathroom.
Go Bigger, But Smarter
The solution? Dividers. Many wire and plastic kennels come with adjustable divider panels that allow you to resize the interior space as your pup grows. This gives you flexibility without having to buy multiple kennels over time.
Predict Adult Size
Research your puppy’s breed or ask your vet to estimate their adult size. Breed charts can give you a general idea, but also observe your dog’s growth rate and structure. If you have a mixed breed, play it safe and buy slightly larger, but not oversized.
Safety for Growing Dogs
A kennel should never restrict movement or development. Make sure your puppy can stand up without crouching, and avoid overly soft structures that can collapse or be chewed through.
As your dog grows, regularly reassess the fit and adjust accordingly. Proper sizing during the growth phase ensures healthy development and good kennel habits.
Behavioral Factors to Consider
When choosing a kennel size, it's not just about height and length—your dog's behavior plays a big role too. Every dog has a different personality, and their comfort level in a confined space depends on how they interact with their environment.
Active vs. Calm Dogs
Active breeds, like Border Collies or Australian Shepherds, tend to get bored or anxious in tight spaces. While you still want a cozy environment, these dogs may benefit from slightly larger kennels with room for stretching and playing with a toy.
Calmer breeds or older dogs, on the other hand, prefer smaller, den-like spaces. They’re more likely to appreciate the coziness of a snug kennel that feels like a warm cocoon.
Dogs with Anxiety
For dogs with separation anxiety or nervous temperaments, a kennel that’s too open or large might make them feel insecure. In these cases:
-
Choose kennels with partial coverage or add a blanket over the top.
-
Avoid wire crates in high-traffic areas—go for enclosed models that offer privacy.
Chewers and Escape Artists
If your dog is known for chewing or escaping, don’t just focus on size—think security. A metal or heavy-duty plastic kennel will keep them safe and contained. Size should still be snug enough to prevent pacing, which can increase stress levels.
Behavioral tendencies give you great insight into how your dog will react to a kennel. Choose size and structure that suits their mental needs as much as their physical dimensions.
Common Mistakes When Choosing Kennel Size
Even with all the best intentions, pet parents often overlook crucial factors when selecting a kennel. Let’s break down the most frequent mistakes and how to avoid them:
1. Going Too Big Too Soon
This is especially common with puppies. You might think you’re saving money by getting a giant kennel for your tiny pup to “grow into.” But without a divider, your dog may feel overwhelmed or start using part of the kennel as a bathroom.
2. Ignoring Breed-Specific Needs
A one-size-fits-all approach doesn’t work. A Greyhound and a Bulldog might weigh the same but have entirely different space needs due to their build and behavior. Always factor in your dog’s shape, not just their weight.
3. Forgetting Room for Accessories
If you plan to keep bedding, a water bowl, or a toy inside, you’ll need extra space. Many pet parents buy kennels that only fit the dog—then realize there’s no room left for comforts.
4. Misunderstanding the Purpose
Using a kennel for crate training? For travel? As a long-term sleep space? The function determines how precise you need to be with sizing. Travel kennels should be snug for safety, while overnight kennels can offer a bit more space for relaxation.
Avoiding these missteps ensures your dog’s kennel is not just functional but also a place they actually enjoy being in.
Accessories and Interior Space Planning
Once you've nailed the kennel size, it’s time to kit it out. But be careful—not every accessory belongs in every kennel. Planning your interior layout can enhance your dog’s comfort and make the space more functional.
Bedding
Choose bedding that’s:
-
Washable
-
Non-slip
-
Properly fitted to the floor of the kennel
Too thick and your dog might be cramped. Too thin and they won’t feel cushioned. Orthopedic beds are great for seniors.
Bowls and Feeders
Use clip-on or weighted bowls if you’re keeping food and water inside. This prevents spills and mess. Ensure there’s still room for your dog to move around comfortably.
Toys and Comfort Items
Chew toys, comfort blankets, or a favorite plush toy can help reduce anxiety. Avoid stuffing the kennel—one or two items are usually enough.
Interior planning is about balance. You want a cozy, enriching space, not clutter. Think of it as designing a mini studio apartment—for your best furry friend.
Using the Kennel for Training Purposes
Kennels play a huge role in training, especially with puppies. The size you choose affects how well your training goes.
Crate Training
The kennel should be large enough for your dog to lie down, stand, and turn—but not so large that they can soil one end and sleep in the other. This principle is what makes crate training effective for housebreaking.
Consistency is Key
Use the kennel during calm times—naps, bedtime, quiet time—not just when you're leaving the house. This helps your dog associate it with relaxation rather than punishment.
Potty Training Aid
Dogs instinctively avoid soiling their sleeping area. If your kennel is the right size, it encourages your dog to hold their bladder and reinforces potty training.
Size impacts how your dog views their kennel. If it feels too empty or overwhelming, they may not engage with it during training. The goal is to create a safe, cozy den that builds good habits.
Safety Tips When Using a Kennel
Safety should always be a top priority when kenneling your dog. Regardless of size, there are certain guidelines you should always follow:
-
Ventilation: Ensure the kennel has good airflow, especially in warmer climates.
-
Secure Locks: Dogs are smart. Use latches or locks that can’t be easily nudged open.
-
Avoid Sharp Edges: Check for any exposed wire or splinters.
-
Don’t Overcrowd: Even with multiple pets, never try to fit more than one dog in a kennel unless it’s specifically designed for cohabitation.
-
Monitor Regularly: Especially when introducing a kennel, keep an eye on your dog to ensure they’re not panicking or showing signs of distress.
Safety and size go hand in hand. A correctly sized, well-maintained kennel is the best gift you can give your pup.
Final Thoughts
Picking the right kennel size isn’t rocket science—but it does take thought, care, and a little bit of measuring tape. Your dog’s breed, behavior, and stage in life all play a part in what “perfect fit” means. A kennel that’s too small becomes a prison, and one too big can turn into a place they avoid altogether.
But when you get it right? It’s magical. You’ll see your dog cozy up, relax, and treat their kennel like their personal sanctuary.
