How Big a Dog Bed Do I Need? The Ultimate Sizing Guide for Every Breed

Finding the perfect dog bed size can feel like a puzzle – too small and your pup hangs off the edges too large and they might feel insecure. I’ve been there with my own dog, going through multiple beds before finding the right fit. Using the right measurements makes all the difference between a bed your dog loves and one they ignore.

Why Dog Bed Size Really Matters

When I first got my dog, I didn’t realize how important bed size was. A bed that’s too small can cause

• Sore joints from insufficient support
• Muscle pain from cramped sleeping positions
• Disrupted sleep patterns
• Hip and back problems (especially in larger breeds)

The right sized bed gives your furry friend the comfort they need for quality rest and joint health

How to Measure Your Dog for the Perfect Bed

Unlike human beds with standard sizes, dog beds vary widely between manufacturers. Here’s the foolproof way to measure your dog:

1. Measure length: With your dog standing, measure from the tip of their nose to the base of their tail (not the tip of the tail).

2. Measure width: Measure your dog from shoulder to shoulder at the widest point.

3. Add extra space: Add 6-12 inches to both measurements to give your dog room to stretch and move.

Most pet parents are surprised to discover they’ve been underestimating their dog’s space needs after proper measuring!

Dog Bed Size Chart by Weight and Breed

Here’s a comprehensive guide to help you choose based on your dog’s size:

Consider Your Dog’s Sleeping Style

Dogs have different sleep preferences, which should influence your bed choice:

Curlers

Many dogs instinctively curl up in a ball when sleeping. This sleeping position provides warmth and a sense of security. For these dogs, a round or oval bed with raised edges works well, and they typically don’t need as much surface area.

Sprawlers

If your dog likes to stretch out completely when sleeping, you’ll need a larger, rectangular bed with plenty of room. These dogs use the entire surface of the bed and often hang their limbs off the edge if there’s not enough space.

Leaners

Some dogs prefer to sleep while leaning against something. These pups might benefit from bolster beds that have raised edges to lean against. My friend’s Boxer always sleeps with his back pressed against something!

Burrowers

Burrowers like to dig and nest before settling down, often preferring to sleep under covers. These dogs might enjoy cave-style beds or beds with hoods that create a den-like atmosphere.

Types of Dog Beds and Sizing Considerations

Different bed styles might require different sizing approaches:

Orthopedic Dog Beds

These beds use memory foam or other supportive materials to cushion joints. For older dogs or those with arthritis, I’d recommend sizing up slightly to give them more room to find a comfortable position.

Round or Oval Beds

Perfect for dogs that curl up when sleeping. For round beds, measure the diameter:

• Small (20″ / 50 cm): Suitable for dogs up to 5 kg
• Medium (30″ / 76 cm): Good for dogs up to 15 kg
• Large (40″ / 101 cm): Works for dogs up to 30 kg
• X-Large (50″ / 127 cm): Best for dogs over 30 kg

Rectangular Pillow Beds

Great for sprawlers who stretch out. Use the length and width measurements from our size chart, and make sure there’s enough space for your dog to fully extend.

Bolster Beds

These sofa-style beds have raised edges. When sizing, remember that the bolsters take up some of the usable sleeping space, so you might need to go up a size compared to a flat bed.

Covered or Cave Beds

These provide security for burrowers. Make sure your dog can turn around comfortably inside the cave portion – the interior dimensions are what matter most here.

Real-World Examples for Common Breeds

Let me share some specific examples based on my experience:

• For a 20kg dog (like a Beagle or Cocker Spaniel), you’ll want a medium to large bed, around 36 inches (91 cm) in length for a rectangular bed or a 40-inch (101 cm) diameter for a round bed.

• My neighbor’s Labrador Retriever (35kg) sleeps comfortably on an X-Large bed measuring 44″×32″ (112×81 cm), which gives him plenty of room to stretch.

• For tiny breeds like Chihuahuas or Yorkshire Terriers, a small bed around 18″×24″ (46×61 cm) provides ample space while still feeling cozy and secure.

Special Considerations

Growing Puppies

If your dog is still growing, sizing up is smart. You can make a slightly-too-big bed more comfortable by adding blankets or towels until they grow into it. I made the mistake of buying a “puppy-sized” bed for my Lab mix, only to replace it two months later!

Senior Dogs

Older dogs often need more cushioning and support. An orthopedic bed with memory foam can help relieve pressure on aging joints. Some seniors also prefer more space to adjust positions comfortably throughout the night.

Multi-Dog Households

If your dogs sometimes share a bed, size up accordingly. Even if they usually sleep separately, having a larger option available can be nice for those cuddle sessions.

Bed Material and Maintenance Considerations

The size isn’t the only thing that matters – materials affect comfort and cleaning too:

Fill Material

Memory foam beds are excellent for support but usually come in standard sizes. Loose fill beds (with foam shreds or pellets) may flatten over time, effectively reducing the usable size of the bed. My first dog bed with loose fill shrank to half its original size after just a few months!

Washability

Larger beds can be challenging to clean. For XL and XXL beds, check if they’ll fit in your washing machine or if you’ll need to take them to a laundromat. Beds with removable, washable covers are ideal for larger sizes.

Common Mistakes to Avoid

1. Underestimating size needs: When in doubt, go bigger! Dogs appreciate having space to stretch and adjust.

2. Ignoring sleeping style: A bed that’s technically the right size but wrong style won’t get used.

3. Focusing only on cuteness: That adorable tiny bed might look perfect in your decor, but if it’s too small for your dog, it’s a waste of money.

4. Not measuring properly: Don’t guess – actually measure your dog while they’re standing.

FAQ: Common Dog Bed Sizing Questions

Q: What size bed does a 20kg dog need?
A: A 20kg dog typically needs a medium to large bed. Look for dimensions around 36″×25″ (91×64 cm) for rectangular beds or a 40″ (101 cm) diameter for round beds.

Q: Should I size up if my dog is still growing?
A: Yes! It’s better to get a slightly larger bed that your puppy can grow into. You can make it cozier with blankets until they reach full size.

Q: Is a flat or bolstered bed better for joint issues?
A: Dogs with joint problems often do best with flat orthopedic beds with memory foam for even support. However, some prefer bolsters for resting their head while keeping their body on the supportive surface.

Q: What’s the difference between inches and centimeters in bed sizing?
A: They’re just different measurement units. For reference:

• 24 inches = about 61 cm
• 36 inches = about 91 cm
• 48 inches = about 122 cm

Final Thoughts

Finding the perfect sized dog bed might take some trial and error, but starting with accurate measurements gives you the best chance of success. Remember that dogs, like humans, have personal preferences when it comes to sleep. Watch how your dog naturally positions themselves when sleeping and use that as a guide.

I’ve found that investing in a quality, properly-sized bed pays off in the long run – both for your dog’s comfort and your wallet, since you won’t need to keep replacing unsuitable beds.
