What Size Dog Bed Should I Get for Your Pet

Updated · 6 min read

Getting the sizing right isn't just about floor space. A bed that's too small forces a dog to sleep in a cramped position, which can exacerbate joint stiffness, especially in senior animals. Conversely, a bed that's too large might not provide the sense of security some breeds crave. Matching the bed to the specific sleeping habits and physical dimensions of your dog is the most reliable way to improve rest.

How do I accurately measure my dog for a bed?

To measure your dog accurately, you must capture their full length and width while they are in their most relaxed, extended sleeping posture.

  1. Use a soft tailor’s tape to measure from the tip of the nose to the base of the tail.
  2. Add 10 inches to that total length to account for the space required to shift positions comfortably.
  3. Measure the widest point across the shoulders or hips while the dog is lying on their side.
  4. Make sure the dog is standing or lying flat on the floor, not curled up, to avoid underestimating the necessary surface area for their frame.

What are the differences between bolster, pillow, and orthopedic bed styles?

Bolster beds feature raised edges on one or more sides, providing a sense of security and a headrest for dogs that enjoy leaning into their surroundings. Pillow beds consist of a simple, soft cushion that mimics a standard human mattress, which is excellent for dogs that change positions frequently. Orthopedic beds use high-density memory foam to distribute weight evenly, reducing pressure points for dogs with mobility issues.

While a bolster bed is ideal for a nervous dog that likes to feel tucked in, it might restrict movement for an extremely large breed that needs to sprawl. Orthopedic foam is the standard for senior dogs, but some younger, heat-sensitive breeds may find these beds too insulating. Always consider the density of the foam, as a bed that is too soft will cause a heavy dog to sink through to the floor.

Should I choose a larger bed if my dog prefers to sprawl out while sleeping?

Yes, a larger bed is necessary for sprawl-prone dogs because they require a footprint roughly 20 to 30 percent wider than their standing profile. If your dog frequently stretches their limbs fully, you should add at least 15 inches to their nose-to-tail measurement to prevent their paws from hanging off the edge.

How does a dog's sleeping position influence the ideal bed size?

A dog that sleeps on its side needs a bed that accommodates its full length plus an additional buffer for limb extension, whereas a dog that curls into a ball can utilize a smaller, circular bed. Many owners assume that a circular bed is always better for conserving space, but a dog that stretches out will eventually find a round bed restrictive and uncomfortable for its spine. If your dog shifts between curling and sprawling, prioritize the dimensions of their longest sprawl to avoid buying two separate beds.

What materials are best suited for dogs that tend to chew or dig?

Durable materials like ballistic nylon or heavy-duty canvas are the most effective choices for dogs that engage in destructive chewing or nesting behaviors.

  • Ballistic nylon provides a high-denier fabric resistance that withstands sharp claws and persistent gnawing.
  • Heavy-duty zippers must be hidden or recessed to prevent a dog from catching them with their teeth.
  • Ripstop fabrics feature a cross-hatch weaving technique that stops small tears from spreading into large holes.
  • Removable covers allow you to replace the exterior shell without discarding the internal foam or stuffing when damage occurs.

Are there specific bed size recommendations based on common dog breeds?

No, breed labels are often misleading because individual growth patterns vary significantly even within the same litter. A Greyhound, for example, requires a 45-inch bed despite its slender frame, while a stocky Bulldog of the same weight might prefer a smaller, 35-inch bed with more structural support.

How much extra space should be allowed around the perimeter of the bed for comfort?

Aim for a perimeter buffer of at least 4 to 8 inches beyond the dog's body to allow for easy entry and exit.

Bed Size TypePerimeter Buffer
Small Breeds3 - 4 inches
Medium Breeds5 - 6 inches
Large Breeds7 - 8 inches
Giant Breeds9 - 10 inches

Use these buffers as a guide to make sure the bed doesn't feel cramped against walls or furniture.

Does the age or joint health of a dog necessitate a specific type of bed support?

Senior dogs and those with joint issues require high-density memory foam or orthopedic support to prevent pressure sores and alleviate skeletal pain.

  • Arthritis symptoms often improve when a dog sleeps on a solid foam slab rather than loose fiberfill that shifts under their weight.
  • Hip dysplasia creates a need for a low-profile bed that allows the dog to step on and off without straining their joints.
  • Memory foam density should be at least 3 to 4 pounds per cubic foot to provide adequate support for heavier breeds.
  • Joint inflammation is aggravated by cold floors, so look for beds that provide at least 4 inches of lift from the ground.

What people often get wrong

  • Measuring only the dog's weight. Weight doesn't account for length or height, which are the real factors for comfort. Always use a tape measure to get the actual dimensions.
  • Ignoring the sleeping style. A dog that sprawls requires significantly more surface area than one that curls into a ball. Watch your dog for a few nights to see their preferred posture.
  • Buying for the dog's current size. Puppies grow quickly, and buying a small bed now leads to unnecessary replacements. Invest in a size that accommodates their expected adult frame.

Matching Bed Size to Sleep Habits

Observe your dog’s sleeping habits for a few days to determine if they prefer a tight, protected space or a wide-open area. Prioritize the extra length to make sure they can fully extend their limbs without touching the floor.
