Rectangle Dog Beds: Who They Suit and How to Choose One
Some dogs never curl. They lie down, stretch every leg, and take the whole bed. For them, the shape of the bed matters more than anything else about it.
Key Takeaways
- A rectangle bed suits dogs who sleep stretched out, on the side or flat on the belly, because every inch is usable resting space with no bolster in the way.
- It is the easiest shape to step onto. With no walls, a senior or short-legged dog walks straight on.
- It fits rooms and crates cleanly, squaring up against a wall, at the foot of a bed or inside a crate.
- Size by the dog stretched out, nose to tail tip with legs extended, plus a little room.
- Choose the fill by the dog: Companion-Pedic® memory foam for support under a heavier or older dog; Luxura-Fill® fiber for a plush, pillowy feel.
What is a rectangle dog bed?
A rectangle dog bed is a flat, mattress-style bed with four straight sides and no raised bolsters, so the entire top surface is resting space. It is built for dogs who sleep at full length rather than curled up, and it is the simplest shape for a dog to step onto.
Round and bolstered beds hold a curled dog in a nest. A square bed with bolsters on four sides supports a dog who leans into a corner. A rectangle does neither on purpose: it gives the long, open surface that a sprawler actually uses. Our round dog bed guide and square dog bed guide cover the other two shapes.
Which dogs do best on a rectangle bed?
Dogs who sleep stretched out, dogs who run warm and like to spread out, seniors who step rather than climb into bed, and dogs who rest in a crate. If your dog usually ends the night with legs hanging off a round bed, a rectangle is the shape to try.
| Your dog | Rectangle a good fit? | Why |
|---|---|---|
| Sleeps on the side, legs out | Yes | Every inch is usable; nothing to drape legs over |
| Older, or stiff getting up | Yes | No wall to step over; a flat, even surface |
| Sleeps in a crate | Yes | Straight sides fill the crate floor |
| Curls tight, rests the chin on an edge | Usually not | A bolstered round or square bed gives the edge they look for |
| Leans into corners | Usually not | A four-sided square bed supports them better |
What size rectangle dog bed do I need?
Measure your dog lying fully stretched out, from nose to the base of the tail with legs extended, and add a few inches each way. Choose the bed whose top surface covers that measurement. Our memory foam rectangles run from Small, 24 by 18 inches, to X-Large, 48 by 36 inches.
With no bolsters, a rectangle's outer size and its resting area are nearly the same, which makes it the easiest shape to size. When a dog falls between sizes, choose the larger: a stretched-out sleeper always uses the extra length.
Memory foam or fiber fill?
Choose memory foam for support under a heavier, older or stiff dog, and fiber for a softer, pillowy surface. Our Katie Puff® Ortho Rectangle and Ruby Puff® Ortho Rectangle are each built from 2.5 inches of CertiPUR-US® certified Companion-Pedic® memory foam. The Animal Print Floor Pillow is overstuffed with Luxura-Fill® fiber.
| Bed | Fill | Cover | Sizes | Waterproof liner option |
|---|---|---|---|---|
| Katie Puff® Ortho Rectangle | Companion-Pedic® memory foam, 2.5" | Chenille or Encore fabric | S (24" x 18") to XL (48" x 36") | Yes |
| Ruby Puff® Ortho Rectangle | Companion-Pedic® memory foam, 2.5" | Ruby faux fur, Light Gray | S (24" x 18") to XL (48" x 36") | Yes |
| Faux Fur Shag Companion-Pedic® Rectangle | Companion-Pedic® memory foam | Faux shag | S to XL | Yes |
| Animal Print Floor Pillow | Luxura-Fill® fiber | Animal-print chenille | Small to Extra Large | No |
Can a rectangle bed go in a crate?
Yes. A rectangle's straight sides fill a crate floor without the gaps a round bed leaves. Measure the inside of the crate and choose the bed size at or just under it, so the bed lies flat rather than buckling at the edges. For a dedicated crate option, read our guide to choosing a dog crate pad.
How do you care for a rectangle dog bed?
Unzip the cover and machine wash it in cold water, then hang dry, with no dryer on any setting, no bleach and no bleach alternatives. Never machine wash or soak the foam or fiber insert; spot clean it with half white vinegar and half water and let it dry fully in open air, never in a dryer. The "With Waterproof Liner" option places a Luxura-Protect™ barrier beneath the cover for occasional spills; for frequent accidents, add a waterproof blanket on top.
Frequently Asked Questions
What is a rectangle dog bed good for?
A rectangle dog bed is good for dogs who sleep stretched out, seniors who step rather than climb into bed, and crates. With no bolsters, the whole top surface is resting space and the entry is flat on every side.
Is a rectangle or round dog bed better?
It depends on how your dog sleeps. Dogs who stretch out use a rectangle's full length; dogs who curl tightly and rest the chin on an edge settle better in a round bolstered bed.
What size rectangle dog bed should I get?
Measure your dog fully stretched out and add a few inches each way, then choose the bed whose surface covers that. Our memory foam rectangles run from Small, 24 by 18 inches, to X-Large, 48 by 36 inches.
Are rectangle dog beds good for older dogs?
Often, yes. With no bolster to step over, an older dog walks straight on, and a memory foam rectangle gives an even, supportive surface. A bed is a comfort product, not a treatment; follow your veterinarian's guidance for any diagnosed condition.
Can I put a rectangle dog bed in a crate?
Yes. Measure the inside of the crate and choose the bed size at or just under it, so the bed lies flat without buckling.
