Dog Bed Types Explained: Bolster, Donut, Flat, Elevated Cot or Crate Mat

Watch how your dog sleeps for a few nights and you'll know more about which bed to buy than any product page can tell you. Curlers, sprawlers, leaners and diggers want different shapes. Add chewing, climate and how often you'll be washing it, and the choice narrows quickly. This guide covers the main styles and how to size and judge them.

Start with how your dog sleeps

Many dogs switch positions with temperature: curled when cold, sprawled when warm. If yours does, size for the sprawl.

Bed types compared

Bolster and donut beds

Bolster beds have raised, cushioned edges on some or all sides. Round "donut" or "calming" beds take this further with a deep, plush center and high round walls that many curling dogs burrow into. They're comfortable and popular, but they're mostly soft fill with limited support, which is fine for many dogs and less ideal for heavy or older ones.

About the word "calming": it describes the shape and plush texture, not a proven effect. Some dogs seem to settle well in them; others ignore them.

• Check the inner sleeping area, not just the outside dimensions; thick walls eat up space.
• A low entry on one side helps short-legged and older dogs.
• Look for a removable, zippered cover or confirm the whole bed fits your washer.
• A non-slip base stops the bed skating on hard floors.

Flat mattresses and pillow beds

A flat mattress gives a sprawler the full surface. Quality comes down to the core. Solid foam holds its shape better than loose fiber fill, which compresses and clumps over time. If support matters, look for stated foam thickness and density, and be wary of vague terms; our orthopedic dog beds guide explains what to look for in foam specs.

Pillow beds are inexpensive and comfortable at first, but loose fill flattens. They're fine for a lighter dog or a secondary spot.

Elevated cot beds

An elevated bed is a fabric or mesh surface stretched across a frame a few inches off the ground. Air flows underneath, so it stays cooler than a cushion, it doesn't hold dirt, and it can be hosed off. Many owners use them on patios, in kennels and in hot climates.

• Frame: steel or thick aluminum frames hold up best; check the stated weight capacity against your dog.
• Fabric: breathable mesh or tough woven fabric, ideally replaceable.
• Chew exposure: designs where the frame edges are tucked under the fabric give chewers less to grab.
• Comfort: some dogs find cots firm; adding a thin pad works for indoor use.

Crate mats and travel pads

A crate mat should match the crate floor closely, so it doesn't bunch up into chewable folds. Thin, washable mats are usually best; thick plush beds can take up too much headroom, and some dogs overheat on them. If your dog shreds bedding in the crate, a bare floor or a chew-resistant mat is safer than stuffing they might swallow. If they've ever eaten bedding, talk to your vet.

How to size a dog bed

1. Measure your dog sleeping in their most stretched-out position, from nose to tail tip (or to the base of the tail for curlers).
2. Add some room, roughly several inches to a foot depending on your dog's size, so they're not hanging off the edge.
3. Compare to the inner sleeping area of bolster beds, not the outer footprint.
4. Check weight limits for elevated cots and the foam thickness for heavy dogs, so they don't sink through to the floor.
5. Measure the spot where the bed will go, including space for walls on bolster beds.

Covers, cleaning and longevity

• Removable, machine-washable cover with a zipper you can hide (some dogs chew zipper pulls).
• Water-resistant liner between cover and foam for puppies, seniors and drool-heavy dogs.
• Durable fabric such as canvas or tightly woven polyester for diggers; soft plush for gentle sleepers.
• Replacement covers sold separately extend the bed's life cheaply.
• Hair-friendly fabric: smooth weaves release hair more easily than plush. Our guide to pet hair removal tools covers cleanup.

For warmth in cold months, a self-warming bed with a reflective layer is a no-power option; if you're considering an electric bed, see our guide on heated pet beds and pads.

Climate, floors and placement

Where the bed goes changes which bed makes sense. A few practical patterns:

• Warm homes or hot climates: dogs who pant or move to tile floors at night often prefer an elevated cot or a thin pad over a plush bolster. Some owners keep a cooling mat as a second option; check the product's care and chewing warnings before leaving one with a dog.
• Cold or drafty rooms: raise the bed off cold tile or concrete, place it away from doors and windows, and consider a bolster or donut that blocks drafts.
• Hard, slick floors: a non-slip base matters for older dogs who push off when standing up.
• Multiple spots: many dogs like a bed where the family spends the evening and another where they sleep at night. A good main bed plus a cheaper second mat is often better value than one premium bed in the wrong room.

Puppies and accident-prone dogs

For puppies, buy inexpensive and washable first. Puppies chew, have accidents and grow fast, so an expensive foam bed can be wasted. A crate mat or washable pillow bed through the chewing phase, then a better bed once you know your adult dog's size and habits, is the practical route. For older dogs with occasional accidents, a waterproof liner under the cover protects the foam, and a second cover lets you swap one in while the other dries.

When to replace a bed

Replace a bed when foam stays compressed where your dog lies, when fill has clumped so your dog's hips or elbows touch the floor, when the cover won't come clean, or when chewing has exposed stuffing your dog could swallow.
