A 9-year-old, 72-pound chocolate Labrador started avoiding the orthopedic bed she had loved for two years, choosing the cold kitchen tile instead. Her owner worried about arthritis pain, but on exam her joints moved well and her skin smelled faintly yeasty under the chin and paws. The bed told the story. The cover had not been washed in almost three months, the bolster seam was packed with hair, and the foam core felt damp on one side where she drooled. We stripped it that day, washed the cover on warm, aired the foam, and within four nights she was back to curling on the bed for full naps.
Shake the bed out before it ever touches water. Take it outside, unzip every removable piece, and beat the cover, liner, and insert against a rail or step. Vacuum seams, piping, and Velcro with a crevice tool. Pick off dried mud with a stiff brush. This dry step removes most hair and grit, which supports cleaner wash water and may help maintain washer drains and fabric.
Check the tag before you choose a cycle. Most covers tolerate machine washing on warm with a mild, fragrance-free detergent. Wash the cover alone or with similar pet laundry, not with heavily soiled work clothes. The Centers for Disease Control and Prevention notes that normal laundry plus thorough drying is sufficient for most household loads, with hotter water and extra care reserved for heavily soiled items.
Last spring a client with two adolescent huskies tried to save time by stuffing an entire bolster bed, waterproof liner and all, into a top-loader on hot with extra bleach. The 18-mile weekend trail routine meant the bed held sand, sap, and undercoat, and she figured hotter meant cleaner. The liner delaminated, the zipper warped, and clumped fill left a flat spot that made the younger dog circle six times before lying down. We had to replace the liner and spend two wash cycles rinsing residue that made both dogs itch. Gentle and separated would have saved the bed.

Wash in layers, not as one lump. Unzip the outer cover and wash it inside-out with zippers closed. Wash a separate waterproof liner by hand or on delicate with cold to warm water, then hang it. Spot-clean foam or fiberfill with a damp cloth and a drop of mild soap, press out moisture with towels, and air it in sun and breeze. Never soak memory foam. Rinse fully. Leftover soap supports itching more often than dirt does.
Choose soap like skin matters, because it does. Use a small amount of unscented, dye-free detergent and skip fabric softener and dryer sheets on pet bedding. For odor, add a half-cup of baking soda to the wash or white vinegar to the rinse, not both piled with detergent. Look for third-party cues such as Safer Choice when you compare labels through the U.S. Environmental Protection Agency. Honest caveat from practice: the evidence that any one “pet-safe” detergent prevents dermatitis is thin, so fragrance-free and thorough rinsing matter more than marketing words.
Dry fully or do not remake the bed. Tumble the cover on low to medium with wool dryer balls to break up clumps. Air-dry liners flat, zipper open. Stand foam on edge in moving air until no cool damp spot remains when you press hard for ten seconds. Even slight dampness supports musty odor and may help maintain yeast on skin-contact fabric.
Frequency beats deep scrubbing. Shake weekly. Wash the cover every one to two weeks, more often for droolers, allergy dogs, or post-swim season. Air the insert monthly. That cadence fits the same recovery logic as crate rest location in How to Size a Crate for Your Dog — clean, correctly sized rest space supports better sleep.
It holds up.
A 4-year-old, 38-pound border collie mix who hiked daily developed a raw hot spot on one hip after her owner doubled washing to every three days with hot water and a scented detergent plus vinegar. Over 14 nights the spot widened despite vacuuming, and the bed always smelled faintly perfumed even after drying. We pulled back to a weekly fragrance-free wash on warm, dropped the scented products, added a second cover to rotate, and kept the dog off the damp bed until it dried fully. Her scratching eased, and the owner kept the spare-cover rotation because it fit a busy training schedule better than constant washing, much like rotating load on Should Your Dog Carry Its Own Backpack?.
Bend the routine for incontinence, surgery, and parasites. Use a waterproof liner plus a washable pee pad on top for seniors or post-operative dogs. Wash soiled pads promptly on warm with an extra rinse, and clean the machine drum after a flea or mange bedding load. Replace lumpy fill or cracked liners rather than fighting them. Prevention here is simple home care: dry paws before bedtime, brush loose coat outside, and keep the bed off cold concrete where condensation collects.
Frequently asked questions
How often should I wash a washable dog bed?
Shake it weekly and wash the outer cover every 1–2 weeks, more often for heavy drool, allergies, swimming, or senior incontinence. Air the insert monthly and always dry fully before use.
Can I put foam inserts in the washing machine?
In most cases, no. Wash removable covers and liners per the tag, spot-clean foam with a damp cloth and mild soap, press out moisture, and air-dry on edge until completely dry.
