How often should a dog bed be washed? As a general guideline, wash the removable cover weekly to every two weeks, wash or deep clean the full bed roughly once a month, and wash sooner whenever it is visibly dirty, wet, or smelly. Replacement is a separate question that depends on the bed’s condition rather than a fixed date on the calendar.
A dog bed collects dirt, hair, drool, and skin oils faster than most people expect, simply because a dog spends hours a day in direct contact with it. This article focuses specifically on how often to wash and how often to replace a dog bed, plus a short, practical look at washing orthopedic and memory foam beds the right way, since those need a different approach than a basic stuffed bed.
Quick Answer
How often should a dog bed be washed?
- Wash the removable cover weekly to every two weeks, or sooner if it gets dirty or wet.
- Give the full bed a deeper clean roughly once a month.
- Replace the bed based on its condition, such as permanent flattening, torn seams, or lingering odor, rather than a set schedule.
How Often Should You Wash a Dog Bed?
The removable cover of a dog bed generally needs washing every one to two weeks under normal conditions, and the bed’s inner cushion or liner benefits from a more thorough clean about once a month. Dogs that spend a lot of time on their bed, shed heavily, or go outside often will land at the shorter end of that range.
A few situations call for washing sooner than any set schedule. A muddy dog that flops straight onto its bed, an accident, a bout of vomiting, or a musty smell developing between regular washes are all signs to wash right away rather than waiting for the next scheduled clean.
How Often Should You Replace a Dog Bed?
A dog bed should be replaced based on its condition, not a fixed number of months, and the clearest signals are permanent flattening that no longer bounces back, torn or fraying seams, and an odor that persists even after a proper wash. Any one of these means the bed is no longer doing its job well, regardless of how long you have owned it.
Permanent flattening matters most for support: once the foam or filling has compressed and stopped springing back, the bed is no longer cushioning your dog’s joints the way it should, which is a bigger concern for senior dogs and larger breeds. Persistent odor after washing usually means bacteria or moisture has worked its way into the padding itself, which a surface wash cannot fully reach.
Washing an Orthopedic Bed the Right Way
Start by checking the care label, since washing instructions vary by brand and by the specific foam used inside. In most cases, the outer cover on an orthopedic bed is machine washable on its own, while the foam core itself is not meant to go in a washing machine at all.
Instead of washing the foam core, spot clean it with a damp cloth and a mild, pet-safe cleaner, then let it air dry fully before putting the cover back on. Running the whole cushion, foam included, through a washing machine risks waterlogging the foam and damaging its structure, which is the single most common way owners accidentally shorten the life of an orthopedic bed.
Can Memory Foam Dog Beds Be Washed?
Memory foam itself cannot go through a washing machine. Only the removable outer cover, if the bed has one, is designed to be washed, and that distinction matters more with memory foam than with basic fiberfill because of how the material handles water.
Memory foam is dense and absorbent, so it soaks up water readily but drains and dries very slowly compared to other fillings. A foam core that gets fully saturated can stay damp at its center for days, creating ideal conditions for mold or mildew to develop inside the bed where you cannot see it, and repeated soaking can also break down the foam’s structure over time and reduce its support.
Washable and Replacement Covers
A removable, machine washable cover is one of the most useful features to look for when buying an orthopedic dog bed with a washable cover, since it lets you keep the bed genuinely clean on a normal schedule without ever risking the foam core in the wash. Beds without a separate cover force you to either spot clean the whole surface or skip deep cleaning entirely, and both options fall short over time.
Some manufacturers also sell a separate replacement cover for their orthopedic dog beds, which is worth checking for before you buy, especially if you know your dog is hard on bedding or if you would like a spare cover on hand to swap in while the other is being washed. Having two covers in rotation makes it much easier to actually stick to a weekly or biweekly wash schedule instead of putting it off because the bed would otherwise sit uncovered.
Common Mistakes to Avoid
- Putting the entire foam core in the washing machine. This is the most common cause of a ruined orthopedic or memory foam bed, since the foam absorbs far more water than it can release in a normal wash and rinse cycle.
- Drying foam on high heat. High heat can warp or break down foam, so air drying or a low, no-heat setting is the safer choice for anything foam-based.
- Ignoring a smell that returns after washing. A persistent odor after a proper wash is usually a sign the bed needs replacing, not another round in the machine.
- Waiting for a fixed date to replace a bed. Condition, not the calendar, should drive the replacement decision.
- Buying a bed with no removable cover. This makes routine washing far more difficult and often leads to less frequent cleaning than the bed actually needs.
Frequently Asked Questions
How often do dog beds need to be washed? The cover generally needs washing every one to two weeks, with a deeper clean of the full bed about once a month, adjusted for how messy or active your dog is.
How often should dog beds be replaced? Base it on condition rather than age. Permanent flattening, torn seams, and odor that survives a wash are all signs it is time for a new bed.
Can memory foam dog beds be washed? The foam itself cannot go in a washing machine. Only a removable cover, if the bed has one, should be machine washed.
Do all orthopedic dog beds have a washable cover? No, this varies by brand and model, so check the product details before buying if a washable cover matters to you.
The Bottom Line
Wash the cover every one to two weeks, deep clean the whole bed about monthly, and replace it when the condition tells you to rather than on a fixed schedule. For orthopedic and memory foam beds, keep the foam core out of the washing machine entirely and rely on a removable cover to do the heavy lifting.
