TL;DR
Wash a pet bed cover weekly and the insert about once a month, and vacuum the bed in between. Weekly is more often than most households manage, and it is the interval that keeps a bed from becoming the thing you smell when you walk in the door.
What actually builds up in a pet bed
A bed collects hair, dander, skin oils, dirt from paws, saliva, and whatever the animal rolled in outside. All of it works down into the fibers rather than staying on the surface.
That is why surface vacuuming helps but does not solve it. The odor lives in the padding, and only washing reaches it.
Beds also sit on the floor, which means they collect the household's dust and whatever the vacuum missed along the way.
How often should you wash a dog bed?
Wash the removable cover weekly, and the insert or the whole bed about monthly. Vacuum the bed two or three times a week between washes. Go to twice weekly on the cover for outdoor dogs, senior pets, animals recovering from anything, or any bed that has a noticeable smell.
A cadence by situation
| Situation | Cover | Insert or whole bed |
|---|---|---|
| Indoor pet, average | Weekly | Monthly |
| Outdoor or very active dog | Twice weekly | Every 2 to 3 weeks |
| Multiple pets sharing a bed | Twice weekly | Every 2 to 3 weeks |
| Senior pet or any incontinence | Immediately as needed | Monthly, or as needed |
| Puppy or kitten | Twice weekly | Every 2 weeks |
| Shedding season | Weekly, vacuum daily | Monthly |
| Cat bed or perch cover | Weekly | Monthly |
Vacuuming between washes is the part that makes the schedule sustainable. Two minutes with an upholstery tool removes most of the loose hair, and a bed that has been vacuumed washes far more effectively.
Read the care tag before the first wash
Pet beds vary enormously in construction, and the tag is the only reliable guide.
Removable covers usually take a normal machine wash. Check whether it says cold or warm -- many covers shrink in hot water, and a shrunken cover never goes back over the insert.
Some inserts are machine washable. Many are not, and a foam insert in particular can tear apart in a machine. Orthopedic foam beds are usually spot cleaned and air dried instead.
Waterproof liners take low heat only. High dryer heat cracks and delaminates the waterproof membrane, and once it goes the liner is decorative.
If there is no tag, treat it as cold water, gentle cycle, and air dry.
How do you wash a pet bed properly?
Vacuum it first to remove loose hair, then shake it out outdoors. Wash the cover on the cycle the tag specifies with a fragrance-free detergent, and run an extra rinse. Dry on low heat or air dry until completely dry, all the way through, before the pet uses it again.
The extra rinse matters. Detergent residue in a bed can irritate skin, and many animals are more sensitive to fragrance than people are. Fragrance-free is the safer default.
Skip fabric softener and dryer sheets entirely on pet bedding. They leave a coating, they add fragrance, and they reduce the fabric's ability to breathe.
Drying is where beds go wrong
A thick pet bed insert can feel dry on the outside while the core is still damp. A damp core develops odor within a day and can start growing things.
Give it far longer than you think it needs. Outside on a dry day is ideal. Indoors, a fan pointed at it accelerates things considerably.
Squeeze the middle of the insert before putting the cover back on. If there is any give-back of moisture, it is not done.
Having a second cover means the bed is usable while the first is in the wash, which removes the main reason people skip a week.
Never mix cleaning products
Hot water and detergent handles almost every pet bed. If you use any additional product, use one.
Never combine bleach with ammonia, vinegar, or alcohol -- those combinations release toxic gases, and pet bedding is a place where someone might reach for bleach on fabric that already carries urine ammonia.
An enzyme cleaner made for pet accidents is the better tool for urine specifically. It breaks down the compounds rather than masking them, and it works without any of the mixing risk.
Hair, and what to do about it
Wash pet bedding separately from human laundry. Hair transfers readily and ends up in every load otherwise.
Shake the bed out and vacuum it before it goes in the machine. Hair that goes into a washer ends up in the drain pump filter, and enough of it will eventually cause a problem.
Running the empty machine on a rinse cycle after a heavy pet load clears what stayed behind, and cleaning the dryer lint screen before and after is worth the extra thirty seconds.
Where the bed fits in a pet routine
The bed is the longest-cycle item of three pet zones. The other two run much shorter: how often to wash pet food and water bowls is a daily job, and in cat households how often to scoop and wash a litter box is daily too.
The pet item cleaning guide covers the whole category, and how often to clean everything in a house sets these beside every other interval in the home.
Pet hair migrates well beyond the bed, into corners, along baseboards, and into upholstery, and a home with several animals accumulates faster than a normal routine can keep up with. That is often the point where households look at house cleaning services for a reset.
Health honesty about pet bedding
Washing a bed reduces hair, dander, dirt, and odor. That is a hygiene and comfort benefit and it is worth the effort.
It does not treat, prevent, or cure anything. Skin irritation, hair loss, persistent scratching, a musty smell coming from the animal rather than the bed, or any suspicion of fleas or mites belongs with a veterinarian. Washing bedding may be part of a treatment plan a vet gives you, but it is not a treatment on its own.
FAQ
How often should you wash a dog bed?
Wash the removable cover weekly and the insert or whole bed about monthly, vacuuming two or three times a week in between. Go to twice weekly on the cover for outdoor dogs, multi-pet beds, senior animals, or any bed that has developed a noticeable smell.
Can you put a pet bed insert in the washing machine?
Some inserts are machine washable and many are not -- the care tag is the only reliable guide. Foam inserts in particular can tear apart in a machine, and orthopedic beds are usually spot cleaned and air dried instead. When there is no tag, treat it as hand wash and air dry.
What detergent should you use on pet bedding?
A fragrance-free detergent, with an extra rinse cycle to clear residue. Many animals are more sensitive to fragrance than people, and detergent left in the fabric can irritate skin. Skip fabric softener and dryer sheets entirely, since they coat fibers and add scent.
How do you get pet smell out of a bed?
Vacuum thoroughly, then wash with a fragrance-free detergent and an extra rinse, using an enzyme cleaner made for pet accidents if urine is involved. The most common reason odor returns is incomplete drying -- a thick insert can feel dry outside while the core stays damp.
Can you use bleach on a pet bed?
It is better not to. Bleach damages many fabrics and waterproof liners, and never mix it with ammonia, vinegar, or alcohol -- pet bedding often carries urine ammonia already. An enzyme cleaner formulated for pet waste handles odor more effectively with none of that risk.
How do you keep pet hair out of the washing machine?
Shake the bed out and vacuum it before washing, wash pet bedding separately from human laundry, and run an empty rinse cycle afterward. Clean the dryer lint screen before and after. Hair that gets past the drum collects in the drain pump filter over time.
How long does a pet bed take to dry?
Longer than it feels. A thick insert can be dry on the surface while the core is still damp, and a damp core develops odor within a day. Air dry outdoors on a dry day when possible, use a fan indoors, and squeeze the middle to check before reassembling.
Homes with animals accumulate hair and odor in places a routine never reaches, and what a real catch-up involves depends on the house and how long it has been. If you want an actual number rather than a general range, get a quote and we will walk you through what drives it.
