Disinfecting pet bedding is the process of eliminating bacteria, viruses, parasites, and odors from your dog or cat’s sleeping area using heat, steam, or pet-safe disinfectants. In our house with two dogs and a rescue cat, I wash bedding every week, and the difference in smell and coat condition is immediate. This guide covers the full process I use, plus what veterinarians and pet-care forums recommend for keeping pet bedding truly sanitary in 2026.

Why Disinfecting Pet Bedding Matters for Health?
Pet bedding is a magnet for biological buildup. Hair, dander, saliva, urine, and outdoor dirt accumulate faster than most owners realize. Over time, this creates a breeding ground for bacteria, fungi, and parasites that can affect both pets and people.
Common pathogens found on unwashed pet bedding include Salmonella, Staphylococcus aureus, and Leptospirosis, all of which are zoonotic, meaning they can pass from animals to humans. Dust mites and flea eggs also thrive in fabric that isn’t regularly cleaned. The American Kennel Club notes that even healthy-looking beds can harbor allergens strong enough to trigger asthma and skin flare-ups in sensitive family members.
Regular disinfection reduces these risks dramatically. It also keeps your home smelling fresher and extends the life of the bed itself. Think of it as preventive medicine: a few minutes of weekly care saves vet visits later.
How Often Should You Disinfect Pet Bedding?
The right cleaning frequency depends on your pet’s lifestyle and health. A healthy indoor cat needs less frequent washing than a dog that rolls in the yard every afternoon. Below is a quick-reference guide I use with our pets.
| Pet Type / Situation | Recommended Wash Frequency |
|---|---|
| Healthy indoor dog | Every 1 to 2 weeks |
| Outdoor or active dog | Every 5 to 7 days |
| Puppies, seniors, or sick pets | Every 2 to 3 days |
| Indoor cat | Every 2 weeks |
| Multi-pet households | Weekly minimum |
| After illness, fleas, or accidents | Immediately, then repeat in 3 days |
When in doubt, go more often rather than less. Pets that sleep on the bed with you, or that share sleeping spots with children, should follow the more frequent schedule. I rotate two sets of bedding for each of our dogs so a clean one is always ready.
Step-by-Step: How to Disinfect Pet Bedding in the Washing Machine
Most pet beds with removable covers can be disinfected in a standard washing machine. The key is preparation, water temperature, and proper drying. Here’s the exact process our team follows.
Step 1: Remove Excess Hair and Debris
Take the bed outside and shake it vigorously to release loose hair and dirt. Then run a vacuum with an upholstery attachment over every surface, including seams and corners. Skipping this step means pet hair will clog your machine’s filter and redeposit on the fabric.
Pro tip from Reddit’s r/laundry community: run the bed through a 10-minute air-only dryer cycle before washing. The tumbling action loosens hair that vacuuming misses, and you can clean it out of the lint trap afterward.
Step 2: Pre-Treat Stains and Odors
Spray any urine, vomit, or muddy spots with an enzyme-based pet stain remover. Let it sit for 10 to 15 minutes so the enzymes can break down the organic matter. For tough odors, sprinkle baking soda directly on the affected area and gently work it in.
Step 3: Use Hot Water and Pet-Safe Detergent
Wash pet bedding in hot water, ideally 130F (54C) or higher, to kill bacteria, dust mites, and flea eggs. Use a fragrance-free, pet-safe laundry detergent. Avoid fabric softeners and bleach unless the fabric care label allows them, as residues can irritate pet skin.
For an extra disinfecting boost, add half a cup of white vinegar to the rinse cycle. Vinegar helps neutralize odors and acts as a natural fabric softener without leaving a harmful residue.
Step 4: Dry Thoroughly
Run the bed through a full dryer cycle on low or medium heat. High heat can warp stuffing or damage waterproof liners. Make sure the bed is completely dry before returning it to your pet, because any residual moisture can trigger mold growth and reattract bacteria.
If the bed is too large for your dryer, hang it outside on a sunny day. UV sunlight is a natural disinfectant and will help kill remaining germs while removing any lingering smell.
Natural Disinfectants: Vinegar, Baking Soda, and Enzyme Cleaners
Not everyone wants to use harsh chemicals around their pets. Several natural options work well for routine disinfection and are safe when used correctly.
White vinegar is one of the most popular choices. Its acetic acid content kills many common bacteria and neutralizes odors. Add one cup to the rinse cycle or mix equal parts vinegar and water in a spray bottle for spot-treating. Despite the smell during application, vinegar odor dissipates fully once dry.
Baking soda is another gentle workhorse. It deodorizes fabric, lifts light stains, and is safe for pets. Sprinkle it generously on the bed before vacuuming, or add half a cup directly to the wash drum. Combining baking soda with vinegar creates a fizzing reaction that helps release trapped debris.
Enzyme cleaners are the gold standard for biological stains and odors. They contain beneficial bacteria that break down urine, saliva, and other organic matter at a molecular level. Brands like Nature’s Miracle are widely recommended by veterinarians and forum users for their effectiveness on pet messes.
For households with pets that lick or chew bedding, these natural options offer peace of mind. Just remember that “natural” doesn’t always mean stronger; for serious disinfection after illness or parasites, hot water remains essential.
How to Disinfect Pet Bedding Without Washing It?
Some beds can’t go in the washing machine: orthopedic foam beds, large bolster beds, or beds with delicate fills. For these, alternative disinfection methods work well.
Steam cleaning is my go-to method for non-washable beds. A handheld garment steamer or steam mop held a few inches from the fabric kills bacteria, dust mites, and flea eggs on contact. Work slowly across every surface, and let the bed air dry completely afterward.
For a quick refresh between deep cleans, vacuum the bed thoroughly and then lightly mist it with a diluted white vinegar solution (one part vinegar to three parts water). Allow it to air dry in direct sunlight if possible. The UV exposure adds another layer of disinfection.
Baking soda also works wonders for non-washable beds. Sprinkle it liberally, let it sit for 30 minutes, then vacuum it off. This pulls odors out of the fabric and leaves the bed smelling fresh.
Removing Fleas, Ticks, and Parasites During Washing
If your pet has had fleas, the bedding must be treated the same time you treat the animal. Otherwise, eggs and larvae in the fabric will simply reinfest your pet within days.
Wash all bedding in hot water, 130F (54C) or higher, with your regular pet-safe detergent. The high heat kills adult fleas, larvae, and most eggs. After washing, dry on the highest heat setting the fabric allows for at least 30 minutes. Heat is what finishes the job; cold or warm water alone won’t eliminate an infestation.
For heavily infested bedding, sprinkle food-grade diatomaceous earth on the dry fabric before washing. Let it sit for an hour, then vacuum. The powder dehydrates flea eggs and larvae. Repeat the wash-and-dry cycle two or three times over the next week to catch any newly hatched fleas.
Don’t forget to treat the surrounding area. Wash any blankets, rugs, or soft toys your pet has touched. Vacuum carpets and upholstery thoroughly, and empty the vacuum canister outside to prevent reinfestation.
Dealing with Urine Stains and Stubborn Odors
Urine is one of the toughest challenges in pet bedding care. It penetrates deep into stuffing, and if not treated properly, the smell returns every time your pet lies down, often encouraging repeat accidents.
Start by blotting fresh urine with paper towels, pressing firmly to absorb as much liquid as possible. Avoid rubbing, which pushes urine deeper into the fabric. Once blotted, apply an enzymatic cleaner generously, making sure to soak all affected layers.
For beds with removable covers, take the cover off and check the inner lining. Urine often soaks through to the foam or stuffing. If the inner fill smells strongly after washing, it may need to be replaced.
Never use ammonia-based cleaners on pet stains. Ammonia smells similar to urine and can actually encourage your pet to mark the same spot again. Stick with enzyme cleaners or a vinegar-water solution.
Beds Without Removable Covers and Oversized Beds
Large or non-removable beds require a different approach. The bathtub method works well for these.
Fill a bathtub with hot water and add a small amount of pet-safe detergent. Submerge the entire bed and let it soak for 15 to 20 minutes, gently pressing the fabric to release trapped dirt. Drain the tub, then press out excess water without wringing, which can damage the filling.
Refill the tub with clean water and a half cup of vinegar for a final rinse. Drain again and press out as much moisture as possible. Dry the bed on a sunny deck or in a commercial-sized dryer at a laundromat if your home dryer is too small.
For oversized or heavy beds, a commercial laundromat with large-capacity washers and dryers is often the most practical solution. Many pet owners use these monthly for thorough disinfection.
Between-Wash Maintenance and When to Replace Bedding
Daily maintenance keeps bedding fresher between full washes and reduces how often deep cleaning is needed.
Run a quick vacuum over the bed every day or two to pick up hair and dander. This takes less than a minute and prevents buildup that attracts bacteria. Sprinkling a thin layer of baking soda once a week and vacuuming it off after 20 minutes also helps control odors.
Even with good care, pet bedding doesn’t last forever. Replace the bed when you notice flattened stuffing that no longer supports your pet, persistent odors that survive washing, tears or exposed stuffing, or after a major illness or parasite infestation. A general rule: replace every 1 to 3 years depending on use.
Machine Maintenance After Pet Laundry
Washing pet bedding in the same machine you use for human laundry is sanitary as long as you clean the machine afterward. Pet hair, dander, and bacteria can linger in the drum, filter, and seals.
After each pet load, run an empty hot-water cycle with a cup of white vinegar or a washing machine cleaner. Wipe down the rubber door seal and clean the lint trap. If your machine has a pet-hair filter, rinse it thoroughly.
Some owners prefer to keep pet laundry completely separate from human clothing, and that’s a personal choice. Both approaches work as long as you sanitize the machine regularly.
Frequently Asked Questions
How do you disinfect bedding without washing it?
Use a handheld steamer, a diluted white vinegar spray (1:3 with water), or sprinkle baking soda, let sit 30 minutes, then vacuum. Direct sunlight also helps kill bacteria with UV light.
Can you spray Lysol on dog bedding?
It’s best to avoid Lysol and other phenol-based disinfectants on dog bedding. Dogs can react to phenols and strong fumes. Use pet-safe alternatives like diluted vinegar or steam instead.
How do you wash pet bedding to get rid of fleas?
Wash in hot water at 130F or higher with pet-safe detergent, then dry on the highest heat the fabric allows for at least 30 minutes. Repeat in 5 to 7 days to catch any newly hatched fleas.
How often should you wash your pet’s bedding?
Healthy indoor pets should have bedding washed every 1 to 2 weeks. Outdoor pets, puppies, seniors, and multi-pet households need washing weekly. Sick pets or those with parasites need immediate washing.
Can I spray vinegar on a dog bed?
Yes. A 1:1 or 1:2 dilution of white vinegar and water is safe on most dog bed fabrics. It helps neutralize odors and kills many common bacteria. The vinegar smell disappears once dry.
Is it sanitary to put dog bed covers in my washer?
Yes, as long as you clean the machine afterward with an empty hot cycle and wipe the seal. Many owners keep pet laundry separate from human clothing as a precaution.
