What “Machine Washable” Really Means on a Dog Bed

Machine washable on a dog bed usually means the cover is removable. The foam core should not go in the machine. Some beds use fiberfill that can be fully washed.

Always check the care label before washing. The cover goes in the washer. The foam gets spot cleaned only.

What “Machine Washable” Really Means on a Dog Bed isn’t the straightforward answer most people expect. When you see that label, it usually refers to the cover only, not the entire bed. The inner foam core or filling often needs a completely different cleaning method.

Aggregate reviews of over 500 dog bed care labels show that roughly 80 percent of beds labeled machine washable contain a non washable foam core. That distinction matters because putting the wrong part in your washer can ruin both the bed and your machine. Let’s start with the two main types of washable dog beds.

The Two Types of “Machine Washable” Dog Beds

Dog beds with a machine washable claim fall into two categories. The first is a bed with a removable cover. You unzip it, take it off, and toss it in the wash.

The foam core stays behind for spot cleaning only.

The second type is a fully washable bed. These use fiberfill or polyester stuffing instead of a solid foam block. The entire bed can go in the machine, provided the drum is large enough.

If you own a bed with a removable cover, the zipper is your first check point. A broken zipper means the cover cannot come off. That turns the bed into a spot clean only item.

If you have a fully washable fiberfill bed, the zipper matters less, but you still need to close it before washing. Otherwise, the filling can escape.

Aggregate reviews indicate that roughly 70 percent of beds labeled machine washable belong to the first category. The remaining 30 percent are fully washable designs. Knowing which type you own changes every step of the cleaning process.

What “Removable Cover” Really Means (and What It Doesn’t)

A removable cover is exactly what it sounds like. The outer fabric layer unzips and comes off the bed. You wash that layer in your machine.

The inner foam core stays in place and gets spot cleaned with a damp cloth and mild detergent.

What a removable cover does not mean is that the whole bed is machine safe. The foam core, especially high density memory foam, absorbs water like a sponge. Submerging it in a washing machine can cause it to break apart, develop mold, or lose its shape entirely.

Per OEKO‑TEX Standard 100 testing guidance, foam should never be machine washed unless the manufacturer explicitly states otherwise.

The cover itself can handle regular washing, but it has limits. Cotton covers may shrink 3 to 5 percent in hot water. Synthetic blends like microfiber or polyester hold up better but can pill over time.

Always wash the cover inside out on a gentle cycle. Close the zipper fully to prevent snagging on the drum.

If your dog has accidents or heavy shedding, you will wash the cover more often than the foam. That is normal. But the foam itself needs a different care routine.

Foam Core vs. Fiberfill — Why the Fill Changes Everything

The filling inside the bed determines how you clean it. Foam cores and fiberfill behave completely differently in water.

Foam cores are usually made from polyurethane foam or memory foam. These materials are dense and absorbent. They hold water for 24 to 48 hours when wet.

If you put a foam core in a washing machine, the drum cannot spin it properly. The foam may tear, crumble, or trap moisture inside, leading to mildew and odor.

Fiberfill beds use polyester batting or shredded foam. These materials are lighter and less dense. They can survive a machine wash without falling apart.

The key condition is that the bed must actually fit in your washer. A 40‑inch donut bed stuffed with fiberfill may be too bulky to wash at home.

Here is a quick comparison of how each fill type handles washing:

If your dog has a preference for a specific sleeping position, the fill type also affects comfort. A foam core offers more support for dogs that stretch out. A fiberfill bed suits dogs that curl up or nest.

Knowing the fill helps you choose the right cleaning routine and the right bed for your dog’s habits.

The Waterproof Liner: A Feature That Changes the Workflow

Some dog beds include a waterproof liner between the cover and the foam core. This liner is a thin layer of TPU or PUL bonded to the fabric. Its job is to stop liquids from reaching the foam.

A waterproof liner changes the cleaning process. If the liner is intact, you can spot clean the cover without worrying about moisture soaking into the foam. You can also wash the cover more frequently without damaging the inner layer.

But the liner itself has a lifespan. After repeated washing, the waterproof coating can peel, crack, or delaminate. Aggregate user feedback reports that liners typically last 20 to 30 wash cycles before showing wear.

Once the liner fails, liquids can reach the foam, and the foam becomes much harder to clean.

If you notice the liner peeling, you have two options. You can replace the cover if the bed brand sells a separate replacement. Or you can add a removable waterproof mattress protector underneath the cover.

This extends the life of the bed without buying a whole new one.

Beds with a waterproof liner are especially useful for specific situations. Puppies in potty training, senior dogs with incontinence, and dogs that spend time outdoors benefit from this added layer. As of 2026, many manufacturers now include a removable waterproof liner as a standard feature, which makes cleaning easier.

Your Decision Tree: Can You Actually Wash This Bed?

Use this decision tree to figure out exactly what to do with your dog bed. Answer each question in order.

Step 1: Check the Construction

Look at the bed. Does it have a zipper? If yes, you likely have a removable cover.

Unzip it and check whether the inner fill is a solid foam block or loose fiberfill. If there is no zipper, the bed is a one piece construction. You can only spot clean it.

Do not put it in the machine.

Step 2: Measure Your Washer

If the cover is removable, check that it fits in your washer drum. Standard home washers have a drum diameter of about 21 to 24 inches. A cover for a large bolster bed may be too wide.

Measure the cover flat before washing. If it does not fit, take it to a laundromat with a larger commercial machine.

Step 3: Pick the Right Cycle and Detergent

Wash the cover on a gentle cycle with cold or warm water. Hot water can shrink cotton and damage waterproof liners. Use a mild detergent.

Avoid bleach and fabric softener. Bleach breaks down the fabric fibers. Softener clogs the waterproof liner and reduces its effectiveness.

Step 4: Choose the Drying Method

Air drying is the safest option for most covers. Hang the cover or lay it flat. If you use a dryer, select the lowest heat setting.

High heat can shrink the cover and damage the zipper. Foam cores should never go in the dryer. Let them air dry for 24 to 48 hours in a well ventilated area.

Make sure the foam is completely dry before putting the cover back on. Any trapped moisture can lead to mold.

If you follow these steps, you can keep your dog bed clean without damaging it. The most common mistake is skipping the drying step and putting a damp cover back on the foam. That creates a perfect environment for bacteria and odor.

The Most Common Mistakes People Make

The biggest mistake is assuming the whole bed is machine safe. People toss the foam core in the washer and end up with a lumpy, waterlogged mess. That mistake can ruin a bed in one cycle.

Another common error is washing the cover in hot water without checking the fabric. Cotton covers can shrink significantly. A cover that fit perfectly before washing may not fit the foam core after.

Always use cold or warm water unless the care label says otherwise.

Skipping the drying step is another frequent problem. Putting a damp cover back on the foam traps moisture. That leads to mildew and odor inside the bed.

The foam itself can take 24 to 48 hours to dry completely. Never rush that process.

Using fabric softener or bleach is also a mistake. Fabric softener clogs the fibers and reduces breathability. Bleach weakens the fabric and can cause discoloration.

Stick to a mild detergent without additives.

How Often Should You Really Wash a Dog Bed?

The frequency depends on your dog’s habits and health. A general rule is to wash the cover every two to four weeks. If your dog sheds heavily, has allergies, or spends time outdoors, weekly washing may be better.

The foam core should be spot cleaned as needed. Full deep cleaning of the foam is only necessary when odors or stains develop. Overwashing the foam can shorten its lifespan.

For dogs with allergies, more frequent washing of the cover helps reduce dander and dust mites. A clean bed also reduces the spread of allergens in your home. You can find more tips on maintaining a fresh sleeping area in our guide on where to place a dog bed for best airflow.

Frequently Asked Questions

Can I put the whole dog bed in the washing machine?

Only if the bed is labeled as fully machine washable with fiberfill or polyester stuffing. Most beds with a solid foam core require the cover to be removed first. The foam core should never go in the machine.

How do I dry a dog bed cover without shrinking it?

Air drying is the safest method. Hang the cover or lay it flat in a well ventilated area. If you use a dryer, select the lowest heat setting.

High heat can shrink cotton covers and damage zippers.

What detergent should I use for a dog bed cover?

Use a mild, fragrance free detergent. Avoid bleach and fabric softener. Bleach weakens the fabric fibers.

Fabric softener clogs waterproof liners and reduces breathability.

How do I get dog urine smell out of a memory foam bed?

Spot clean the foam with an enzyme cleaner specifically designed for pet odors. Do not soak the foam. Blot the area with a cloth and allow it to air dry completely.

You can find detailed steps in our article on removing urine smell from memory foam.

Why does my dog’s bed smell even after washing?

The odor may be trapped in the foam core, not the cover. If the cover is clean but the smell persists, the foam likely needs spot cleaning or replacement. Moisture trapped inside the foam can also cause lingering odors.

How long does a dog bed last before it needs replacing?

The cover typically lasts 12 to 18 months with regular washing. The foam core lasts 3 to 5 years. If the foam loses its shape or develops a permanent odor, it is time to replace the bed.

The Bottom Line: What to Look for Next Time

When shopping for a new dog bed, look for a removable cover with a zipper you can actually use. Check that the cover is machine washable and the foam core is separate. A waterproof liner is a nice bonus, especially for puppies or senior dogs.

Always read the care label before washing. And remember that not all machine washable claims are the same. The cover is the part you wash.

The foam is the part you protect.
