To clean a heated dog bed for winter, always unplug the bed and detach the controller completely before you touch any fabric. Remove the outer cover and wash it separately on a gentle cold cycle with a mild, pet safe detergent, then wipe the waterproof heating core with a damp cloth and let everything air dry fully before reassembly. If your dog has skin allergies, joint issues, or any diagnosed condition, check with your veterinarian before using heated features or new detergents.

The ZOMISIA Large Dog Heating Pad in XXXL 35x24 inches is a heated bed mat designed for indoor use for large dogs, cats and multi-pet households. It functions as a warming mat that fits inside beds or crates, offering extra space for stretching and lounging.
Standout features include 11 temperature levels and 25 timer settings with 24 timed options plus continuous mode. In real world use, reviewers find it easy to program, appreciate the timer for overnight use, and note the surface feels warm and even while the internal thermostat targets the set temperature.
Build quality centers on a waterproof and flame-retardant PVC core wrapped in a soft polyester fleece cover. The cover is removable and machine washable while the core wipes clean, and the power cord is chew resistant for added durability. At 0.6 inches thick and 3.06 pounds, it stays low profile and portable.
There are a few drawbacks to consider. Some owners find the lowest setting still runs warm, and the bright controller light can be noticeable in dark bedrooms. The design also requires the pet to lie over the center thermostat to activate auto shutoff, and the pad should not be folded, bent or covered during use.
Overall, this is a solid choice for pet owners who want precise control and generous sizing in a heated mat. If you need an easy to clean, customizable warming pad for a large dog or multiple pets, the ZOMISIA XXXL offers strong value and thoughtful safety features.

The INVENHO Heated Dog Bed in size M 28 x 20 inches is a low-profile electric heating pad designed for dogs, cats and small animals. It is ideal for pet owners who want consistent, adjustable warmth during colder months, especially for use inside crates, existing beds or carriers.
Its standout feature is the 11-level temperature control ranging from 80 to 130 degrees Fahrenheit, managed through an LED controller. The adjustable timer from 1 to 24 hours with auto shut-off is highly practical, and users report it heats quickly, holds temperature well and covers the full mat area evenly.
Build quality focuses on safety and practicality. The pad uses a 7-layer structure with UL-certified heating wire, an intelligent temperature sensor to help prevent overheating, and a soft PVC envelope that is waterproof and flame retardant. The power cord is protected by a spiral chew-resistant cover, and the included flannel cover is soft, zippered and machine washable.
The main drawback is comfort, as the pad itself is only about one inch thick and functions more as a heating mat than a cushioned bed. Many owners place it on top of a pillow or existing bed for extra softness. It also requires the flannel cover to be used at all times and the controller takes a moment to learn.
Overall, this is a versatile and well engineered heating pad that prioritizes adjustable warmth and safety over plush cushioning. For pet owners seeking a reliable, easy to clean warming solution that can be layered with their pet's favorite bedding, it is a strong and practical choice.
Why Heated Dog Beds Need Extra Care in Winter
Winter use means more shedding, damp paws, and body oils that settle deep into fleece. Heated beds trap warmth and moisture together, which can create odor and make the cover feel clammy if you skip regular washing.
Unlike a regular cushion, a heated bed has an electrical core, controller, and cord that can never be submerged. That is why models with a waterproof PVC layer and a removable cover, like those highlighted in our waterproof protection tips, are much easier to keep hygienic.
Heated pads also use a built in thermostat that senses pressure and temperature, so a dirty or bunched cover can interfere with even heating. Keeping the cover clean helps the sensor work as intended and keeps the surface temperature comfortable for your dog.
Step by Step: How to Clean a Heated Dog Bed Safely
Set aside 30 minutes and work on a clear floor so you can keep cords and controllers away from water. Gather a vacuum with an upholstery tool, mild fragrance free detergent, and a soft cloth before you start. These steps apply to most indoor heated pads and beds sold in 2026.
- Unplug and disassemble fully. Disconnect power at the outlet, detach the LED controller, and remove the cover via its zipper. Never pull the cord to unplug and keep the controller on a dry surface away from sinks.
- Shake out and vacuum the cover. Take the cover outside, shake off hair and debris, then vacuum with an upholstery tool. Check for stains or chewing damage and spot treat with a pet safe stain remover before washing.
- Wash the cover on gentle, cold. The INVENHO Heated Dog Bed, Waterproof Adjustable includes a super soft flannel cover with a corn kernel texture that is designed to be machine washable. Use a mild, fragrance free detergent on gentle cold, and avoid bleach or fabric softener that can irritate skin. For ideas on fabrics that hold up to frequent washing, see our guide to choosing a washable crate mat.
- Wipe the heating core, do not wash it. The inner pad on the ZOMISIA Large Dog Heating Pad, Heated Dog Bed and similar models uses a waterproof and flame retardant PVC envelope that should only be wiped with a damp cloth and mild soap. Never fold, bend, or soak the core, and never cover it while it is plugged in, as this can cause overheating.
- Dry completely before reassembling. Air dry the cover flat or tumble on low if the care label allows, and let the wiped core air dry fully. Reassemble only when both parts are completely dry, then reconnect the controller, check the cord for nicks, and place the bed flat on the floor.
Choose a fragrance free, dye free detergent labeled pet safe and use half the normal amount to reduce residue. Rinse the cover an extra time if your machine allows, since leftover detergent can irritate paws and bellies.
Never use high heat to speed drying, as it can shrink fleece and warp zippers. If you need the bed ready quickly, keep a second cover on hand so your dog always has a warm, clean place to rest.
In winter, aim to wash the cover every one to two weeks if your dog uses the bed daily, and wipe the core weekly. If your dog tracks in snow or mud, keep a spare cover so you can swap quickly while one is drying.
To control odor between washes, vacuum the cover every few days and sprinkle baking soda, let it sit 10 minutes, then vacuum again before washing. Always check the chew resistant cord cover for teeth marks, and review our chew resistant bed options if your dog is a heavy chewer.
Store the bed flat during the off season and avoid folding the heating element. Use the timer function, like the 1 to 24 hour auto shut off on both featured pads, to conserve energy and reduce overheating risk when you are away.
When to Try Something Else or Call Your Veterinarian
A heated bed is not ideal for dogs who aggressively chew cords, puppies left unsupervised, or pets with urinary incontinence that repeatedly soaks the electrical core. This setup is also not a good fit for outdoor use or for pets who tend to bunch or fold bedding, which can block the thermostat. If you notice persistent skin redness, coughing, or your dog avoids the bed, skip this style and talk to your veterinarian about alternative warming options. For non heated everyday comfort, our roundup of budget friendly washable beds offers simpler choices.
Frequently Asked Questions
Can you put a heated dog bed in the washing machine?
You can machine wash the removable outer cover, but never put the electrical heating core in the washer. Always remove the cover, wash it on gentle cold with mild detergent, and wipe the waterproof core by hand as directed in 2026 care guides.
How often should you clean a heated dog bed in winter?
For daily winter use, wash the cover every one to two weeks and wipe the core weekly, more often if your dog sheds heavily or comes in wet. Regular vacuuming between washes helps keep dander and odor under control.
What if the heated pad smells or does not heat after washing?
Make sure the cover and core are fully dry and the controller is firmly connected, and confirm the pad lies flat without folds. If odor persists or heat does not return, unplug the bed and contact the manufacturer, and consult your vet if your pet shows skin irritation.
