How To Wash A Dog Harness In A Washing Machine
Dog harnesses get dirty.
Between everyday walks, muddy paws, rain, grass, dog hair, and the occasional roll in something we'd rather not identify, even the cutest harness eventually needs a wash.
The good news? Many dog harnesses can be washed in a washing machine—as long as the manufacturer says the harness is machine washable.
The basic process is simple: fasten the buckles, place the harness inside a mesh laundry bag, wash it on a gentle cycle with cool water and mild detergent, then lay it flat to air dry completely.
No dryer.
That last part matters.
Can you put a dog harness in the washing machine?
Sometimes.
Before putting any dog harness in the washing machine, check the manufacturer's care instructions.
The material and construction of the harness determine whether machine washing is appropriate.
Many synthetic fabric harnesses can tolerate a gentle machine wash, while harnesses containing materials like leather or certain specialty components may need to be cleaned by hand.
When in doubt, follow the label.
Your washing machine is not the ideal place for experimentation.
How to wash a dog harness in a washing machine
If the care instructions say your harness is machine washable, here's how to do it.
1. Remove loose dirt and dog hair
Give the harness a good shake before putting it in the washer.
Brush away dried mud, grass, and excess dog hair. A soft brush or old toothbrush can help loosen dirt around seams and hardware.
For heavily soiled spots, gently pre-treat them according to the harness manufacturer's instructions.
2. Fasten the buckles
Close the harness buckles and secure any loose straps before washing.
This helps prevent straps from becoming tangled and keeps loose hardware from moving around as much during the wash.
3. Put the harness in a mesh laundry bag
Place the entire harness inside a zippered mesh laundry bag.
This protects the harness from getting tangled around other items while also helping prevent buckles and hardware from repeatedly hitting the inside of your washing machine.
Maytag specifically recommends using a mesh garment bag when machine washing a harness.
No laundry bag?
A securely closed pillowcase can work in a pinch.
4. Use cool water and a gentle cycle
Choose your washing machine's gentle or delicate cycle and use cool or cold water unless the manufacturer's instructions specify otherwise.
Avoid unnecessarily hot water, which can be harder on certain fabrics, padding, coatings, plastic components, and hardware.
Gentle is the name of the game here.
We're cleaning the harness.
Not punishing it for being dirty.
5. Use a small amount of mild detergent
Use a mild detergent and avoid harsh cleaning products unless the harness manufacturer specifically says they're safe.
Skip bleach.
It's also a good idea to avoid heavily fragranced products, especially on something that will sit directly against your dog's body.
And don't assume more detergent means a cleaner harness.
You want the detergent to rinse completely out of the material.
6. Remove it promptly after washing
Once the cycle finishes, take the harness out of the laundry bag.
Check the straps and padding and gently reshape anything that became folded during washing.
This is also a good opportunity to inspect the harness.
Look for fraying, loose stitching, cracks in plastic buckles, damaged hardware, or anything else that could affect how securely it functions.
How should you dry a dog harness after washing?
Lay the harness flat to air dry completely.
Do not put it in the dryer unless the manufacturer explicitly says you can.
Heat can potentially affect webbing, padding, elastic, plastic components, coatings, stitching, or other materials used in the harness.
Maytag's pet-laundry guidance specifically recommends that dog collars and harnesses be laid flat to air dry after washing.
Lay the harness flat in a well-ventilated area and allow all layers to dry completely before putting it back on your dog.
Thicker padded or mesh harnesses may take longer than they appear to from the outside.
If the inside is still damp, it isn't done.
Dog harness washing guide at a glance
The care label always wins, but this is a good general starting point for a machine-washable harness.
| Washing step | What to do | What to avoid |
|---|---|---|
| Before washing | Remove loose dirt and fasten buckles | Putting a muddy, tangled harness straight into the washer |
| Protect the harness | Place it inside a mesh laundry bag | Letting straps and hardware tumble loose |
| Wash | Use cool water and a gentle cycle | Hot water or aggressive wash cycles unless specifically allowed |
| Detergent | Use a small amount of mild detergent | Bleach and harsh cleaning products |
| Dry | Lay flat to air dry completely | Putting the harness in the dryer |
Easy enough.
The biggest mistake is usually not the washing part.
It's getting impatient with the drying part.
How often should you wash a dog harness?
There's no universal schedule.
Wash it when it needs it.
A dog who wears a harness for short neighborhood walks may need theirs washed far less frequently than a dog who swims, hikes, rolls in grass, or spends half their life attempting to become one with the mud.
In between full washes, spot cleaning can help remove small areas of dirt without washing the entire harness every time.
And smell is generally a pretty effective notification system.
Can all dog harnesses go in the washing machine?
No.
The safest answer is always to check the care instructions for the specific harness.
Materials, padding, hardware, decorative elements, coatings, and construction can all affect whether machine washing is appropriate.
Leather harnesses, for example, generally shouldn't be put in a washing machine. Structured or specialty harnesses may have their own care requirements too.
If the manufacturer says hand wash only, hand wash it.
The washing machine does not get a vote.
The practical next step
Check the label on your harness first.
If it's machine washable:
Fasten it.
Bag it.
Wash it gently.
Then lay it flat and let it air dry completely.
That's really it.
And while the harness is clean and off your dog, take 30 seconds to inspect the straps, stitching, buckles, and leash attachment points.

A clean harness is good.
A clean harness that actually fits correctly is considerably better.
Frequently asked questions
Can I wash my dog's harness in the washing machine?
Many dog harnesses can be machine washed, but it depends on the material and construction. Always check the manufacturer's care instructions first. If machine washing is allowed, use a mesh laundry bag, cool water, a gentle cycle, and mild detergent.
What setting should I use to wash a dog harness?
For a machine-washable harness, a gentle or delicate cycle with cool or cold water is generally the safest choice unless the manufacturer's instructions specify something different.
Should I put a dog harness in a laundry bag?
Yes. A mesh laundry bag helps prevent straps from tangling and keeps buckles and other hardware from repeatedly hitting the inside of the washing machine.
Can I put a dog harness in the dryer?
Unless the manufacturer specifically says the harness is dryer-safe, skip the dryer. Lay the harness flat to air dry completely instead. Heat can damage or alter some of the materials used in harness construction.
How long does a dog harness take to air dry?
Drying time depends on the material, thickness, padding, humidity, and airflow. A lightweight harness may dry relatively quickly, while a thick padded or mesh harness can take considerably longer. Don't put the harness back on your dog until every layer is completely dry.
What detergent should I use to wash a dog harness?
Use a small amount of mild detergent unless the manufacturer's care instructions recommend something specific. Avoid bleach and harsh cleaning products, and make sure the detergent rinses completely out of the harness.
How often should I wash my dog's harness?
Wash it as needed based on how often your dog wears it and how dirty it gets. Dogs that swim, hike, play in mud, or wear their harness daily may need more frequent cleaning than dogs that only wear one for occasional walks.
