Washable Dog Nappy Pads: How Absorbent Are They and How Do They Work?

Are washable dog nappy pads really absorbent? Can they help with incontinence, and how do you know which size is right for your dog?
These are important questions, especially when caring for a dog who experiences urinary leakage or accidents indoors.
At Glenndarcy, our washable dog nappy pads were developed to provide a practical, reusable option for our dog nappies, Flexi-Pants and compatible belly bands.
We also believe customers deserve clear information about how our products work and what they can realistically expect.
That’s why we’ve carried out our own practical absorbency tests using measured amounts of water.
In this guide, we’ll explain the fabric construction, share our testing observations and help you decide whether washable pads might suit your dog.
What Are Washable Dog Nappy Pads?
Washable dog nappy pads are reusable absorbent inserts designed to sit inside compatible dog nappies or belly bands.
Unlike the waterproof outer garment, which helps prevent moisture reaching furniture and surrounding surfaces, the pad is designed to absorb and retain liquid.
Our Glenndarcy washable pads attach to compatible products using plastic poppers, helping to keep them positioned correctly.
They’re available in sizes A to E, with different sizes designed to suit different garments and coverage requirements.
How Do Glenndarcy Washable Pads Work?
Our waterproof-backed pads contain several fabric layers, each serving a different purpose.
The Top Layer: Helping Moisture Move Inwards
The upper layer is synthetic suede, designed to encourage moisture to move through to the absorbent material beneath.
You may notice that water initially sits on or moves across the surface before being absorbed. This is something we observed during our own testing.
The Absorbent Middle Layers
Beneath the surface are multiple layers of absorbent bamboo-cotton fabric.
These layers help absorb and retain moisture.
Sizes A, B, C and D contain four absorbent middle layers, while size E has three.
The Waterproof Backing
The bottom layer incorporates waterproof protection, designed to help stop moisture passing through the underside of the pad.
This provides an additional protective barrier when used inside a compatible Glenndarcy product.
It’s important to remember that waterproof and absorbent are not the same thing. The absorbent layers take in liquid, while the waterproof backing helps prevent it passing through.
How Absorbent Are Glenndarcy Washable Dog Pads?

Rather than simply describing our pads as absorbent, we decided to carry out some practical tests ourselves.
We applied measured amounts of water to different pad sizes and observed how the material behaved.
Our Washable Pad Water Tests
|

Water used |
Observation after one hour |
|
A |
50 ml |
Absorbed without penetration through the backing |

B |
50 ml |
Absorbed without penetration through the backing |
|
C&D |
225 ml |
Absorbed without penetration through the backing |
|
E |
225 ml |
Absorbed without penetration through the backing |
These are our own practical testing observations, not certified laboratory absorbency ratings.
The volumes above represent the amounts tested, not the maximum quantities the pads can necessarily hold.
We have not established a maximum absorbency capacity for each size, and our findings should not be interpreted as a guarantee against leaks during everyday use.
What Did We Notice During Testing?
One interesting observation was that water did not always absorb immediately when first applied.
Instead, some liquid initially moved across the top surface before gradually soaking into the fabric.
This may relate to the surface characteristics of the material or manufacturing finishes.
It is possible that laundering affects how the surface wets, although we haven’t established that through controlled testing.
Once absorbed, the measured water did not penetrate the waterproof backing in the tests described above after one hour.
Does This Mean a Pad Can Hold 225 ml of Dog Urine?
Not necessarily.
Our testing showed that the particular C, D and E pads tested absorbed 225 ml of water without liquid passing through the backing.
However, real-life conditions are different.
A dog’s movements, body position, the speed at which urine is released, pressure on the pad and the fit of the garment can all affect performance.
Urine also differs from plain water.
A pad that performs well in a stationary water test may behave differently when worn by an active dog.
Our tests demonstrate what we observed under those conditions, not a guaranteed capacity or duration of protection.
Can Washable Dog Pads Be Used Overnight?
That depends on your dog’s individual needs.
Some dogs experience occasional drips or smaller amounts of leakage, while others may release much larger volumes of urine.
For lighter leakage, a washable pad may be a convenient option.
For heavier incontinence, particularly overnight, we generally recommend considering a suitable high-absorbency disposable incontinence pad.
Whatever type of pad you choose, it should be checked and changed regularly.
Leaving a dog in a wet nappy for prolonged periods can cause discomfort and skin irritation.
Why Does My Dog’s Nappy Sometimes Leak?
Leaks don’t necessarily mean the pad or waterproof fabric is faulty.
Several things can contribute:
- The pad may not provide enough absorbency for the amount of urine produced.
- The garment may be too loose or incorrectly positioned.
- The pad may not cover the area where urine is released.
- Urine may escape around the sides before it can be absorbed.
- Pressure or movement may cause absorbed moisture to escape.
Correct sizing, positioning and an appropriate absorbent insert are all important.

How Do I Choose the Right Washable Pad Size?
Glenndarcy washable pads come in sizes A, B, C, D and E.
The correct size depends on the particular Glenndarcy garment you’re using, rather than simply your dog’s breed or weight.
Always consult our washable pad sizing chart or the information in the relevant nappy or belly band listing.
Choosing a larger pad doesn’t automatically mean it will work better.
A pad that is too large may bunch up, interfere with the fit or fail to sit correctly inside the garment.
How Do I Wash Glenndarcy Reusable Dog Pads?
Our washable pads are designed to be cleaned and reused.
For regular care:
- Machine wash at 30°C.
- Use a non-biological detergent.
- Avoid fabric softener.
- Tumble dry on a low setting if required.
- Do not iron.
Check pads regularly for wear or deterioration, particularly if they’re used frequently.
Having spare pads available makes it easier to change them promptly while others are being washed.
Are Washable Dog Pads Better Than Disposable Pads?
Both have advantages.
Washable pads can be a practical reusable alternative, particularly when your dog’s leakage levels are manageable and you’re able to change and wash the pads regularly.
Disposable incontinence pads may offer a more suitable solution for dogs producing larger quantities of urine or requiring additional overnight protection.
Many owners find that using both types, depending on the situation, offers greater flexibility.
The most important consideration is your dog’s comfort and the level of absorbency required.
Frequently Asked Questions About Washable Dog Nappy Pads
Are washable dog nappy pads waterproof?
Glenndarcy waterproof-backed washable pads have absorbent fabric layers and a waterproof protective underside. However, liquid can still escape around the edges if the pad is overloaded or incorrectly positioned.
Can I use washable pads in male dog belly bands?
Yes, Glenndarcy washable pads can be used with compatible male belly bands. Check the relevant product listing to establish which pad size and fastening arrangement you need.
How often should I change my dog’s washable pad?
There is no single interval suitable for every dog. Check the pad frequently and change it promptly when wet or soiled.
Can I use disposable pads instead?
Yes. Many Glenndarcy garments can accommodate suitable disposable absorbent pads. Choose the correct shape and size to avoid bunching or gaps in coverage.
Why does water sometimes roll across a washable pad before soaking in?
We observed this during our own testing. Surface wetting characteristics and fabric finishes may contribute, but we have not confirmed the precise cause.
