Which layer is sealed
| Product | Sealed layer, as stated | What you wash | Best use |
|---|
| PetFusion Ultimate | 100% waterproof liner around the foam | Removable cover, machine washable | A big dog that has occasional accidents |
| NONONFISH calming bed | Waterproof, anti-slip base | The whole bed, washer and dryer | Dogs up to about 10 lb |
| Mabozoo crate pad | Waterproof PU core, 5 layers, chew-resistant both faces | Whole pad, machine washable | A crate, and a chewer |
| Tranqun mats (4) | Waterproof membrane between fleece and coral velvet | All four, normal wash load | The daily top layer |
| Coolaroo elevated | No fill to seal — moisture-resistant HDPE mesh | Hose it off | Outdoors, utility rooms, a wet dog |
Note what the washing column tells you. A bed whose cover alone is washable needs stripping, laundering and re-dressing after every accident, and in the meantime the dog has no bed. A set of four small mats means there is always a clean one. That difference is the whole argument for the two-layer setup below.
The two-layer setup, which is what actually works
For a dog having accidents regularly, do not try to solve it with one bed. Buy a bed with a sealed liner and put a cheap washable waterproof mat on top of it, then swap the mat daily and the cover weekly.
- Bottom: the bed that protects the foam. PetFusion for a large dog, the NONONFISH for a small one, a crate pad if the dog sleeps in a crate.
- Top: four waterproof mats or two large washable pads. These cost very little, go in a normal wash, and mean the dog is never sleeping on a stripped bed while something dries.
- Spare: if the dog is incontinent nightly rather than occasionally, own two bottom layers. A bed that is damp in its seams smells within a week, whatever the liner does.
The economics work out in favour of this too: a second cheap top layer costs a fraction of a second orthopedic bed, and the orthopedic bed is the part you are protecting.
Why foam is the thing you are protecting
Urine in foam is the end of a bed. It is not a smell problem you can wash out — the liquid moves into the cells and stays, and shredded-foam fill is worse than a solid slab because the pieces hold it individually and never dry evenly. This is why the PetFusion’s spec sheet is more relevant to this page than its comfort: a single 3.5 in solid CertiPUR-US slab inside a stated 100% waterproof liner is a repairable system, and a sack of damp chips is not.
It is also why the AKC’s bed guidance treats washability as a core criterion alongside size and support, rather than a nice-to-have. If you are choosing between two beds and one has a removable, machine-washable cover and the other does not, the choice is made — and our dog bed buying guide covers the rest of those criteria.
Hygiene, briefly, because this is the one page where it matters
Soiled bedding is not just a laundry question. The CDC’s guidance on dogs and human health is about the germs and parasites carried in dog feces, and the practical implications here are simple: wash soiled bedding hot and dry it fully, wash your hands afterwards, and keep bedding that has been soiled with feces away from the rest of the household laundry. Dry it completely — a waterproof membrane that is still damp in the middle is the one place a smell will reliably establish itself.
If the incontinence is new, start with the vet
Worth saying plainly on a page that sells bedding. A previously clean dog that starts leaking is telling you something, and no bed answers it. Sudden incontinence, a dog drinking far more than usual, straining, or a change that arrives over days rather than years is a veterinary conversation first. Buy the bedding to manage the mess while you get an answer, not instead of getting one.
For an old dog whose problem is mobility rather than continence — it cannot get up quickly enough — the bed matters in a different way: support and a low, easy entry. The senior dog bed picks cover that, and a ramp or steps may be the purchase that matters more.
Puppies are a different buy
Do not buy a good waterproof bed for a puppy. The AKC’s own new-puppy list has a bed and a crate on it, but the bed a 10-week-old puppy needs is a cheap washable one it can grow out of, chew at, and have accidents on. Four waterproof mats and a crate pad will see out house-training for the price of a takeaway, and then you buy the real bed. The puppy bed picks and the puppy crates are sized for that stage.
What we would actually buy
For a medium or large dog that has accidents, the PetFusion Ultimate with four Tranqun mats on top. The bed survives because its liner is stated 100% waterproof and its foam is solid rather than shredded; the mats mean you strip a 24 by 16 inch square in the morning instead of wrestling a cover off a bed. That combination is cheaper than most single “waterproof” orthopedic beds.
For a small dog, the NONONFISH: the whole bed goes in the washer and the dryer, the base is waterproof and non-slip, and it suits dogs up to about 10 lb. The cover is not removable, so you wash the entire thing — which is only a drawback if you own one, so own two.
For a crated dog, the Mabozoo pad, because it solves both crate problems at once: a waterproof PU core so an accident stops at the pad, and chew-resistant faces on both sides so it can be flipped. It is quilted rather than cushioned, so an arthritic dog wants something under it.
And for the dog whose problem is water rather than urine — the one that swims, or lives in a utility room, or comes in soaked every day — the Coolaroo. A taut HDPE mesh on a frame has no fill to soak, no cover to strip and no seam to hold a smell. You hose it. It is firm and unpadded, which rules it out for a stiff old dog and makes it close to perfect for a wet young one.
