How to Get Rid of Dog Smell in the House
Dog smell lives in soft, absorbent things — the bed, the blankets, the sofa cover, the rug — and almost never in the air. So the fix is a laundry sequence, not a spray. Strip the three or four items your dog lies on most, take the hair off them while they're dry, and wash them properly. You'll usually notice the difference the same evening.
Air fresheners do nothing to the source. They add a second smell to the first one.
Why a house that has a dog in it smells
The odour isn't really coming from your dog — it's coming from what lives on your dog. AKC's explanation of the wet-dog effect covers the whole mechanism: yeasts and bacteria live on a dog's skin and produce "micro excreta" in the form of volatile organic compounds, and when the coat gets wet, evaporation carries those compounds into the air. The result, per the chemist AKC quotes, is "a mixture of scents, including almond, fruit, honey, and mushroom, with hints of sulfur and feces." Their conclusion is worth keeping in mind: "it's not the dogs themselves we should be blaming for the smelling terrible, but rather the microorganisms they carry."
Those compounds, plus skin oil and saliva residue, transfer onto every soft surface your dog contacts and accumulate there. Fabric is the reservoir. That's why the smell is strongest at nose height over the dog bed and weakest in the middle of the room.
The order of operations
Do these in order. The order matters because the first step changes how well the second one works.
| Step | What | Why this order |
|---|---|---|
| 1 | Open windows, get air moving | Clears the airborne share while you work |
| 2 | Take the hair off bedding and covers while dry | Water clumps hair and welds it in |
| 3 | Wash bedding, blankets, covers — separate load, hot if the label allows | This is the actual source removal |
| 4 | Vacuum carpet, rug, sofa crevices and floor edges | Removes the dander and debris fabric can't hold |
| 5 | Wipe hard floors and skirting | Oil residue transfers here too |
| 6 | Run an empty deodorising cycle in the washer | Stops the machine re-scenting the next load |
| 7 | Reassess the dog, not the house | If the smell is on the dog, steps 1–6 won't hold |
Source: bedding and laundry sequence per AKC, "How to Clean Your Dog's Bed and Why It's Important"; odour mechanism per AKC, "Why Do Wet Dogs Smell So Bad?"
Steps 2 and 3 remove more odour than everything else combined, and step 2 takes about two minutes.
Step 2, in detail — because this is the one people skip
AKC's bed-cleaning guidance puts de-hairing before washing for a concrete reason: mixing dog hair with water causes clumping. Their instruction is to vacuum the surface, crevices and sides of the bed first, then "use a lint roller or masking tape, or wear rubber or latex gloves, and wipe the bed to lift the remaining hair."
A damp rubber dish glove does this fine. So does a reusable static glove — Oxford-fabric palm, five-finger, 5.1 x 6.7 inches (13 x 17 cm), rinse under the tap and air-dry between uses. Wipe in one direction so the fur gathers into a strip at the centre of the palm and peels off in a piece, rather than back and forth, which pushes half of it back into the weave.
Skip this and you get a bed that comes out of the machine clean-smelling but visibly furrier, with matted fur worked into the fabric that now needs picking out by hand.
Step 3, in detail — wash it like it matters
Three specifics from AKC's guidance:
Frequency. Wash bedding weekly to reduce the risk of spreading parasites or zoonoses. If you're currently smelling the house from the doorway, weekly is where you're heading, not where you start.
Temperature. High-temperature programs can kill germs and parasites and provide a deep clean — so use the hottest cycle the label tolerates. Then air-dry the bed rather than tumbling it, which prevents clumping and mould growth in thick filling.
Detergent. Use a fragrance-free, pet-friendly detergent. Heavily perfumed detergent is the same mistake as an air freshener, one step further upstream: it puts a second scent onto the thing your dog sleeps on for eight hours a night.
That's the brief our pet laundry detergent sheets are built to: fragrance-free, dye-free, no chlorine bleach and no optical brighteners, with an enzyme formula — a protease — aimed at the urine, drool and body-oil residue that is the actual odour source, breaking those soils down rather than covering them. Static-reducing additives help whatever hair you missed release into the lint filter instead of resettling. Drop the flat sheet into the drum rather than the dispenser tray; it dissolves in cold or warm water and works in front-load and top-load machines alike. One sheet for a normal load, two for a large or strongly-smelling one — 30 sheets covers up to 60 loads.
The rest of what we make for this part of the routine is in pet care.
For a washer that has itself started to smell, AKC suggests running an empty cycle afterwards to clear lingering odours, with white vinegar and a half cup of bicarbonate of soda in the dispenser.
When the smell isn't the house
If you've washed everything and the smell is back in two days, the source is the dog, and at that point it's a veterinary question rather than a cleaning one.
AKC identifies secondary yeast or bacterial infections as the most common medical reasons a dog smells — specifically overgrowth of Malassezia yeast and Staphylococcus pseudintermedius bacteria on the skin — and notes that "Dog allergies often begin the process, which leads to scratching and licking, behaviors that can open the door for infections."
Their list of signs to take to a vet: itchy behaviours like head shaking or licking, changes in skin colour ranging from red to black, hair loss, crusting, red ears, or an odour that worsens over time.
No amount of laundry fixes any of that, and a grooming tool certainly doesn't. If you're seeing those signs, book the appointment and treat the housework as the second job.
Frequently Asked Questions
Q: What about baking soda on the carpet?
A: It's a reasonable adjunct for a rug that can't be washed — sprinkle, leave it an hour or two, vacuum thoroughly. It absorbs rather than masks, which puts it on the right side of the line. It won't outperform actually washing the things that can be washed.
Q: Do air purifiers help with dog smell?
A: They help with airborne particles and some odour compounds while running, which can make a room feel better. They don't touch the reservoir in the fabric, so the smell returns whenever the purifier is off. Useful as a supplement, not as the plan.
Q: How often do I need to bathe my dog for this?
A: Less often than you'd think, and over-bathing can dry the skin. Washing your dog's bedding and blankets on a weekly rhythm does more for household odour than an extra bath does — and if your dog genuinely smells bad between normal baths, that's the vet-visit list above rather than a bathing-frequency problem.
Q: My dog's collar and harness smell. Do those count?
A: Yes — anything absorbent that sits against the skin for hours holds the same residue. Webbing collars and fabric harnesses can usually go in a mesh bag on the same load as the bedding, as long as the hardware is safe to wash.
