Quick answer

Your couch smells like dog because body oils, saliva, dander and sometimes urine soak into the fabric and the foam beneath it. Vacuum it, then let baking soda sit on the fabric to lift surface odor. If the smell is strong or smells like pee, an upholstery enzyme cleaner is what breaks it down, because baking soda alone cannot.

Free fix vs. permanent fix

Free fix · 1 hour plus drying

Vacuum, baking soda, wash what comes off

  • Vacuum the seams and cushions with the upholstery tool
  • Sprinkle baking soda on the fabric and leave 30 minutes or more
  • Vacuum it up slowly and thoroughly
  • Wash throws and removable covers per the care label

How long it lasts: Works for surface dog smell. It does little for urine or odor deep in the cushion, which comes back on warm or humid days.

An upholstery enzyme odor eliminator

Pet odor, and urine especially, comes from compounds that soap and baking soda do not break down. Enzymes digest those compounds, so the smell goes instead of being covered up. This is what to use when the free steps leave the couch smelling the same on a warm day.

What to get: Upholstery enzyme odor eliminator

How long it lasts: Gets rid of the smell at its source, as long as it reaches what is causing it and the couch dries fully.

Why it happens

1

Skin oil, saliva and dander

Dogs shed oil and dander every time they sit or sleep on the couch. Fabric absorbs it, and the smell builds up slowly until you stop noticing it, though guests do.

2

Urine

Accidents, marking or a puppy can leave urine that soaks through the fabric into the foam. It dries to crystals that smell strongly again when it gets damp or humid.

3

Moisture trapped in the cushions

A wet dog, a spill or a cleaning job that soaked the couch can leave damp foam. Damp foam grows musty smells that mix with the dog odor.

4

Odor that stays in unwashed covers and throws

Pet beds, throws and cushion covers that never get washed hold odor, and then add it back to the couch.

Do these in order, starting with the simplest.

  1. Read the care tag

    Look under a cushion for a code. W means water-based cleaners are fine, S means solvent only, WS allows either, and X means vacuum only. If it says S or X, skip water-based steps.

  2. Vacuum everything

    Tool used: Vacuum with upholstery tool

    Take off the cushions and vacuum the seams, the cushion sides and the frame. Dog hair and dander hold the smell.

  3. Cover the fabric with baking soda

    Tool used: Baking soda

    Sprinkle a thin, even layer and leave it for at least 30 minutes, or overnight if the room allows. Vacuum it all up slowly.

  4. Wash what can be washed

    Wash throws, removable covers and pet blankets using the label settings. Dry them fully before putting them back.

  5. Treat urine spots with enzymes, lightly

    Tool used: Upholstery enzyme odor eliminator

    Blot fresh pee with a clean white cloth and never rub. Mist the spot with enzyme cleaner until it is just damp, not soaked, leave it for the time on the label and blot again. Air-dry with a fan, and test on a hidden area first.

When free fixes aren't enough

If the couch still smells after the baking soda, or it smells strongly like pee on warm days, the odor is in the foam where powder cannot reach. Enzyme cleaner is made for that and will do more than another round of baking soda. If the smell comes from a large soaked area, the foam may be ruined, and the cushion insert may need replacing. Do not soak the couch. Too much water is how a dog smell becomes a damp, musty smell.

How to get rid of dog smell on couch cushions for good

Treat the fabric and the cause together. Clean the couch once, then keep the oils from reaching it again.

  • Cover the favorite spot with a washable throw or cover.
  • Wash the dog's bed and blankets, since they carry the same odor.
  • Brush the dog often, and bathe it as its coat needs.
  • Open a window when you clean and let the cushions air out.
  • Rotate the cushions so no one spot stays damp or flat.

What to skip

Air fresheners, steam and heavy soaking

Sprays and plug-ins cover the smell without removing it. Steam heat can set urine into the fibers, and soaking wets the foam so it stays damp. Light, targeted treatment works better than heavy treatment.

Frequently asked questions

Couch smells like dog pee: how do I know if it is urine?
Check with a UV blacklight in a dark room. Old urine often glows yellow-green, though some other stains glow too. Treat only those spots. Blot fresh accidents first, and never rub.
Why does my couch smell like pee?
Urine is the likeliest cause if you have pets or a toddler. Moisture trapped in the cushion or mildew can also smell sharp. Use a blacklight to find urine, and look for damp patches if you do not find any.
How to stop couch smelling like dog?
Put a washable throw on the couch and wash it weekly, vacuum the seams, brush and bathe the dog, and air out the cushions in the sun. Keep wet dogs off it until they are dry.
How to get rid of dog smell on couch quickly?
Vacuum, cover with baking soda for 30 minutes, then vacuum again. Wash the throws. For a stronger smell, use an enzyme cleaner on the fabric and let it air dry with a fan.
