Quick answer

How to get rid of dog smell in house comes down to three steps: find where the smell lives, wash or clean those things, then treat what you cannot wash. Dog bedding, the dog's coat, carpet and the couch hold most of it. An enzymatic pet odor eliminator breaks down the residue in carpet and fabric, where perfumed sprays only cover it for a few hours.

Free fix vs. permanent fix

Free fix · 1-2 hours

Wash, vacuum and air out

  • Wash dog beds, covers and blankets in hot water
  • Vacuum floors, couch cushions and under furniture
  • Open windows for 30 minutes and run a fan
  • Bathe the dog, or wipe the coat with a damp cloth

How long it lasts: The smell fades for days to a few weeks. Odor in carpet, couch cushions and the dog's coat comes back until the source is treated.

An enzymatic pet odor eliminator spray

Dog odor comes from skin oil, saliva and dander soaked into fabric and carpet. A washer reaches only what fits inside it. Enzyme sprays use enzymes that break down that organic residue, so the odor goes away instead of being covered with perfume.

What to get: Enzymatic pet odor eliminator spray

How long it lasts: Weeks to months. It lasts as long as it takes the dog to put new residue back on the spot.

Why it happens

1

The dog bed and blankets

Fabric the dog lies on every day soaks up skin oil, saliva and dander. Most of the smell lives here.

2

The dog itself

Oily coats, wet fur, dirty ears, bad teeth and full anal glands all smell. If the odor follows the dog from room to room, treat the dog.

3

Carpet, rugs and the couch

Fibers hold odor, and a vacuum alone does not lift it. The spots where the dog sleeps or sits smell strongest.

4

Damp air and poor airflow

Wet fur after walks, humid rooms and closed windows trap odor. A dirty furnace filter keeps recirculating it.

5

Accidents you missed

An old urine spot under a rug or on a baseboard keeps giving off smell for months, even when the room looks clean.

Try this first (free)

Do these in order, starting with the simplest.

  1. Wash the bedding in hot water

    Tool used: Washing machine

    Wash dog beds, covers, throws and any blanket the dog sleeps on. Use the hottest water the label allows and add a cup of white vinegar to the rinse. Dry them fully, since damp fabric smells worse.

  2. Vacuum everything the dog touches

    Tool used: Vacuum cleaner

    Go over carpets, rugs, couch cushions and under the furniture. Empty the canister or bag outside afterward.

  3. Sprinkle baking soda on dry carpet

    Tool used: Baking soda

    Cover the carpet and rugs lightly, leave it for a few hours or overnight, then vacuum it up. It takes the edge off mild odor.

  4. Open windows and change the furnace filter

    Cross-ventilate for 30 minutes. If you have forced-air heat or cooling, change the filter. In a home with dogs, that is often every one to three months.

  5. Clean the dog

    Bathe your dog with dog shampoo about every four to eight weeks unless your vet says otherwise, and dry the coat fully. Brush often, and wipe paws and fur with a damp towel after wet walks.

  6. Spray what you cannot wash

    Tool used: Enzymatic pet odor eliminator spray

    Test a hidden spot first. Then spray carpet, the couch and the dog's favorite spot until damp, not soaked. Let it air dry, and follow the label for how long it needs.

When free fixes aren't enough

If the room still smells after you wash the bedding and vacuum, the odor is in fibers the washer and vacuum cannot reach: carpet, rugs, couch cushions and the mattress. An enzyme spray goes into those fibers and breaks down the residue. If it still smells after you treat everything, look for old urine spots, damp or mold, which smells musty rather than doggy. A medical cause in the dog, such as ears, skin or teeth, is worth a vet visit.

How to get rid of dog smell in house fast: the 30-minute reset

  1. Open two windows and run a fan to push air out.
  2. Strip the dog bed, throws and couch covers into the washer.
  3. Vacuum the couch and the main walkways.
  4. Wipe the dog's coat and paws with a damp towel.
  5. Spray the dog's favorite spot with enzyme cleaner and let it dry.

This takes the edge off before guests arrive. It does not replace the deeper wash.

How to get rid of dog smell in room when your bedroom smells like dog

If your bedroom smells like dog, the dog is probably sleeping on your bed. Wash the sheets, blanket and mattress protector weekly, and vacuum the mattress. Give the dog a washable bed on the floor and spray that spot with enzyme cleaner. Air out the room each morning. A closed room with a dog bed in it traps odor fast.

How to get rid of dog smell in rental house without losing your deposit

Do the washing, vacuuming and enzyme spray as above. Check your lease, since many ask for professional carpet cleaning at move-out. Wash curtains, wipe baseboards, replace the furnace filter and ventilate for a few days. Keep receipts and take photos of the carpet when you finish. Use a washable rug on top of carpet from now on.

What to skip

Perfumed sprays, candles and plug-ins

They cover odor for a few hours and mix with it. Skip them until the source is clean. Skip essential oil diffusers around dogs too, since some oils, including tea tree, are harmful to dogs and cats.

Frequently asked questions

House smells like dog even though I clean: how to fix house smelling like dog?
Mopping floors does not reach the dog bed, couch cushions, carpet backing or the dog's coat. Smell each one to find the source. Wash what washes, vacuum, then treat carpet and furniture with an enzyme spray.
How to stop house smelling like dog after you wash everything?
Keep it up with small habits. Wash the dog's bedding weekly, brush and bathe the dog on a schedule, wipe paws after wet walks, use a washable throw on the couch and change the furnace filter on time.
How to stop house from smelling like dog when you have more than one?
Give each dog one washable bed in a set spot, wash all of them weekly, and spray those spots with an enzyme cleaner every few weeks. Dry wet dogs at the door, not on the couch.
How to stop house smelling of dog if the smell is mostly on the dog?
Bathe the dog with dog shampoo about every four to eight weeks, brush often and keep ears and teeth clean. If the dog still smells right after a bath, ask your vet to check the ears, teeth, skin and anal glands.
Do air fresheners and candles get rid of dog smell?
No. They mask it for a few hours. The smell returns because the oils and dander are still in the fabric. Clean the source first, then use an enzyme spray if you need more.
