How to Get Dog Urine Out of Carpet, and the Smell
Blot, rinse cool, then enzymes. The two things that make it permanent are a steam cleaner and an ammonia cleaner, and both are what people reach for first.

How to get dog pee out of carpet in 4 steps
| Step | Do this | Why |
|---|---|---|
| 1. Absorb | Thick paper towels over and, if you can, under the spot; press for several minutes | Pressure lifts more than wiping |
| 2. Rinse | Clean, cool water into the spot | Dilutes what the paper could not lift |
| 3. Blot dry | Towels or a wet vacuum, no rubbing | Rubbing spreads it through the pile |
| 4. Neutralise | An enzyme cleaner, left to sit | Breaks down the compounds that smell |
Blotting rather than wiping is the part people get wrong under pressure. Wiping and rubbing push urine deeper and wider, and a stain that reaches the backing is a different job from one that sits in the pile.
Enzymes do the part water cannot
Water dilutes urine. It does not remove the compounds that keep announcing the spot to a dog weeks later, which is why an odour that seems gone comes back on a humid day. An enzyme cleaner is the step that finishes the job.
Enzyme cleaners break those compounds down instead of covering them. Humane World’s guidance is to follow the clean with a pet odour neutraliser, and to give it time rather than blotting it straight back up.

Rocco & Roxie Enzyme Stain & Odor Eliminator, 32 fl oz
128,422 ratings at 4.4, with owners reporting it works on old stains as well as fresh ones.

| Type | Enzyme cleaner |
|---|---|
| Size | 32 fl oz |
| Owners praise | Old and new stains |
| Mixed reports | Scent strength, value |
Suits the owner with a spot the dog keeps going back to. Owners report it clearing both fresh accidents and stains that were already set, which is the harder case.
The scent divides opinion, some finding it pleasant and others too strong, and so does value. Soak the spot rather than misting it: an enzyme has to reach as far as the urine did, including the backing.
Buy it if
- You have a spot the dog keeps returning to
Don't buy it if
- A strong scent in the room bothers you
Two things that make it permanent
Heat. Humane World is explicit that steam cleaners should not be used on urine, because the heat permanently sets the stain and the odour by bonding the protein into man-made fibres. That also rules out hot water in a portable extractor on a urine spot, however tempting the heated setting is.
Ammonia, and vinegar. Urine contains ammonia, so an ammonia cleaner smells to a dog like another dog. Humane World advises avoiding both ammonia and vinegar, because a strong chemical odour can encourage the animal to re-mark the same place.
When the spot has gone through to the backing
A long-standing patch that smells after cleaning has usually soaked past the pile. An extractor such as the Bissell Little Green pulls liquid back out of the underlay in a way towels cannot. Bissell Little Green or Hoover CleanSlate compares the portable machines for exactly that job.
Run it with cool water, extract, then enzyme-treat and leave it. If the smell survives that, the pad beneath may need replacing, which is a flooring job rather than a cleaning one.
BISSELL Little Green Portable Carpet Cleaner, 1400B
94,744 ratings at 4.5, a portable extractor owners name for pet accidents and small cleanups.
Current price shown on Amazon. We may earn a commission.
| Type | Portable carpet and upholstery cleaner |
|---|---|
| Owners praise | Pet stains, small cleanups |
| Mixed reports | Build quality |
Suits the owner facing an old patch rather than a fresh puddle. Owners name pet stains and small cleanups as its job, one describing puppy spots on white carpet, and most call it worth the money against a professional visit.
Build quality is where reports divide. On a urine spot, fill the tank with cool water only.

Repeat accidents are a training or health question
A dog returning to 1 patch is following a scent the cleaning missed, and a second enzyme soak usually settles it. A dog suddenly having accidents in several places is a different matter, and a change in frequency is worth a vet’s opinion rather than a stronger cleaner.
For the behaviour side, the settling-in problems that cause indoor accidents are covered in why a dog fears fireworks, and for a puppy arriving at Christmas, what a dog coat has to do is the other purchase worth getting right.
