The short answer
What Causes the Smell
The odor comes from moisture trapped in porous materials like carpets, drywall, insulation, or wood. When these stay damp, bacteria and mildew multiply, releasing a musty, sour scent. A leak behind a wall, a damp basement, or a wet roof can all create this problem.
Even a small spill that soaks into a floor can turn into a wet dog smell if it is not dried fully. High indoor humidity can also make existing moisture worse. The first step is to find where the water is coming from and stop it.
- Check under sinks and around toilets for slow leaks
- Inspect the roof and attic for water stains
- Feel walls and floors for damp spots
- Look at the water heater for rust or moisture
- Notice if the smell is stronger in one room
Find the Water Source
Start by looking for visible leaks. Check pipes, the washing machine hookup, and the water heater. A plumber can help if you cannot find the source. Leak detection tools, like moisture meters, can locate hidden water behind walls or under floors.
If the smell is in a crawl space or under the house, water may be pooling there. A slow leak from a pipe can soak into the subfloor over weeks. Finding the source early prevents more damage and reduces the odor.
- Use a flashlight to inspect dark corners
- Feel for dampness on drywall and baseboards
- Listen for dripping sounds in walls
- Monitor the water meter for unusual usage
- Check the exterior for poor drainage near the foundation
Dry the Affected Area
Once the leak is stopped, dry the area as much as you can. Open windows and use fans to move air. Dehumidifiers help pull moisture from the air, especially in closed spaces. If the weather is dry, let fresh air circulate through the house.
For wet carpets or upholstery, use a wet vacuum to extract water. Remove any soaked items that cannot be dried quickly. The goal is to get the material dry within a day or two to stop mold from growing. Structural drying may be needed for larger areas.
Remove Odor Sources
Some materials cannot be saved. Wet insulation, carpet padding, or drywall often need to be cut out and replaced. Trying to dry them can leave a lingering smell. Remove anything that is heavily contaminated.
For hard surfaces, clean with a mild detergent and water. Avoid harsh chemicals that can mask the smell without removing the cause. If the odor persists, the material may need professional attention. The pros can remove wet insulation and replace damaged drywall.
When to Call the Pros
If you cannot find the source or the smell covers a large area, it is time for help. Water damage pros use moisture mapping and leak detection to find hidden water. They also have industrial drying equipment to dry out walls and floors thoroughly.
If the smell does not fade after drying and cleaning, the pros can locate hidden moisture and remove water-soaked materials. They use moisture meters and industrial drying equipment to handle larger areas. Acting quickly helps prevent the odor from spreading further.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Can I get rid of the wet dog smell myself?
You can try cleaning and drying the area, but if the source is hidden or the material is soaked, the smell may return. Removing wet carpet or insulation is often necessary. If the odor persists, professional drying or removal is the next step.
Is a wet dog smell a sign of mold?
It can be. Mold and mildew thrive in damp conditions, and their presence often produces a musty odor. If you see visible mold or experience allergy symptoms, consider a mold professional. They can assess the situation and recommend safe removal.
Will the smell go away once the area dries?
Sometimes, but not always. If water soaked into porous materials like drywall or insulation, the smell can linger even after drying. The odor may return during humid days. Removing the affected material is the most reliable way to get rid of it.
