Most of us love our dogs, but cleaning urine stains is definitely one of the least enjoyable tasks that come with pet ownership. While you may become used to the odor over time, guests usually notice it immediately.
Even small accidents can leave long-lasting smells and, if ignored, may reduce the value of your home. This is why, when having pets, deep cleaning your home is essential for keeping your carpets and indoor air fresh.
Why does dog urine smell return even after cleaning? Dog urine smells often return because uric acid crystals remain in the carpet and release odor when rehydrated by humidity. Cleaning the surface alone is not enough, so using vinegar, baking soda, or enzyme cleaners is essential to break down these crystals completely.
To help you tackle the problem quickly and effectively, in this article I will show you how to remove dog urine smells from carpets using simple, proven methods that restore freshness and prevent lingering odors.

What To Do If the Urine Stain Has Dried
Once dog urine dries, it binds tightly into carpet fibers. The goal is to rehydrate the stain, break it down, and extract as much residue as possible. The odor may intensify temporarily, but this is part of the removal process.
You Will Need
- White vinegar
- Spray bottle
- Baking soda
- Clean white cloth
- Optional, paper towels or newspaper
Step 1: Apply White Vinegar Using a Spray Bottle
Fill a spray bottle with white vinegar and mist the affected area until it is damp. Spraying helps the vinegar penetrate evenly into the carpet. This allows it to reach the dried urine crystals and loosen them while killing bacteria.
Let it sit for 15 to 20 minutes.
Note: The odor may increase during this step, but this is expected because the vinegar is reactivating the dried urine so that it can be removed.
Step 2: Blot with a White Cloth
Once the vinegar has soaked in, place a white cloth over the area and press down firmly. Do not rub, because rubbing can push the urine deeper into the carpet or spread it to uninfected areas of the carpet.
Rotate to dry sections of the cloth until no more liquid comes up.
You can use paper towels, newspaper, or a sponge to absorb the remaining moisture. Removing as much liquid as possible helps the next step work more effectively.
Note: Avoid using a colored cloth, because dyes may transfer onto the carpet.
Step 3: Apply Baking Soda to Dry and Neutralize Odor
Sprinkle a generous, even layer of baking soda over the damp area.
Gently work the baking soda into the carpet with your white cloth so that it reaches any remaining moisture.
As it absorbs the vinegar and urine mixture, the baking soda will begin forming a light crust. This reaction helps neutralize odors at the source.
Step 4: Vacuum the Carpet
Once the baking soda is dry, vacuum it thoroughly. During this step, it’s possible for some of the odor to transfer into the machine, so knowing how to get rid of dog smell from vacuum cleaner can help prevent the scent from circulating back into your home.
If the carpet can be moved, take it outside and beat it from the back to remove deeper residue, then vacuum it again. If you are short on time, a stiff brush can help lift the dried baking soda before vacuuming.
Additional Data: Why Pet Urine Smells Linger
Cause |
Explanation |
|---|---|
Urea Breakdown |
When urine dries, urea turns into ammonia, which produces a sharp smell. |
Bacteria Growth |
Moisture and warmth allow bacteria to multiply, increasing odor intensity. |
Uric Acid Crystals |
These crystals bond with carpet fibers and release odors whenever they are rehydrated, such as on humid days. |
Padding Absorption |
Carpets with thick padding trap urine deeper, making surface cleaning less effective. |
Final Thoughts
Pet odors can be overwhelming and may discourage visitors or potential homebuyers if the smell is noticeable. Handling accidents quickly keeps the odor from becoming permanent. Cleaning your carpets regularly and maintaining your vacuum cleaner helps you keep your home fresh, hygienic, and welcoming. If the odor has seeped deep into the carpet padding or keeps returning, some homeowners consider professional help, and understanding house cleaning costs can make it easier to decide whether hiring a service is the right move.
With the right methods and consistent care, you can effectively remove stains and odors, even from dried urine, and enjoy a clean home alongside your pets.
When it comes to dog urine on the carpet, I treat it like I would a stubborn oil stain on a crisp white shirt. Soaking the area with a mixture of vinegar and water as soon as possible always works in lifting the stain. For the smell, I swear by a sprinkle of baking soda left overnight and vacuumed up the next day – your house won’t be reminding anyone of an unattended fire hydrant.
While I respect your vinegar and baking soda trick Tobias, I’ve found that hydrogen peroxide solutions, store-bought or homemade, can be more effective. Added benefit, it’s also completely pet safe!
Hello Lowell, I’ve also used hydrogen peroxide in the past and can attest to its efficacy. However, I’ve found club soda to be an equally effective and safer alternative, since it doesn’t bleach colored fabrics like hydrogen peroxide can.
I’ve raised more pups than you could shake a stick at and club soda does wonders, does no harm to your carpets or the dog.
