Whether you’re potty training a new puppy or dealing with unexpected accidents from an older dog, one thing is certain: dog urine smell is unpleasant and persistent. While patience and positive reinforcement are essential for house-training, accidents still happen.
If your already potty-trained dog suddenly starts having accidents, it’s wise to schedule a vet visit to rule out medical issues.
In the meantime, here’s a complete guide to removing dog urine smell from carpets, couches, hard floors, and washable items.
Why Does Dog Pee Smell?
Dog urine contains pheromones, which dogs use to communicate boundaries and mark territory. Unfortunately, once a spot has been marked indoors, these pheromones may encourage repeat accidents.
Bacteria in urine also produce ammonia, which creates the foul odor many pet parents recognize. Even after cleanup, odors can linger. A UV or black light urine detector can help you identify hidden spots for thorough cleaning.
How To Get Rid of Dog Pee Smell
The most effective products are:
- Enzymatic cleaners – Break down the proteins and pheromones in urine, preventing repeat marking.
- Hydrogen peroxide-based cleaners – Neutralize foul odors.
Always test products on a small, hidden area first to ensure they won’t cause damage or discoloration.
How To Get Dog Pee Out of Carpet and Couches
For fabrics and upholstery that can’t go in the wash:
- Blot the area with a towel to absorb excess moisture. Avoid rubbing.
- Apply a hydrogen peroxide-based cleaner with a towel and let sit for 15 minutes (or as directed).
- Blot again with a dry towel.
- Finish with an enzymatic cleaner like Nature’s Miracle or Rocco & Roxie, then blot with a fresh towel.
For heavy or repeated accidents:
- Use a mini wet vac such as the Shark StainStriker with enzymatic cleaner.
- For stubborn stains and odors, call a professional carpet cleaning service.
How To Get Rid of Dog Pee Smell on Hard Floors
- Test a hidden area of your floor with your chosen cleaner.
- Apply a hydrogen peroxide-based cleaner with a soaked towel. Leave it for the recommended time.
- Wipe clean.
- Repeat using an enzymatic cleaner for full odor removal.
How To Clean Rugs, Pillows, Dog Beds, and Sheets
If machine-washable:
- Wash with laundry detergent + enzymatic cleaner.
- Products like Nature’s Miracle Laundry Boost work well for stubborn odors.
If stains or smells remain, use professional dry-cleaning services.
Why Is My Dog Peeing in the House?
Frequent accidents can signal more than just training issues. Possible causes include:
- Fear or anxiety
- Arthritis or mobility issues
- Cognitive decline in senior dogs
- Incontinence
- Overexcitement
- Urine marking
- Health conditions like urinary tract infections
Always consult a veterinarian if accidents are ongoing. If medical issues are ruled out, a certified dog trainer (CPDT) can help with behavior modification.
Accidents are part of life with dogs, but lingering urine smells don’t have to be. With the right cleaning methods and products, you can eliminate odors, prevent repeat marking, and keep your home fresh.
At the same time, always address underlying medical or behavioral causes to ensure long-term success.
