How to Actually Get Rid of
Pet Odours: Your Complete Guide
From the coat between baths to accidents on the carpet — every odour problem has the right solution. Here's exactly how to find it. 🐾
We love our dogs unconditionally. The smell they occasionally leave behind? A little less so. Whether it's that unmistakable "wet dog" waft from the couch, an accident soaked into the carpet, or a kennel that needs a serious refresh — every pet odour situation is different, and they each need a different kind of product to actually fix it. Here's the honest, practical guide to getting on top of it, with the right tools for every job.
01 — Why Masking FailsWhy Masking Odours Doesn't Work — And What Does
Most household air fresheners and cheap pet deodorisers don't eliminate odours — they coat them in fragrance. For a while, your nose detects the lavender or vanilla rather than the dog. But the odour molecules are still there, lurking beneath the perfume. The moment the fragrance fades — or when moisture reactivates the area — the smell returns, often stronger than before.
The reason pet odours are so persistent is chemistry. Urine, faeces, anal gland secretions, and wet dog smell all involve organic compounds — bacteria, uric acid crystals, ammonia, and volatile organic molecules — that bond to surfaces at the molecular level. You can't rinse or spray them away with fragrance. You need to chemically break them down, neutralise them, or destroy the bacteria producing them at the source.
Uric acid crystals are the real villain. The most stubborn component of pet urine is uric acid — a crystalline compound that binds tightly to carpet fibres, concrete, and fabric. Unlike the other components of urine, uric acid is not water-soluble, which is why a simple clean with soapy water often leaves the smell behind. Worse, when uric acid gets wet again (even from humidity), it re-releases the odour — which is why a carpet that seemed fine in summer suddenly smells in winter. Effective odour eliminators work on contact to neutralise these crystals directly.
Biodegradable surfactants break down organic matter. Products like Odorex combine odour neutralisers with biodegradable surfactants — detergent-like compounds that break the chemical bonds between organic waste molecules and the surfaces they've attached to. This physical disruption, combined with chemical neutralisation, is what permanently eliminates the odour rather than masking it.
Enzyme-based formulas target bacteria. Products using active enzymes (like Plush Puppy Odour Muncher) go one step further: they destroy the bacteria responsible for producing odours in the first place. Rather than covering the smell, they eliminate its biological source — which is why enzyme-based deodorisers produce long-lasting freshness rather than a temporary mask.
Don't mask odours — eliminate them. The difference isn't just philosophical. It's the difference between a spray that lasts 20 minutes and one that means you never smell that spot again.
The Right Product for Every Odour Situation
Not all pet odour products are designed for the same job. Using the wrong one doesn't just fail — it can sometimes make things worse (some cleaning products can actually set urine stains). Here's a straightforward guide to which situation calls for which approach:
-
Your dog smells between baths
This is where a coat deodoriser like Plush Puppy Odour Muncher excels. A light mist over the coat doesn't just perfume your dog — its active enzyme formula targets the bacteria on the coat and skin that cause the "doggy smell". Safe for all breeds and coat types, it doesn't inhibit natural transpiration or disrupt skin flora. A little goes a very long way. Perfect between grooming appointments or after your dog has been rolling in something they found delightful.
-
The couch, car, or bedding smells like dog
Again, the Plush Puppy Odour Muncher is your friend here — a light mist over fabric surfaces works on contact to neutralise the odour-causing bacteria that have transferred from your dog's coat. It's safe on upholstery, carpets, car interiors, and dog bedding. For heavier soiling or a persistent smell from an accident, step up to the Odorex Animal Odour Eliminator for a direct application that neutralises at the source.
-
There's been an accident on carpet or flooring
This is where targeted odour elimination matters most. Odorex Animal Odour Eliminator (450ml spray) is designed specifically for this — a non-toxic, biodegradable formula that works on contact to permanently neutralise urine, faeces, vomit, and anal gland secretion. Blot up excess liquid first, then saturate the affected area. Crucially: enough product must reach the source of the odour, not just the surface. For carpets, this means soaking the area so the formula penetrates to the underlay where the uric acid crystals live.
-
Large areas, kennels, runs, or repeat accidents
For ongoing situations, large outdoor or indoor areas, or pet care facilities, the Odorex Pet Clean Up Concentrate (1L) is the most economical and powerful solution. One litre dilutes to 25 litres of professional-strength cleaner — combining deodorising agents, biodegradable detergent, antibacterial agents, and a pleasant fragrance. It handles urine, faeces, and all animal odour problems on contact. Can be mopped, sprayed, or water-blasted onto surfaces, or added to the rinse cycle when washing animal bedding.
-
Puppies in toilet training
Odour elimination during puppy toilet training does double duty: it removes the smell for your benefit and removes the chemical marker that tells your puppy "this spot is a toilet." Dogs return to spots they've soiled before because their keen nose can still detect uric acid traces that we can't. Properly neutralising every accident spot with Odorex breaks this cycle and genuinely accelerates toilet training progress.
Our Odour-Busting Range at Thorncombe
Three products, three distinct jobs — here's what each one does and when to reach for it:
Plush Puppy Odour Muncher Coat Deodoriser
The dog grooming world's favourite coat deodoriser — and once you try it, you'll understand why. Active enzymes literally munch the odour-causing bacteria on your dog's coat rather than masking the smell with fragrance. A light mist over the coat or any surface where your dog has been leaves a genuinely long-lasting freshness. Available in Original (masculine overtones) and Fresh (sweet forest scent). Suitable for all breeds and coat types, and safe to use on bedding, furniture, carpets, kennels, and car interiors. A little goes a long way — this is not a dog perfume, it's a proper deodorising system that just happens to smell great.
Odorex Animal Odour Eliminator 450ml
New Zealand's most trusted pet odour eliminator — and the one recommended by vets, groomers, and breeders across the country. Non-toxic, biodegradable, and NZ made, it works on contact to permanently neutralise odours from urine, faeces, vomit, anal gland secretion, wet dog smell, and more. Not a mask — a permanent elimination. Safe to use around pets and people, and can be used as an air freshener. Ideal for carpet accidents, furniture, litter trays, puppy toilet training areas, and anywhere a smell has taken hold. The 450ml spray bottle is the perfect everyday household size.
Odorex Pet Clean Up Concentrate 1L
The professional-grade solution for large areas, ongoing situations, and serious odour problems. One litre makes 25 litres of ready-to-use cleaner — combining professional-strength deodorising concentrate, biodegradable detergent, antibacterial agents, and a pleasant fragrance into a single powerful formula. Originally developed for kennels and catteries (it was previously called Odorex Kennel Cleaner Concentrate), it's now widely used by Kiwi pet owners for anything from washing pet bedding to treating entire rooms, outdoor runs, artificial grass, and cages. Apply by mop, spray, or water blaster — or add to the rinse cycle when washing bedding. Extraordinary value at less than $2 per litre when diluted.
Pro Tips for a Genuinely Fresh Home
Find hidden odours with a UV torch
Pet urine fluoresces under UV (blacklight) — meaning you can find dried stains that are completely invisible in normal light. If you're struggling with a persistent smell you can't locate, a UV pet stain detector torch will reveal every spot that needs treatment. Game-changing for carpet situations.
Soak the source, not just the surface
The single most common reason odour eliminators "don't work" is insufficient application. Odour neutralisers work on contact — so they must physically reach the source of the smell. For carpet accidents, this means using enough product to soak through to the underlay. A superficial spray often treats the top of the fibre while the uric acid crystals underneath remain untouched.
Add concentrate to your bedding wash
The Odorex Pet Clean Up Concentrate can be added directly to the rinse cycle when washing dog bedding, blankets, and towels. This eliminates odours that survive a standard wash cycle and leaves everything genuinely fresh — not just clean-smelling while wet and doggy-smelling once dry.
Treat, dry, and retreat if needed
For older or heavily saturated stains, a single treatment may not fully resolve the issue — especially if the odour has penetrated multiple layers. Allow the area to dry completely between treatments, then assess. Persistent odours usually resolve with a second thorough application that targets any source the first treatment missed.
Use the Muncher between appointments
Professional groomers use Odour Muncher as a finishing spray — and you can use it the same way at home. A light mist after your dog's bath extends freshness for days. Use it again mid-week when the coat starts to smell and you're not ready for another full bath. Your dog stays fresh; your couch stays fresh.
Regular maintenance beats emergency treatment
A weekly spray of diluted Odorex Concentrate on high-traffic dog areas — the laundry, the kennel, the back of the car — prevents odour build-up before it becomes a problem. Reactive treatment of a well-established smell is harder than maintenance prevention. A quick weekly spray takes 60 seconds and costs cents.
🌿 A note on safety
All three products featured in this guide are non-toxic and safe to use around pets and people when used as directed. Odorex products are biodegradable and NZ made. Always spot-test delicate fabrics before use, allow treated areas to dry before allowing pets back in contact, and keep all products out of reach of children. For the Concentrate, use the recommended 1:25 dilution — more is not more effective, just wasteful.
Frequently Asked Questions
Why does my carpet smell after I've already cleaned it?
Almost certainly because uric acid crystals from pet urine are still present beneath the surface. Standard cleaning products and even steam cleaning cannot break down uric acid — it needs a purpose-built odour eliminator applied in sufficient quantity to soak through to the source. Once dry, humidity or re-wetting can reactivate the crystals and release the smell. Treat with Odorex Animal Odour Eliminator, saturating the area thoroughly, and allow to dry completely.
Is Odour Muncher safe to spray directly on my dog?
Yes — Plush Puppy Odour Muncher is specifically formulated for direct application to a dog's coat. It does not inhibit natural transpiration or interfere with the natural flora of the skin. Mist lightly over the coat and it's safe to leave in without rinsing. Suitable for all breeds and coat types. Avoid contact with eyes.
Can I use the Pet Clean Up Concentrate full-strength for tough jobs?
No — the concentrate is designed for use at a 1:25 dilution (1 part concentrate to 25 parts clean water) for all standard applications. Using it undiluted won't improve results and may damage delicate surfaces. For very tough odours, apply the correctly diluted solution generously and allow adequate dwell time to reach the source, rather than using a stronger concentration.
Which product should I use first for a fresh accident?
Blot up as much liquid as possible with paper towels or a cloth — without rubbing, which spreads the stain. Then apply Odorex Animal Odour Eliminator generously, ensuring it soaks through to the same depth the urine reached. Allow to air dry. Don't use any other cleaning products before the Odorex — some common cleaners (especially those containing ammonia) can actually make pet odours worse or set stains permanently.
Can I use the Concentrate on artificial grass?
Yes — Odorex Pet Clean Up Concentrate is ideal for artificial grass, which is notorious for trapping and concentrating animal odours. Apply the diluted solution by spray or water blaster and allow to dry. Regular treatment (weekly for a busy dog) will prevent odour build-up entirely. It's the product used by boarding kennels and doggy daycares across NZ for exactly this reason.
