Are air fresheners bad for dogs?

Are air fresheners bad for dogs? It’s a question more Aussie pet owners are asking as their furry mates start sneezing, scratching, or acting a bit off. One minute your lounge smells like “Spring Rain,” the next, your dog’s wheezing like they’ve run a marathon. These scents might freshen up the room, but they could be stirring up trouble for your pup’s lungs and nose.

Vet Dr. Jessica May warns, “Dogs are far more sensitive to airborne chemicals than humans — even a little can trigger a reaction.” Their smaller airways and supercharged sniffers mean they cop the brunt of it, while we barely notice.

In this guide, we’ll sniff out the nasties hiding in common air fresheners, show you which ones to avoid, and help you find safer options that won’t send your dog into a coughing fit. Let’s clear the air — literally — for you and your four-legged mate.

Are Air Fresheners Toxic to Dogs?

Even a spritz of "Ocean Breeze" might come with a hidden price for your pup. Here's what science—and vets—are barking about.

How air fresheners affect canine lungs

Air fresheners release VOCs (volatile organic compounds) and synthetic fragrances into the air, which dogs inhale deeply due to their constant sniffing. These chemicals can irritate canine lungs, trigger asthma-like symptoms, and worsen pre-existing respiratory health issues.

• Dogs have more sensitive airways than humans.

• Chemical inhalation can cause sneezing, coughing, or wheezing.

• Repeated exposure may lead to chronic lung irritation or allergies.

Not all reactions are instant—some build slowly over time, making early signs easy to miss.

Why dogs are more sensitive than humans

Mate, dogs aren’t just small humans in fur coats. Their bodies work differently.

1. Olfactory receptors: Dogs have up to 300 million, humans only 6 million. They breathe in stronger doses of airborne chemicals.

2. Smaller body mass: A puff of scent that’s fine for us can overwhelm a small pup.

3. Detox pathways: Their metabolic systems don’t break down chemicals as efficiently as ours.

That’s why something that smells “clean” to you could be straight-up toxic to them.

Vets’ concerns about indoor air pollution

According to Dr. Elise Berry, a Sydney-based vet, "We’re seeing more cases of unexplained chronic coughing or nasal discharge in dogs—often linked to air freshener exposure."

Veterinarians worry about:

• Long-term effects from indoor air pollutants

• Chronic respiratory issues triggered by household sprays

• Poor ventilation amplifying toxic load

The RSPCA has also flagged the risks of indoor environmental toxins, pushing for awareness around common household chemicals and their impact on animal welfare. Keep your dog's space fresh—but safe.

Toxic Ingredients in Air Fresheners

Not all air fresheners are created equal — and some contain toxic nasties that are more than just unpleasant for your dog. Let’s sniff out the culprits.

Volatile organic compounds (VOCs) explained

VOCs are sneaky chemicals that vaporise at room temp and linger in indoor air. Found in many fresheners, they include formaldehyde and benzene—linked to cancer and respiratory issues in dogs. Poor indoor air quality caused by VOC emissions can irritate your dog’s lungs, especially in enclosed spaces. VOCs are also common in cleaning products, solvents, and building materials, compounding the exposure. While they make homes smell "clean," they’re quietly reducing your pet’s health.

Dangers of phthalates in home scents

Phthalates are added to air fresheners to make scents last longer. But they’re known endocrine disruptors, which means they can mess with hormones.

• May affect reproductive health in both humans and pets

• Linked to asthma and allergy development in dogs

• Often found in scented candles and plug-ins

According to environmental scientist Dr. Leonie Graham, “Prolonged exposure to phthalates is concerning—especially in small pets living indoors full-time.”

What synthetic fragrance really means

“Fragrance” on a label can hide hundreds of chemical compounds—many of them artificial. These mystery mixes often include irritants and allergens, but manufacturers aren't legally required to disclose ingredients. That “fresh linen” smell might be masking health concerns like chronic inflammation, or reactions in dogs with skin or respiratory sensitivities. A whiff of perfume for us? Possibly a migraine—or worse—for your pup.

Preservatives and binders that harm dogs

Let’s break it down. Some air fresheners use the same preservatives and binders found in dodgy pet foods. Dogs may react to:

Small doses over time = big problems. Just like in food, these additives don’t belong near your pet’s snout. Keep it clean, simple, and additive-free.

What Are the Symptoms of Air Freshener Poisoning in Dogs?

Noticed your dog acting odd after you’ve sprayed the room? Some symptoms sneak in quietly but could signal something more serious. Here’s what to watch for.

Breathing changes after scent exposure

Dogs exposed to certain airborne chemicals may start coughing, wheezing, or panting more than usual. That’s often their respiratory system reacting to synthetic fragrances or poor ventilation.

• Symptoms may include:

• Rapid or laboured breathing

• Excessive sneezing or snorting

• Lethargy after room sprays are used

“A dog’s lungs are way more sensitive to inhaled irritants than ours,” says Dr. Elise Cohen, veterinary toxicologist. “Even low-level inhalation can trigger asthma or allergy-like responses in pets.”

Skin irritation linked to home fragrances

Mate, if your dog’s scratching like mad or breaking out in red patches after you’ve cleaned the house or lit a scented candle, your household products could be the culprit.

Many fragrance chemicals—especially in diffusers or plug-ins—can cause topical reactions like:

1. Contact dermatitis – redness and itching on paws or belly

2. Rash – small bumps or inflamed patches under the fur

3. Worsening eczema – especially in dogs already prone to allergies

Steer clear of heavily perfumed cosmetics or cleaners near their beds or toys—they're often more potent than you'd think.

Plug-in vs Spray: Which is Worse?

When it comes to pet health risks, the debate over plug-in air fresheners versus spray air fresheners sparks genuine concern among dog owners. Both release volatile organic compounds (VOCs) that degrade indoor air quality, yet the way they disperse chemicals leads to different impacts on pets.

Veterinary toxicologist Dr. Karen Ellis explains, “Sprays cause an intense burst of chemical exposure, often landing directly on pet bedding or fur, which increases contact irritation. Plug-ins, on the other hand, are constant sources of inhalation hazards, particularly dangerous in poorly ventilated rooms.”

Pet owner Dave Phillips from Brisbane shared his experience: 🗣️ “After we switched to a plug-in, our spaniel Max developed a dry cough within two weeks. It disappeared after we unplugged it.”

Industry tests from the Environmental Working Group (EWG) show that common plug-ins release up to 20 types of VOCs, including benzene and formaldehyde, known irritants that may trigger respiratory irritation in dogs.

🏆 The Australian Pet Health Association recommends:

• Avoiding continuous-release scents in enclosed areas

• Choosing fragrance-free or pet-safe certified products

• Using HEPA air purifiers as alternatives

When selecting between these two, ask: which would I feel safe breathing next to all day? Your dog does not get to choose.

Are Natural or Essential Oil Air Fresheners Safe for Dogs?

Essential oils might smell like a dream, but for dogs, they can be a health nightmare. Let’s break down what’s truly safe and what’s silently harmful.

Toxic essential oils for dogs

Some essential oils are flat-out no-gos for pets. Things like clove, cinnamon, citrus, and pine might seem harmless, but they can cause serious toxicity in dogs.

• Symptoms of poisoning include vomiting, drooling, tremors, and low body temp.

• Even skin contact can cause burns or allergic reactions.

• Oils in diffusers spread particles into the air—your dog can inhale or lick those particles from their coat. Always check with a vet before using any oil around pets.

Risks of diffusing eucalyptus and tea tree

Here’s the thing—tea tree oil and eucalyptus oil might be staples in natural cleaning or relaxation routines, but both are toxic to pets. Even small amounts can spark big problems.

“I’ve seen dogs come in with staggering and drooling just from sniffing diffused tea tree oil,” says Dr. Rachel Hines, vet toxicology specialist.

1. Inhalation can cause coughing, wheezing, and respiratory distress.

2. Liver damage and neurological effects can develop after prolonged exposure or accidental licking.

3. Cats are even more sensitive—but dogs aren’t off the hook either.

Keep these oils well away from your furry mates, especially in enclosed spaces.

Pet-safe herbs vs risky oils

Some plant-based scents can lift your mood and keep your pup safe. Let’s compare a few common ingredients used in aromatherapy and diffusers:

🪴 Tip: Stick to herbs rather than concentrated oils. Use natural remedies like dried lavender satchels instead of plug-in scent bombs.

When in doubt? Call your vet—don’t wing it with your dog's health.
