When we think about creating a healthy home for our dogs, we usually think about good food, clean water, exercise, and regular veterinary care. But there’s another part of your dog’s environment that’s easy to overlook: VOCs in the home.
VOCs, or volatile organic compounds, are chemicals that can evaporate into the air from everyday products. They’re found in everything from cleaning supplies and air fresheners to paints, furniture, flooring, personal-care products, and some pet products.
And because our dogs spend so much of their lives inside our homes, it’s worth paying attention to what they’re breathing, touching, and sleeping around.
What Are VOCs?
Volatile organic compounds are a large group of chemicals that can easily become gases at room temperature. They’re used in thousands of household and consumer products, and many are released into indoor air while products are being used, or even while they’re simply being stored.
The EPA notes that concentrations of many VOCs can be higher indoors than outdoors, sometimes substantially higher. Common household sources include paints, varnishes, cleaning products, disinfectants, pesticides, air fresheners, aerosol sprays, building materials, furnishings, and stored fuels.
Not every VOC is equally harmful. “VOCs” describes a broad category of chemicals, not one specific substance. Some have little known health impact at typical household concentrations, while others are associated with irritation, organ effects, or cancer.
That’s why the specific chemical, and the amount and duration of exposure, matter.
Where Are VOCs Hiding in Your Home?
You may be surprised by how many everyday products can contribute to indoor VOC exposure.
Some common sources include:
-
Air fresheners and scented products: Plug-ins, sprays, scented candles, room sprays, and fragrance products can release VOCs into the air.
-
Cleaning products: Disinfectants, degreasers, carpet cleaners, and other household cleaners may contain volatile chemicals.
-
Paints and finishes: Paint, varnish, stains, adhesives, and solvents can release VOCs, particularly when new.
-
Furniture and flooring: New furniture, carpets, flooring, and building materials can off-gas chemicals into indoor air.
-
Personal-care products: Perfumes, hairsprays, cosmetics, and other fragranced products can contribute to indoor VOC levels.
-
Pesticides: Indoor pest-control products can introduce additional chemical exposures.
-
Pet products: Some beds, toys, crates, grooming products, and other pet items may contain synthetic materials, finishes, adhesives, or fragrances that contribute to chemical exposure.
And here’s something important: a product doesn’t have to smell strongly for it to release chemicals. Odor can be a clue, but it isn't a reliable measure of safety.
Why Should We Care About VOCs and Dogs?
Dogs experience our indoor environments differently than we do.
They spend much of their time close to floors, furniture, carpets, and bedding. They also regularly groom themselves, which means chemicals that settle into household dust can potentially be swallowed.
Their smaller bodies and frequent contact with household surfaces make their everyday environment particularly relevant when we're thinking about cumulative chemical exposure.
Most importantly, emerging research is beginning to show that environmental chemical exposure may have biological consequences in dogs.
A 2025 study published in Veterinary and Comparative Oncology examined dogs participating in the Golden Retriever Lifetime Study. Researchers found increased DNA strand breaks in dogs with lymphoma and higher levels of oxidized DNA in dogs both at diagnosis and during the year before diagnosis. They also found that DNA damage was positively correlated with estimated blood exposure to VOCs including benzene, xylene, and 1,3-butadiene, as well as exposure to certain herbicides.
While this does not mean that VOC exposure causes lymphoma in every dog, it does give us an important reason to pay attention. When environmental chemicals contribute to oxidative stress and DNA damage, reducing unnecessary exposure becomes a reasonable part of a proactive approach to your dog's health.
Benzene: One VOC Worth Knowing About
One chemical that deserves particular attention is benzene.
Benzene can be found in sources such as gasoline, tobacco smoke, and some household products, and it is a known human carcinogen. The EPA recommends minimizing exposure to benzene indoors.
The recent canine research is especially interesting because benzene was one of the VOCs included in researchers' estimates of dogs' environmental exposure.
In other words, everyday chemical exposure isn't just an abstract human health concern. Researchers are now finding measurable relationships between environmental chemical exposure and biological changes in our companion animals.
How Can You Reduce VOC Exposure?
You don't need to throw away everything in your house or become afraid of every chemical... Simply start with the small things and adapt as you go.
Reduce unnecessary fragrance. Skip air fresheners, plug-ins, heavily scented cleaners, and other products whose primary purpose is simply to make your home smell a certain way.
Ventilate. Fresh outdoor air is one of the simplest tools you have. Use exhaust fans and open windows when appropriate, especially when painting, cleaning, or using products that release VOCs.
Filter your air. A properly sized HEPA air purifier can help reduce particulate matter, while activated carbon filtration can help with some gaseous pollutants. Choose filtration appropriate for the specific pollutants you're trying to address.
Pay attention to what your dog sleeps on. Your dog's bed may be one of the products they spend hours in direct contact with every day. Choosing natural, minimally treated materials can be one practical way to reduce unnecessary chemical exposure. Our Woolly Hound natural dog beds are made with organic cotton, wool, and natural latex, without synthetic foam, added flame retardants, or unnecessary chemicals.
Consider your water. Depending on your local water quality, appropriate water filtration may help reduce exposure to certain contaminants.
Use plants as a complement, not your primary air purifier. Pet-safe houseplants can be a lovely addition to your home, but they shouldn't replace ventilation and effective air filtration.
Support your dog's natural detoxification systems. Your dog's liver, kidneys, digestive system, and other biological systems are already designed to process and eliminate many substances. A holistic or integrative veterinarian can help you evaluate your dog's individual nutritional needs and determine whether there are appropriate ways to support normal detoxification and antioxidant defenses.
You Don't Have to Make Your Home Perfect
The goal isn't a completely chemical-free home. That's unrealistic and it can quickly become overwhelming.
Instead, think about reducing unnecessary exposure wherever you reasonably can.
Maybe that means replacing a plug-in air freshener. Maybe it's choosing unscented laundry products, opening a window more often, using an air purifier, or paying closer attention to the materials in your dog's bed.
Small changes can add up.
Key Takeaways
-
VOCs are chemicals released as gases from many everyday household products.
-
Common sources include cleaning products, fragrances, paints, furniture, flooring, pesticides, and some pet products.
-
Dogs can be exposed through the air, household dust, surfaces, and the products they spend time in.
-
New canine research found that oxidative DNA damage and DNA strand breaks were associated with estimated VOC exposure and that some DNA damage was detectable before lymphoma diagnosis.
-
Reducing unnecessary fragrance, improving ventilation, filtering indoor air and water, and choosing thoughtfully made products can help reduce your dog's overall chemical exposure.
-
A holistic or integrative veterinarian can help you develop an individualized approach to nutrition and normal detoxification support.
You can't control every chemical your dog encounters, and you don't need to. But you can take a closer look at the environment you're creating for them.
Because when your dog spends so much of their life inside your home, what's in the air, on the floor, and in the products they use every day matters.
