Most dog parents spend a lot of time talking about food, vaccines, supplements, and environmental toxins. But here’s the truth no one loves to hear:
A ton of cancer-linked chemicals are hiding right inside our homes.
Our dogs are even more exposed than we are because they:
live closer to the ground
breathe more air per pound
lick their paws (constantly)
and spend their days rolling around on every surface we clean, spray, or “freshen”
And while social media loves to scream “TOXIC!!!” at everything, very few people offer realistic, affordable alternatives. So let’s fix that.
Below are common household products linked to cancer in people and pets, plus safer swaps that won’t break the bank.
1. Air Fresheners & Scented Candles
What’s the issue?
Those plug-ins and candles that smell like “Ocean Breeze Vacation Sunset”? Yeah… many release benzene, formaldehyde, phthalates, and VOCs - chemicals tied to oxidative stress and chronic illness in dogs.
Healthier alternatives:
Beeswax or coconut-wax candles
Bamboo charcoal odor absorbers
Essential oil diffusers (pet-safe oils only!)
Homemade simmer pots (citrus + herbs = fancy)
Brands I like: Plant Therapy, AnimalEO, and Simply Earth (they send oils + recipes, which makes me feel like an essential-oil chemist). Natural candles tend to be more expensive, but learning how to make homemade candles is a fun and rewarding experience.
2. Household Cleaners & Disinfectants
What’s the issue?
Many conventional cleaners contain chlorine, ammonia, quats, and other chemicals that stick around on surfaces - the same surfaces our dogs walk on… then lick off their paws like a little after-dinner snack.
Healthier alternatives:
DIY cleaner: white vinegar + water + lemon peel + pet-safe essential oils
Truly eco-friendly cleaning brands (just watch out for greenwashing)
Quick note on greenwashing:
Some companies try to look “all-natural and eco-friendly” but aren’t. Thankfully, there are third-party groups that test and verify product claims so you don’t need a chemistry degree.
3. Lawn Chemicals, Weed Killers & Pesticides
What’s the issue?
The big one here is glyphosate - but 2,4-D and other pesticides also show strong links to lymphoma in dogs. Multiple studies confirm dogs living in chemically treated yards have higher cancer risk.
Healthier alternatives:
Pull weeds by hand (free workout!), or mow them down
DIY weed spray: vinegar + salt + a little dish soap
Organic lawn treatments: compost, kelp meal, bone meal, worm castings
Clover or native landscaping (low maintenance, high vibes)
4. Non-Stick Cookware (Teflon)
What’s the issue?
Traditional non-stick pans can release PFAS - “forever chemicals” that build up in the body and mess with hormones. PFAS have even been found in dog blood samples. No thank you.
Healthier alternatives:
Stainless steel
Cast iron
PFAS-free ceramic (my personal choice!)
Carbon steel
Tip: Holiday sales = the best time to upgrade your cookware. Costco has great deals right now.
5. Plastic Food Storage Containers
What’s the issue?
Plastics often contain BPA/BPS and phthalates, which can leach into food - especially if heated. Many dog bowls are also plastic, which adds even more exposure.
Healthier alternatives:
Glass containers
Stainless steel bowls
Silicone lids/wraps
Bamboo lids
What I do:
I’m swapping my plastic out slowly. I wash what I still use by hand to keep it from breaking down, and I grab affordable glass containers from garage sales and holiday sales. My dogs eat from regular human pasta bowls - which are flat enough to avoid scent overload (as in dog bowls) and allow me to spread the food out for pickier eaters.
6. Fabric Sprays & Laundry Products
What’s the issue?
Scented laundry detergents, dryer sheets, and fabric sprays often contain synthetic fragrance, phthalates, and 1,4-dioxane (a known carcinogen).
Our dogs basically live on our laundry piles, blankets, and couches… so yeah, they’re getting a lot of exposure.
Healthier alternatives:
Unscented/fragrance-free detergent
Wool dryer balls
DIY fabric spritz (water + 1 drop lavender or frankincense)
Simple DIY laundry soap (just check ingredients — not all are pet-safe)
7. Flea & Tick Collars and Spot-On Treatments
What’s the issue?
Some popular flea and tick products contain organophosphates and pyrethroids — chemicals linked to neurological issues and cancer. These chemicals can stay on a dog’s fur for weeks.
Healthier alternatives:
Natural repellents (Wondercide, Kin+Kind, essential oil blends)
Regular tick checks
Yard practices like leaf removal, short grass, cedar chips
Immune-supportive foods and mushrooms
About garlic:
Garlic has been unfairly canceled online. The famous “garlic is toxic to dogs” study used ridiculously high amounts of garlic - way more than any normal person would feed. Newer research supports the safe use of garlic in proper doses.
How Much Garlic Can Dogs Safely Eat?
When it comes to garlic, dosage is everything. Too much garlic can lead to hemolytic anemia, especially in sensitive breeds or small dogs. The following are general safe daily garlic guidelines, based on a fresh, raw clove:
Dog's Weight | Garlic Amount |
|---|---|
5–10 lbs | 1/6 clove |
10–15 lbs | 1/4 clove |
20–40 lbs | 1/2 clove |
45–70 lbs | 3/4 clove |
75–90 lbs | 1 clove |
100+ lbs | 1–1.5 cloves |
How to prepare the garlic: Always finely chop and let garlic sit for 10-15 minutes before feeding to activate allicin.
Start with a tiny “loading dose” for 1-2 weeks; then give 2-3x weekly (although it can also be fed daily), followed by a one-week break. This cycling prevents the overaccumulation of sulfur compounds, allowing the body to reset.
Skip garlic spices, powdered or dehydrated garlic, or pre-minced garlic - none of these contain allicin, the compound lauded for its health benefits.
Garlic isn’t safe to use with puppies, pregnant/nursing dogs, or dogs with anemia (or anemic-related health conditions).
What I use: Bug Off by Springtime Supplements.
8. Dry Shampoo, Body Sprays & Personal Fragrances
What’s the issue?
Many contain benzene - a confirmed carcinogen. Dogs inhale it right along with us, and they absorb it through their noses and paws.
Healthier alternatives:
Fragrance-free or essential-oil–based products
Mineral dry shampoo
Natural perfumes without synthetic fragrance
Pet grooming brands I trust:
4-Legger, Project Sudz, Kin+Kind, and Mr. Suzukis.
Why This Matters for Dogs
Dogs:
live close to carpets, grass, and floors
breathe more air per pound
groom themselves nonstop
are more sensitive to chemicals
So even tiny exposures can build up over time. And with cancer rates rising in dogs, reducing their toxic load is one of the most powerful long-term health strategies we have.
My Final Thoughts
When I started learning about all this, I truly thought I’d have to throw out half my house and start a new life in the woods. But thankfully, that’s not necessary.
Just replace products as you run out.
Choose fragrance-free when possible.
Aim for simple, clean ingredients.
Do your best — that’s all any of us can do.
Your dogs (and your own body!) will thank you.
