Plants Safe for Dogs: 12 Non-Toxic Houseplants (ASPCA-Verified)
By Ellen Hermance · PlantCareAI Editorial
Dogs chew things — including houseplants. Many common houseplants are toxic to dogs, causing vomiting, diarrhea, organ damage, or worse. The ASPCA Animal Poison Control Center handles tens of thousands of plant-related pet toxicity calls each year. Choosing non-toxic plants from the start eliminates this risk entirely. This guide covers 12 ASPCA-verified dog-safe houseplants with care notes for each.
Quick Answer: Dog-safe houseplants include Spider Plant, Boston Fern, Areca Palm, Calathea, Orchid, Peperomia, Haworthia, Bromeliad, African Violet, Catnip, Swedish Ivy, and Snapdragon. All confirmed non-toxic to dogs by the ASPCA. Avoid Sago Palm (deadly), Tulip bulbs, Azalea, and Oleander — all highly toxic.
12 Non-Toxic Plants Safe for Dogs
-
Spider Plant (Chlorophytum comosum)
Spider plants are non-toxic to dogs. They're one of the most widely available and easy-care houseplants, making them a practical choice for dog households. Dogs occasionally chew the trailing runners, which causes no harm.
How to fix it: Care: bright to moderate indirect light, water when top inch of soil is dry. Spider plants tolerate irregular watering and low light better than most plants. Excellent for beginners.
-
Boston Fern (Nephrolepis exaltata)
Boston ferns are confirmed non-toxic to dogs. Their feathery, arching fronds make them one of the most attractive hanging basket plants. Dogs may chew fronds without any toxic risk.
How to fix it: Care: high humidity, indirect light, consistently moist soil. Best in bathrooms or kitchens where humidity is naturally higher. Mist the fronds every few days or use a pebble humidity tray.
-
Areca Palm (Dypsis lutescens)
Areca palms are non-toxic to dogs and one of the best large statement plants for pet households. They're also natural air humidifiers. Their graceful, arching fronds add significant visual presence.
How to fix it: Care: bright indirect light, water when top 2 inches of soil are dry. Use filtered water to prevent fluoride tip burn. Can grow 6–8 feet tall indoors. Repot every 2–3 years as roots fill the pot.
-
Calathea (Calathea spp.)
Calatheas are non-toxic to dogs. Their dramatic patterned leaves — stripes, spots, and watercolor-like markings — make them among the most decorative houseplants available. Completely safe if a dog chews on them.
How to fix it: Care: indirect light, even moisture, humidity above 50%. Leaves curl when thirsty or stressed. Use filtered or distilled water — calatheas are sensitive to fluoride and chlorine. Keep away from cold drafts.
-
Orchid (Phalaenopsis spp.)
Phalaenopsis orchids are non-toxic to dogs. They're elegant, long-blooming (2–4 months per bloom cycle), and widely available. If a dog chews the leaves or flower spike, mild stomach upset may occur but no serious harm.
How to fix it: Care: bright indirect light, water once a week by soaking and draining, do not let roots sit in water. Repot in orchid bark every 1–2 years. Rebloom by placing in a cooler spot (60–65°F) for 4 weeks.
-
Peperomia (Peperomia spp.)
All Peperomia species are non-toxic to dogs. With over 1,000 species spanning textures from waxy to velvety to ridged, Peperomia is one of the most diverse and dog-safe genera. Their compact size makes them easy to manage around dogs.
How to fix it: Care: moderate indirect light, water when the top inch of soil is dry (thick leaves store water — overwatering kills them). Very drought-tolerant. Great windowsill plant.
-
Haworthia (Haworthia spp.)
Haworthia is a safe succulent for dog households — unlike Aloe Vera (toxic to dogs), Haworthia is confirmed non-toxic. It has a similar rosette shape to aloe but stays small and is very low-maintenance.
How to fix it: Care: bright indirect light (avoid harsh direct afternoon sun), water every 2–3 weeks, excellent drainage essential. Tolerates drought well. Perfect for windowsills and desks.
-
Bromeliad (Bromeliaceae family)
Bromeliads are non-toxic to dogs. They're long-lasting, low-maintenance, and produce vivid tropical colors through their bracts. Dogs can safely interact with them.
How to fix it: Care: bright indirect light, fill the central cup with water and change it weekly to prevent stagnation, mist occasionally. After blooming, the main plant produces pups (offshoots) you can repot.
-
African Violet (Saintpaulia spp.)
African violets are non-toxic to dogs. They're compact, bloom almost continuously in good conditions, and come in purple, pink, white, and bicolor varieties. Safe even if a dog chews the velvety leaves.
How to fix it: Care: bright indirect light (east window ideal), water from below to avoid leaf spotting, keep soil slightly moist. Feed with bloom-booster fertilizer monthly. Avoid cold windowsills in winter.
-
Catnip (Nepeta cataria)
Catnip is non-toxic to dogs. Unlike the dramatic response in cats, dogs don't have the same receptor for nepetalactone, so it doesn't affect them the same way. A dog may sniff or chew it without any harm.
How to fix it: Care: full sun (4–6 hours), well-draining soil, water when top inch is dry. Grows vigorously. Can be used as a dog-safe companion plant near other houseplants — though dogs generally ignore it.
-
Swedish Ivy (Plectranthus verticillatus)
Swedish ivy is non-toxic to dogs. It's a fast-growing trailing plant with scalloped leaves that cascades attractively from hanging baskets. Not a true ivy — English ivy (Hedera helix) is toxic to dogs.
How to fix it: Care: bright to moderate indirect light, let soil dry slightly between waterings, mist occasionally. Pinch growing tips to maintain a bushy shape. Easy to propagate in water.
-
Snapdragon (Antirrhinum majus)
Snapdragons are non-toxic to dogs and make cheerful indoor plants when given enough light. They're more commonly grown outdoors but can be kept as indoor container plants in bright conditions. Safe if chewed.
How to fix it: Care: full sun (at least 6 hours) or bright grow light, cool temperatures preferred (55–65°F ideal), water when top inch is dry. Best treated as seasonal — buy in bloom and enjoy, then compost.
Safe vs. Toxic Common Houseplants for Dogs

Frequently Asked Questions
- Is Aloe Vera safe for dogs?
- No. Aloe Vera is toxic to dogs. The saponins and anthraquinones in aloe cause vomiting, diarrhea, lethargy, and in large amounts, tremors. The gel used medicinally for humans is processed to remove these compounds, but the raw plant is dangerous. Use Haworthia as a safe lookalike alternative.
- Are Succulents safe for dogs?
- Some are, some aren't. Haworthia and Echeveria are non-toxic to dogs. Aloe Vera, Euphorbia (including Pencil Cactus), and Kalanchoe are toxic. Always verify by genus — 'succulent' covers thousands of species with different toxicity profiles.
- Is Pothos safe for dogs?
- No. Pothos contains insoluble calcium oxalate crystals that cause oral burning, drooling, vomiting, and difficulty swallowing in dogs. Keep Pothos well out of reach or replace with a dog-safe trailing plant like Swedish Ivy.
- What plants are most dangerous for dogs?
- The most dangerous plants for dogs include Sago Palm (cycasin causes fatal liver failure — even one seed can kill a dog), Oleander (cardiac glycosides), Azalea/Rhododendron (grayanotoxins), and Yew (taxines). For houseplants, Dieffenbachia, Philodendron, and Peace Lily cause severe oral injury. Tulip and Daffodil bulbs are also highly toxic.
- What should I do if my dog eats a plant?
- Call the ASPCA Animal Poison Control Center (888-426-4435) or your vet immediately if you're unsure whether the plant is toxic. Do not induce vomiting unless a vet instructs you to. Bring a photo or sample of the plant to the vet. For non-toxic plants, monitor for mild digestive upset (vomiting, loose stools) that should resolve within 24 hours.
- Are Peace Lilies safe for dogs?
- No. Peace Lilies are toxic to dogs, containing calcium oxalate crystals that cause oral burning, drooling, and vomiting. They're one of the most common toxic houseplants. Replace with Calathea — it has similar bold, tropical foliage and is completely dog-safe.
The Bottom Line on Dog-Safe Plants
For dog households, choose plants from ASPCA-verified non-toxic lists and place all others out of reach or outside the home. Spider Plant, Boston Fern, Calathea, Orchid, and Peperomia are the most reliable and widely available dog-safe options. The plants most worth avoiding: Sago Palm (can be fatal from a single seed), Oleander, Azalea, Dieffenbachia, and Peace Lily. When in doubt, check the ASPCA's complete plant toxicity database before buying anything new.
