If you've got dogs and plants in the same house, you've probably worried about this at least once. Most dogs aren't actively trying to eat the houseplants, but a curious nose, a bored puppy or a dropped leaf can change that quickly.
The good news: plenty of beautiful indoor plants are non-toxic to dogs. The better news: the list of genuinely dangerous indoor plants is shorter than most people think. Once you know which ones to watch out for, the rest is mostly about positioning and species selection.
One thing worth saying upfront: dogs vary. Some never touch plants. Some chew everything within reach, especially as puppies. Bigger dogs reach plants that smaller dogs can't. Even a non-toxic plant can cause mild stomach upset if eaten in quantity — and some dogs will happily eat enough of anything to find out. Keep that in mind as you read.
The plants to know about first — common toxic ones
Before the safe list, here are the plants that come up most often in dog toxicity cases. If you have any of these, consider where they're positioned:
Sago Palm (Cycas revoluta) — the most serious one. Highly toxic to dogs and can be fatal even from small amounts. Symptoms include vomiting, diarrhoea, seizures and liver failure. If you have dogs, avoid Sago Palms entirely. The seeds are the most toxic part but the whole plant is dangerous.
Pothos / Devil's Ivy (Epipremnum aureum) — contains calcium oxalate crystals. Can cause significant oral irritation, drooling, vomiting and difficulty swallowing if chewed. Very common indoor plant — worth keeping out of reach of persistent chewers.
Monstera deliciosa — same calcium oxalate issue as Pothos. Not typically fatal, but uncomfortable. Most dogs learn quickly to leave it alone after one experience.
Peace Lily (Spathiphyllum) — calcium oxalates again. Despite its gentle reputation and the "lily" in the name, it isn't a true lily, but it can still cause significant oral irritation.
Dieffenbachia — also known as Dumb Cane for good reason. The calcium oxalate concentration is high enough to cause severe oral pain, swelling and difficulty swallowing.
ZZ Plant (Zamioculcas zamiifolia) — calcium oxalates. Generally considered low toxicity but can cause GI upset if eaten.
Dracaena — toxic to dogs. Can cause vomiting (sometimes with blood), drooling, lethargy and loss of appetite.
Aloe Vera — contains saponins that can cause lethargy, vomiting and diarrhoea when eaten in significant amounts. The medicinal benefits for humans don't translate.
English Ivy (Hedera helix) — toxic to dogs. Can cause hypersalivation, vomiting, diarrhoea and abdominal pain.
If your dog eats any plant and shows signs of distress — vomiting, drooling, lethargy, loss of appetite, difficulty breathing — contact your vet. This list is a guide, not a substitute for professional advice.
The safe list — 10 dog-friendly indoor plants
These are all considered non-toxic to dogs by the ASPCA. That doesn't mean unlimited snacking is encouraged — any plant material can cause mild GI upset in quantity — but these won't cause serious harm if your dog has a chew.
1. Spider Plant (Chlorophytum comosum)
One of the most forgiving indoor plants going — tolerates low light, irregular watering and general neglect. The long arching leaves look great trailing from a shelf, well out of dog reach, and are entirely safe if a leaf gets pulled down. Spider Plants are also one of the easiest plants to propagate, so a chewed one can easily become several new plants.
Water when the top 2-3cm of mix is dry. Feed every two weeks during active growth.
2. Parlour Palm (Chamaedorea elegans)
Elegant, feathery fronds, tolerates lower light better than most palms, and completely non-toxic to dogs. A genuinely underrated plant — it doesn't need direct sun and handles the humidity of most indoor environments without complaint. Its upright habit also means it can stand at floor level without offering tempting trailing leaves.
Water when the top few centimetres of mix feel dry. Feed lightly through spring and summer.
3. Boston Fern (Nephrolepis exaltata)
Lush, dense fronds and entirely safe for dogs. Boston Ferns like humidity and indirect light — a bathroom with a window is often ideal. They'll tell you when they're unhappy by dropping fronds, which makes them useful self-reporters. If a dropped frond gets investigated by a curious dog, no harm done.
Keep the mix slightly moist and avoid direct sun. In very dry rooms, increasing ambient humidity helps more than misting.
4. African Violet (Saintpaulia)
Small, compact, and one of the few flowering houseplants on this list. Non-toxic to dogs and rarely large enough to be a serious chewing target. Likes bright indirect light and consistent moisture — water from the bottom (the leaves don't appreciate water on them) and keep the mix consistently damp without going waterlogged.
A good choice for dog households that want some flowers without the risk of true lilies or other flowering plants that are toxic.
5. Chinese Money Plant (Pilea peperomioides)
The circular leaves and quirky upright growth habit make this one of the more distinctive plants on the list. Non-toxic to dogs, easy to propagate (it produces offshoots regularly that can be separated into new plants), and happy in moderate indirect light.
Water when the top 2-3cm of mix is dry. Rotate regularly so it doesn't lean toward the light.
6. Cast Iron Plant (Aspidistra elatior)
Named for good reason. The Aspidistra survives lower light, irregular watering and general neglect — it was the quintessential Victorian parlour plant precisely because it could handle gas-lamp fumes and dim rooms. Non-toxic to dogs and robust enough to tolerate a bit of investigation from a curious one.
Water when the top half of the mix is dry. Feed lightly through the growing season.
7. Ponytail Palm (Beaucarnea recurvata)
Not actually a palm — it's a succulent with a bulbous water-storing base and long arching leaves. Extremely low maintenance, tolerates irregular watering well, and non-toxic to dogs. Sits well at floor level for most setups without being especially appealing to most dogs.
Bright light, infrequent watering, well-draining mix. Err on the dry side.
8. Rattlesnake Plant (Goeppertia lancifolia, formerly Calathea lancifolia)
Intricately patterned leaves with deep green markings and purple undersides — and the characteristic habit of raising and lowering leaves from day to night. Non-toxic to dogs. Likes humidity, indirect light and consistently moist (not wet) mix.
Note the taxonomy update: most plants sold as Calathea have been reclassified as Goeppertia. Same plant, different name on the label.
9. Bird's Nest Fern (Asplenium nidus)
Glossy, ripple-edged fronds that radiate from a central rosette — big jungle vibes without any of the risks. Non-toxic to dogs and well-suited to lower light and humid conditions. A good bathroom or kitchen plant.
Keep the mix slightly moist, avoid getting water in the central rosette, and keep out of direct sun.
10. Staghorn Fern (Platycerium bifurcatum)
Mounted on a piece of timber and hung on a wall, a Staghorn Fern is one of the most dramatic-looking indoor plants you can grow — and conveniently out of reach of most dogs. Non-toxic, likes bright indirect light and prefers to be watered by soaking rather than from above.
A particularly good option for dog households — wall-mounted plants solve the positioning problem entirely.
Living with dogs and plants — a few practical notes
Species selection gets you most of the way there. Positioning gets you the rest.
Dogs reach plants differently than cats. Cat-proofing usually means putting plants up high. Dog-proofing means putting plants where the dog doesn't go — high shelves work, but so do rooms with closed doors, plant stands the dog can't access, and hanging planters mounted out of jumping range. Bigger dogs can reach higher than people expect; if you've got a large breed, anything below shoulder height is potentially accessible.
Watch for dropped leaves. The actual risk is often a fallen leaf on the floor, not the plant on the shelf. Dogs investigate ground-level objects far more than wall-mounted or elevated ones. Pick up dropped leaves promptly, particularly from any of the toxic plants listed above.
Puppies are the riskiest stage. Most adult dogs ignore plants entirely. Puppies investigate everything with their mouths — and they're easier to redirect than to restrict. If you're bringing a puppy into a plant-filled home, treat every plant as accessible for the first 6-12 months until the chewing phase settles. Providing dog-safe chew toys and enrichment reduces interest in plants significantly.
Outdoor access matters too. This guide focuses on indoor plants, but if your dog has yard access, the most dangerous plants are often the ones planted outdoors — Sago Palms again, plus oleander, foxglove, daffodil bulbs, tulip bulbs, and azaleas. Worth being aware of what's in your garden as well as your living room.
If your dog eats something and you're not sure whether it's safe, the ASPCA Animal Poison Control Center (US) and the Australian Veterinary Association are good starting points. When in doubt, call your vet.
