Finding plants safe for dogs comes down to one authoritative source — the ASPCA Toxic and Non-Toxic Plants database — and this list pulls 13 non-toxic-to-dogs species from it that are worth buying, with care notes for each and a short list of popular plants that look safe but aren't.

What "non-toxic to dogs" actually means

Before the list: a clarification that most articles skip.

The ASPCA doesn't formally define "non-toxic." Its plant list describes plants "listed as either non-toxic, or potentially toxic with mild GI upset" as ones whose symptoms "are not expected to be life-threatening to your pets." It does not mean:

  • The plant is safe to eat. Any plant material — even "safe" plants — can cause vomiting, diarrhea, or gastrointestinal upset in dogs, especially if they eat large quantities.
  • The plant won't cause an allergic reaction. Individual dogs have individual sensitivities.
  • All species in the genus are covered. Some ASPCA entries are genus-level (Calathea spp. is one), but many list a single species, so check the exact plant you're buying.
  • Your dog won't chew it into pieces anyway, regardless of toxicity.

The practical implication: "non-toxic" plants are significantly safer to have around dogs than toxic ones. They won't cause the liver failure of sago palm or the cardiac arrhythmias of oleander. But "non-toxic" is not a license to let your dog eat the houseplants. Keep all plants out of reach if your dog is a chewer.

For the toxic plants your dog might encounter, the ASPCA Animal Poison Control Center is at (888) 426-4435, 24/7. See also our pet-safe plant directory for the full verified list across all species. If you also have cats, see our cat-safe plants list.

Prayer plant (Maranta leuconeura) is not on this list. The ASPCA's Prayer Plant entry lists that plant as non-toxic, but its scientific name is Calathea insignis, a different species, and no ASPCA entry found names Maranta leuconeura. See are prayer plants toxic to cats and dogs?

1. Spider Plant (Chlorophytum comosum)

Difficulty: Very easy

Spider plants are the correct first recommendation for dog households — easy enough for anyone, propagates easily by plantlets or division (NC State Extension) so a chewed plant is easily replaced, and confirmed non-toxic to cats and dogs by the ASPCA. One honest note: cats are often drawn to chew spider plants (claims of a hallucinogenic effect are widely repeated but uncited). For dogs, they're just foliage. See spider plant care.

2. Boston Fern (Nephrolepis exaltata)

Difficulty: Moderate

Boston ferns are beautiful, genuinely striking when well-maintained, and confirmed non-toxic to cats and dogs by the ASPCA. The catch is the care demand: they want consistently moist soil and high humidity (MBG), meaning they need regular checking. A dog household bathroom or a humid kitchen is the best placement. See Boston fern care.

3. Calathea (Calathea spp.)

Difficulty: Moderate

Calatheas are the most visually impressive non-toxic plants available for dogs. The patterned foliage — deep green with contrasting light green, white, pink, or maroon — is genuinely decorative in a way that most "safe" plants aren't. The ASPCA lists the Calathea genus as non-toxic to cats and dogs.

The care requirements: high humidity (NC State Extension suggests a tray of wet pebbles), filtered or off-gassed water to prevent brown tips from fluoride, and medium indirect light. If you can meet those conditions, the reward is some of the best-looking houseplant foliage available. See Calathea orbifolia care.

4. Cast Iron Plant (Aspidistra elatior)

Difficulty: Very easy

The cast iron plant is the best option for genuinely dim spaces where you have dogs and want something that tolerates real low-light conditions. Non-toxic to cats and dogs per the ASPCA, slow-growing, and forgiving of neglect. It's not exciting, but if the need is "something alive in a dark corner of a dog household," this is the answer.

5. African Violet (Saintpaulia ionantha)

Difficulty: Moderate

African violets are small, flowering, and non-toxic to cats and dogs per the ASPCA. The deep green fuzzy leaves and purple, pink, or white flowers are a cheerful presence on a windowsill. The key care rule: never get water on the leaves (it causes spots). Bottom-watering — placing the pot in a saucer of water and letting it drink from below — prevents this. African violets want bright indirect light, which a north-facing windowsill with no obstructions provides adequately.

6. Parlor Palm (Chamaedorea elegans)

Difficulty: Easy

Parlor palms are non-toxic, low-light tolerant, and provide the structural element (height, architectural form) that many of the smaller plants on this list don't. A parlor palm on the floor in a corner, or on a plant stand, fills space in a dog household where taller toxic plants like dracaena, snake plant, or fiddle leaf fig would be off-limits. See parlor palm care.

The ASPCA's "Bamboo Palm" and "Reed Palm" entries are also Chamaedorea elegans. It has no entry for Chamaedorea seifrizii, another palm sold as bamboo palm, so that species is not on this list.

7. Areca Palm (Dypsis lutescens)

Difficulty: Easy

The areca palm (also called golden butterfly palm) is larger than the parlor palm and non-toxic to cats and dogs per the ASPCA. It needs more light than the parlor palm (bright indirect light per NC State Extension, preferably near a bright east or south window) but rewards that placement with full, feathery growth. An areca palm in a bright dog-household living room fills the "large statement plant" role without the toxicity risk of fiddle leaf figs or dracaenas.

8. Aluminum Plant (Pilea cadierei)

Difficulty: Easy

Aluminum plants have striking silver-and-green patterned leaves that look good enough to be mistaken for something more demanding. They're confirmed non-toxic to cats and dogs by the ASPCA, grow at a satisfying pace, and stay compact enough for windowsills or shelves. The main care need: pinch back the growing tips occasionally to keep the plant bushy rather than leggy. See aluminum plant care.

9. Ponytail Palm (Beaucarnea recurvata)

Difficulty: Very easy

The ponytail palm looks like it belongs in a Frank Lloyd Wright house — the swollen base, the fountain of thin leaves at the top, the sculptural form. It's drought-tolerant (that swollen base stores water) and non-toxic to cats and dogs per the ASPCA, which lists it as Pony Tail.

The one requirement it can't compromise on: bright light. It needs a sunny window, per NC State Extension, such as a south- or east-facing one. A dim corner kills it slowly.

10. Nerve Plant (Fittonia verschaffeltii)

Difficulty: Moderate

Nerve plants have the most decorative foliage per dollar of any plant in this category — the fine veining pattern in white, red, or pink against deep green is genuinely beautiful, and they're small enough to sit on any surface. Non-toxic to cats and dogs per the ASPCA. The challenge: they wilt dramatically if the soil dries out, and they need humidity. In a bathroom with dogs or a kitchen with a pebble tray, they're manageable.

11. Christmas Cactus (Schlumbergera × buckleyi)

Difficulty: Easy

Christmas cacti are non-toxic to cats and dogs per the ASPCA (which files them under Schlumbergera bridgesii) and one of the only flowering cactus-family plants that genuinely thrives indoors. They bloom in winter (December to February, per NC State Extension), producing tubular flowers in red, pink, white, or purple, and they're one of the more forgiving plants in this category. NC State notes that flowering needs night temperatures of 55 to 65°F and at least 13 hours of uninterrupted darkness.

12. Watermelon Peperomia (Peperomia argyreia)

Difficulty: Easy

The watermelon peperomia has striped leaves that genuinely look like a watermelon rind — silver-green stripes on dark green, with a red stem. It's compact, growing up to 8 inches tall per NC State Extension, and is confirmed non-toxic to cats and dogs by the ASPCA. It handles indirect light well. An excellent, low-effort small plant for windowsills in dog households.

13. Phalaenopsis Orchid (Phalaenopsis spp.)

Difficulty: Moderate

Phalaenopsis orchids are the most elegant flowering plants available for dog-safe homes. The ASPCA lists Phalaenopsis (moth) orchids as non-toxic to dogs and cats. Their flowers can last four months or more, per NC State Extension, and they come in a wide range of colors with a minimalist form that suits modern homes. The care protocol is simple once you know it: weekly watering for mature plants, by running the pot under tap water; bright indirect light (NC State calls an east windowsill the best placement); and regular fertilizing, which NC State suggests as a balanced fertilizer twice monthly at half strength.

Common plants that look safe but aren't

Peace Lily — Often recommended in "safe for pets" articles because of its "clean" appearance. Toxic to dogs and cats via insoluble calcium oxalates per the ASPCA. Keep it out of reach.

Pothos — The most popular trailing houseplant. Toxic to dogs and cats per the ASPCA. If you want a trailing plant in a dog household, stick to a spider plant instead.

Snake Plant — Frequently listed as a low-maintenance "safe" plant. Toxic to dogs and cats (saponins) per the ASPCA. The classic "just ignore it" plant recommendation belongs on a high shelf out of chewing range.

Jade Plant — Toxic to cats and dogs per the ASPCA. Keep it elevated.

Aloe Vera — Often kept in homes as a first-aid plant. Toxic to cats and dogs per the ASPCA.

How to choose between these picks

If light is limited (north-facing window or dim apartment), your best choices are: Cast Iron Plant (truly dim conditions), Parlor Palm (medium-low), Spider Plant (medium-low), or Calathea.

If easy care is the priority, go Spider Plant, Cast Iron Plant, Ponytail Palm, Christmas Cactus, or Areca Palm. All five tolerate occasional neglect.

If you want the best-looking plant for a dog household, Calathea and Phalaenopsis Orchid are the aesthetic standouts. Both require more attention but reward it with genuinely decorative foliage or flowers.

If you want a large floor plant in a dog household, Areca Palm fills that role without the toxicity risks of dracaenas, fiddle leaf figs, or snake plants.

FAQ

Is the ASPCA database complete? Should I trust it as the only source?

The ASPCA database is the most comprehensive publicly available English-language resource for pet plant toxicity. It's based on reported cases and published veterinary literature. It has gaps — plants without entries haven't necessarily been tested, and absence of a listing is not confirmation of safety. This list uses it as the primary source and flags when a plant has no ASPCA entry, using NC State, University of Illinois Vet Med, and Missouri Botanical Garden as fallbacks. Where no primary source confirms safety, the list says so.

My dog chewed a non-toxic plant. Should I call poison control?

If your dog chewed a plant and is showing symptoms — vomiting, diarrhea, excessive drooling, lethargy, tremors — call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 regardless of what the plant was. "Non-toxic" means the plant hasn't been associated with serious systemic toxicity, not that it causes zero reaction in every dog.

What if I don't know what plant I have?

Don't assume it's safe. If you have an unidentified plant and a dog that chews things, either identify the plant first (a combination of PlantNet app and confirming against the ASPCA database) or keep it out of the dog's reach until you do.
