Dogs explore yards and living rooms with their mouths. Some plants cause mild stomach upset; others can trigger life-threatening heart, kidney, or neurologic toxicosis. Exact risk depends on the species, plant part, and amount chewed. When identification is unclear, call a veterinarian or poison hotline with a photo. Related: sago palm toxicity, herbs toxic to dogs, and for cat households plants toxic to cats.
Key takeaways
- High-concern examples include sago palm, oleander, yew, some lilies (more catastrophic for cats), castor bean, and certain bulb plants.
- Milder but common upsets come from philodendron, pothos, and other calcium-oxalate houseplants (drooling, mouth pain, vomiting).
- Do not induce vomiting unless directed for that plant.
- Bring a sample or clear photos. Common names are unreliable.
- Pesticides and fertilizers on plants can be as dangerous as the plant itself.
Plants frequently involved in dog calls
- Sago palm / cycads: Liver failure risk. All parts toxic; seeds especially dangerous.
- Oleander and foxglove: Cardiac glycoside concerns.
- Yew: Sudden cardiac toxicosis themes.
- Autumn crocus: Severe GI and multi-organ concerns.
- Castor bean: Ricin-containing seeds; serious.
- Tulip and narcissus bulbs: GI upset; larger ingestions more concerning.
- Azalea / rhododendron: GI and cardiovascular signs possible.
- Grape vines: Grapes/raisins are the bigger documented problem; still keep dogs from raiding fruit.
This list is incomplete. Check ASPCA’s toxic plant resources for look-ups.
Signs after plant chewing
- Drooling, pawing at the mouth, vomiting, diarrhea
- Lethargy or abdominal pain
- Abnormal heart rate, collapse, or tremors (emergency)
- Jaundice or ongoing vomiting days after sago exposure (emergency)
What to do
- Remove plant access and wipe material from the mouth if safe.
- Note time and estimate amount.
- Call your veterinarian, emergency clinic, or poison hotline (ASPCA APCC 888-426-4435; Pet Poison Helpline 855-764-7661).
- Follow instructions. Do not give home antidotes from social media.
Prevention
- Choose pet-safer décor plants and hang tempting greenery out of reach.
- Identify landscaping before bringing a new dog home.
- Block compost and mulch that may hide toxic seeds or mushrooms.
FAQ
Is a nibble of pothos an ER visit?
Often causes irritation; still call for triage, especially if drooling or vomiting continues.
Are “non-toxic” lists perfect?
They help, but fertilizers, moldy water in pots, and mislabeled plants still cause problems.
