Why Your Dog Might Eat Plants (And Why It Matters!)
Dogs, being the curious creatures they are, explore the world with their mouths. When a tempting green leaf is within reach, they might nibble on it out of curiosity, boredom, or even a nutritional deficiency. While some plants are harmless, others can cause anything from mild tummy upset to severe, life-threatening reactions. Knowing the difference is key to preventing a trip to the veterinarian.
Symptoms of plant poisoning in dogs can vary widely. Some dogs might just get an upset stomach, leading to vomiting or diarrhea. Others might experience more severe reactions like drooling, lethargy, difficulty breathing, or even organ damage, depending on the plant and the amount ingested.
Identifying Poisonous Indoor Plants For Dogs: Common Culprits
Many popular and beautiful houseplants can pose a risk to dogs. It’s all about recognizing them and taking simple precautions. Let’s explore some of the most common plant families that contain toxic species.
Lilies: A Pretty Danger
While not all lilies are equally toxic to dogs, several popular varieties are highly dangerous, causing kidney failure. It’s often best to err on the side of caution and avoid lilies altogether if you have a dog.
- Peace Lily (Spathiphyllum): Contains calcium oxalate crystals that can cause intense oral irritation, drooling, vomiting, and difficulty swallowing.
- Easter Lily (Lilium longiflorum): All parts of the plant are highly toxic and can lead to severe kidney failure.
- Tiger Lily (Lilium lancifolium): Similar to Easter lilies, these are extremely toxic and can cause kidney failure.
- Stargazer Lily (Lilium ‘Stargazer’): Another member of the Lilium family, highly toxic.
The Pothos and Philodendron Family: Slippery When Nibbled
These are incredibly popular for their air-purifying qualities and ease of care, making them a favorite for beginners. However, they also contain insoluble calcium oxalates, which can cause irritation.
- Golden Pothos (Epipremnum aureum): Causes oral irritation, drooling, vomiting, and difficulty swallowing.
- Heartleaf Philodendron (Philodendron hederaceum): Symptoms are similar to Pothos: burning sensation in the mouth, drooling, vomiting.
- Split-Leaf Philodendron (Monstera deliciosa): While the fruit can be edible if properly prepared for humans, the sap and leaves contain calcium oxalate crystals, causing oral irritation.
The Classic “Best Friend” of Dogs: The Sago Palm
Despite its name, the Sago Palm (Cycas revoluta) is a cycad, not a true palm. It’s extremely toxic to dogs, with even small ingestions of seeds or roots being potentially fatal.
- Sago Palm (Cycas revoluta): All parts are toxic, but the seeds (nuts) contain the highest concentration of cycasin, which can cause liver failure, vomiting, diarrhea, seizures, and death.
The Snake Plant: Tough Exterior, Toxic Interior
Known for its resilience and striking appearance, the Snake Plant (Sansevieria trifasciata, now reclassified as Dracaena trifasciata) is a common sight in many homes. It contains saponins, which can cause gastrointestinal upset.
- Snake Plant (Sansevieria trifasciata/Dracaena trifasciata): Ingestion can lead to nausea, vomiting, and diarrhea. Luckily, it’s not typically fatal, but it’s still best to keep it out of reach.
The Colorful Schefflera (Umbrella Tree)
With its umbrella-like clusters of glossy leaves, the Schefflera (Schefflera actinophylla) is a striking addition to any indoor space. However, it also contains calcium oxalate crystals.
- Schefflera (Umbrella Tree): Chewing on the leaves or stems can cause irritation to the mouth and digestive tract, leading to symptoms like drooling, vomiting, and pain.
Azaleas and Rhododendrons: Beautiful Blooms, Dangerous Bites
These flowering shrubs are stunners, but their beauty comes with a significant risk. They contain grayanotoxins, which can affect the cardiovascular and nervous systems.
- Azaleas (Rhododendron spp.): Ingestion can cause vomiting, diarrhea, drooling, weakness, depression of the central nervous system, and in severe cases, coma or cardiovascular collapse.
- Rhododendrons (Rhododendron spp.): Share the same toxic compounds and can cause similar, severe symptoms.
Classic Houseplants and Their Dangers
Some other common houseplants that require caution include:
- Dieffenbachia (Dumb Cane): Also contains insoluble calcium oxalate crystals, causing severe oral irritation, swelling, drooling, and difficulty breathing if the swelling is severe.
- Aloe Vera: The gel inside is beneficial, but the outer leaf contains saponins and anthraquinones that are toxic, causing vomiting, lethargy, and diarrhea.
- ZZ Plant (Zamioculcas zamiifolia): Contains insoluble calcium oxalate crystals, causing oral irritation and gastrointestinal upset.
- Kalanchoe: A succulent that contains bufadienolides, cardiotoxic compounds that can cause vomiting, diarrhea, and in rare cases, heart rhythm abnormalities.
When “Poisonous” Isn’t Entirely Accurate: Understanding Severity
It’s important to note that not all plants are equally dangerous. The ASPCA Animal Poison Control Center categorizes plants based on their toxicity. Some plants cause mild, temporary irritation, while others can be fatal.
For instance, a Pothos might cause a dog to drool excessively and vomit for a few hours, leading to discomfort. On the other hand, a Sago Palm can cause severe liver damage and potentially death, requiring immediate emergency veterinary care. Always consult reliable resources like the ASPCA’s toxic and non-toxic plant list for comprehensive information.

How to Keep Your Dog Safe Around Indoor Plants
Don’t despair! Having a dog doesn’t mean you have to give up your green thumb. With a little planning and knowledge, you can enjoy a home filled with plants safely.
1. Research Before You Buy
This is the most crucial step! Before bringing any new plant home, do a quick search to ensure it’s safe for your pets. Websites like the ASPCA have extensive databases that can help. Consider this a vital part of your plant selection process, just like checking for sunlight needs or watering schedules.
2. Educate Yourself on Common Houseplants
Familiarize yourself with the plants that are most commonly found in homes and known to be toxic. This includes the ones we’ve discussed: lilies, pothos, philodendrons, sago palms, etc. Knowing the usual suspects means you can be extra vigilant.
3. Strategic Plant Placement
If you have a plant that isn’t ideal for your dog’s current level of interest but you want to keep it, placement is everything!
- High Shelves: Place plants on shelves that are far too high for your dog to reach. Make sure these shelves are stable and unlikely to be knocked over.
- Hanging Baskets: Suspend plants from the ceiling or wall brackets. Ensure they hang far enough away from any furniture your dog might use as a stepping stone.
- Dedicated Plant Room: If possible, keep plants in a room your dog doesn’t have access to at all times, or create a designated “plant oasis” where they are kept safely behind a barrier your dog can’t cross.
- Terrariums: Glass enclosures can beautifully display certain plants and completely block pet access.
4. Training and Supervision
Train your dog to avoid chewing on plants. This takes consistency and positive reinforcement. Reward them for ignoring plants or for engaging with their own toys instead. Always supervise your dog when they are in areas with plants, especially when they are young or new to the environment.
5. Provide Alternatives for Chewing
Ensure your dog has plenty of appropriate chew toys. Sometimes, dogs chew plants out of boredom or a need to satisfy their chewing instinct. Offering safe, engaging chew toys can redirect this behavior. Rotate toys to keep things interesting.
6. What to Do if Your Dog Ingests a Potentially Toxic Plant
If you suspect your dog has eaten a toxic plant, don’t wait! Act quickly.
- Identify the Plant: If possible, take a sample of the plant with you or a clear photo to show the vet.
- Observe Your Dog: Note any symptoms your dog is experiencing, such as vomiting, diarrhea, lethargy, drooling, or unusual behavior.
- Contact Your Veterinarian Immediately: Call your vet or an emergency animal hospital. If you can’t reach them, contact an animal poison control center, like the ASPCA Animal Poison Control Center at (888) 426-4435 (note: a consultation fee may apply).
- Do NOT Induce Vomiting Unless Advised: Some substances are more harmful coming back up. Always follow the advice of a veterinary professional.
