Guarding Your Garden: Navigating the Hidden Dangers of Toxic Plants for Pets



I know that when we were redoing our backyard landscaping, we made some costly decisions by not first checking to see if the plants we were choosing were pet-safe. After ripping and redoing before we had an emergency, we thought to highlight here some plants that are common to landscapes in North America.


1. Azalea and Rhododendron: These plants contain grayanotoxins that can cause vomiting, diarrhea, drooling, and even more severe symptoms like heart issues or coma if ingested by dogs.


2. Sago Palm: All parts of the sago palm are highly toxic to dogs and can cause liver failure, vomiting, diarrhea, seizures, and even death if ingested.


3. Oleander: Oleander contains toxins called cardiac glycosides, which can affect the heart and cause symptoms like vomiting, diarrhea, heart problems, and even death.


4. Castor Bean Plant: The seeds of the castor bean plant contain ricin, a highly toxic substance that can cause severe gastrointestinal and neurological symptoms.


5. Lilies: Many species of lilies, including Easter lilies, tiger lilies, and daylilies, are toxic to dogs and can cause kidney failure if ingested.


6. Daffodils: All parts of the daffodil plant contain toxic alkaloids that can lead to vomiting, diarrhea, abdominal pain, and even heart arrhythmias in dogs.


7. Autumn Crocus: This plant contains colchicine, which is highly toxic and can lead to severe gastrointestinal symptoms, organ damage, and even death in dogs.


8. Yew: The yew plant contains taxine alkaloids that can cause rapid heart rate, difficulty breathing, tremors, and seizures in dogs.


9. Foxglove: Foxglove contains cardiac glycosides that can affect the heart and cause symptoms like vomiting, diarrhea, heart irregularities, and death.


10. Morning Glory: While beautiful, morning glory seeds can be toxic to dogs and cause symptoms like vomiting, diarrhea, and even hallucinations.


11. Hydrangea: Hydrangea contains cyanogenic glycosides that can lead to vomiting, diarrhea, and in some cases, lethargy and coma.


12. Japanese Yew: Similar to other yew species, Japanese yew contains toxic alkaloids that can lead to cardiac and neurological issues if ingested by dogs.


It's important to note that this list is not exhaustive, and there are many other plants that could be toxic to dogs. If you're unsure about the safety of a specific plant in your landscaping, it's a good idea to consult with a veterinarian or do thorough research before planting or allowing your dog access to the area. If you suspect your dog has ingested a toxic plant, contact your veterinarian or an emergency animal clinic immediately.
