Is Oleander Toxic to Dogs?
Emergency🚨 Dangerous — act now
Oleander's cardiac glycosides act like an uncontrolled overdose of heart medication: a few leaves can kill a dog, and even dried clippings or water from a vase remain toxic. It's everywhere in warm-climate landscaping, which makes it one of the most dangerous 'ordinary' plants a dog encounters. Speed of treatment decides outcomes.
What makes it dangerous: Cardiac glycosides (oleandrin)
Symptoms to watch for
- Drooling, vomiting (possibly bloody)
- Weakness
- Slow, fast, or irregular heartbeat
- Tremors, collapse, seizures
What to do right now
- Emergency — vet or hotline immediately, even for a suspected nibble
- Do not induce vomiting on your own
- Fence off or remove oleander from dog areas permanently
