My dog ate Common Rhododendron — what to do
Step by step
- Take common rhododendron away and remove any plant material from your dog's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet, or a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. Follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet — or the ASPCA Animal Poison Control Center on (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
My dog ate common rhododendron — FAQ
Is common rhododendron poisonous to dogs?
Yes — the ASPCA lists Common Rhododendron (Rhododendron ponticum) as toxic to dogs. Rhododendron ponticum is toxic to dogs, cats, horses, and humans. All parts contain grayanotoxins (andromedotoxins), which interfere with sodium channels and can cause vomiting, drooling, heart arrhythmia, hypotension, and in severe cases seizures or death. The ASPCA lists Rhododendron species as toxic to dogs and cats. Honey made from rhododendron nectar ('mad honey') is also toxic.
