Common Name: Rhododendron
Scientific Name: Rhododendron spp (Ericaceae)

Rhododendrons are commonly found in the Northern hemisphere and are popular plants for landscaping. All parts of the plant are considered toxic. It is important to keep these plants out of pet areas. Always clean up clippings before a pet has access to them.

Signs and symptoms of toxicity: Clinical signs of toxicity may be seen within an hour of ingestion but could take up to 12 hours to develop. The most common signs of toxicity include vomiting, diarrhea, abdominal pain, and refusal to eat. Other signs may include changes in heart rate, decreased blood pressure, weakness, tremors, seizures, paralysis, blurred vision, trouble breathing, and vocalization.

Toxic consumption: The minimum threshold for toxicity is not known and suspected consumption should be reported immediately.
