Read the full first-aid guide: what to do if your pet ate something toxic
Azalea risk in the US looks different depending on which coast you're on. In the Southeast, azalea is a foundation shrub - Clemson HGIC calls it among the most popular flowering shrubs grown in South Carolina, planted right along the front of the house where a dog let into the yard can graze on fallen blooms or low branches. In the Pacific Northwest, the same risk shows up under the name rhododendron: Washington State University Extension covers azalea and rhododendron together as popular regional landscape plants.
Either plant, either coast, the danger is the same molecule. ASPCA lists azalea and rhododendron as severely toxic to dogs and cats: grayanotoxins interfere with normal heart, muscle and nerve function, causing vomiting, diarrhea, drooling, weakness and potentially cardiac failure. Because the toxin is cardiac, do not induce vomiting at home - call ASPCA Animal Poison Control (888-426-4435) or Pet Poison Helpline (855-764-7661) first, especially if your dog has ongoing access to azalea or rhododendron growing on your own property.
