Safety status
What this means for your dog
Dogs — azaleas and rhododendrons are toxic, and the dose that makes a dog sick is small. Grayanotoxins in the leaves and flowers disrupt heart and skeletal muscle sodium channels; ASPCA-cited dose data put the threshold at roughly 0.2% of body weight, so a 30-lb dog can show signs after eating less than an ounce of plant material.
What to watch for
Excessive drooling and vomiting almost always come first, often with diarrhea and loss of appetite. Watch for weakness, wobbling, or tremors, and for cardiac signs — slow or irregular heart rate, pale gums, or labored breathing. Severe cases progress to seizures, hypotension, and cardiovascular collapse.
Time window
Signs usually appear within a few hours of ingestion. With aggressive supportive care most dogs recover over 24–72 hours; severe cardiac cases can take longer and, untreated, can be fatal.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) immediately if you saw chewing, even before symptoms appear — grayanotoxin poisoning is dose-dependent and earlier treatment matters. Also call right away for any vomiting that won't stop, weakness or collapse, or change in heart rate or breathing.
First aid at home
Remove any plant material still in the dog's mouth and bag a sample of leaves or flowers to bring with you. Do not give hydrogen peroxide or anything else to induce vomiting unless your vet or ASPCA APCC tells you to — call first.
