Is Bog rosemary toxic to dogs?

Yes — bog rosemary is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. Andromeda polifolia contains grayanotoxins (andromedotoxins), toxic to dogs, cats, horses, and humans. All parts are poisonous; ingestion causes nausea, vomiting, low blood pressure, muscle weakness, and potentially life-threatening cardiac arrhythmia. Keep away from pets and children. The common name 'rosemary' is misleading — it is unrelated to culinary rosemary.

Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to bog rosemary.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
