Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, and depression.
Escalation note
Symptoms are generally limited to the digestive tract. Consult a veterinarian if you suspect your dog has ingested the plant to ensure proper monitoring.
First aid at home
Per Pet Poison Helpline, get the dog away from the plant and gently wipe plant material from in and around the mouth with a damp cloth. Do not induce vomiting unless your veterinarian specifically tells you to.
What to watch for
Vomiting and diarrhea come first, often with lethargy or a 'depressed' demeanor. Bigger ingestions, especially of bark or roots where paeonol concentrates, can produce more substantial GI upset.
Time window
Signs typically begin within hours of ingestion and resolve in 24-48 hours with supportive care; ASPCA does not document precise timing.
When to call the vet
Call your vet if symptoms last more than a few hours, your dog can't keep water down, or seems weak, painful, or unusually flat. A same-day appointment is normally appropriate; ER care is rarely necessary.
What this means for your dog
Dogs that munch peony leaves, flowers, or bark are most likely to end up with a stomachache rather than a poisoning crisis. ASPCA lists the toxic principle as paeonol and the clinical signs as vomiting, diarrhea, and depression — severity is typically mild to moderate.
