Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, and abdominal pain.
Escalation note
Consumption of the berries or foliage may cause gastrointestinal irritation; please consult a veterinarian for professional guidance if ingestion occurs.
What to watch for
Vomiting and diarrhea are the most common signs in dogs. Weakness can develop with larger doses. Seizures are rare but possible and indicate a serious exposure that needs emergency care.
Time window
Pet Poison Helpline notes that mild GI cases are often manageable but doesn't give a precise onset window — exact timing not well documented. Plan on watching for 24–48 hours after any suspected ingestion.
When to call the vet
Call your vet or ASPCA Poison Control (888-426-4435) if your dog vomits, has diarrhea, or seems weak — and call immediately if seizures, repeated vomiting, or known berry ingestion. Pet Poison Helpline (855-764-7661) is a paid alternative.
What this means for your dog
Dogs that chew American Bittersweet — especially the showy red berries — can get sick. ASPCA lists vomiting, diarrhea, weakness, and rarely seizures, and Pet Poison Helpline notes the berries are the most concentrated part of the plant.
