Safety status
What this means for your dog
Dogs are the species most commonly poisoned by yesterday-today-and-tomorrow — an ASPCA APCC review found 38 cases involving 42 dogs over five years, with no exposures recorded in other species. The plant's brunfelsamidine and related alkaloids cause severe, potentially fatal neurological signs, and seeds and seed pods are the most concentrated source.
What to watch for
Early signs are agitation, nervousness, or excitement followed by hypersalivation, vomiting, and diarrhea. Neurological signs progress to muscle tremors, shaking, muscular rigidity, paddling, incoordination, and tonic-clonic seizures that can recur for several days. Coughing and lethargy are also reported.
Time window
Clinical signs typically begin within 2 hours of exposure, sometimes longer, and can progress over hours to days. Seizures may continue for several days and require inpatient management.
When to call the vet
Call immediately. Any suspected ingestion is an emergency, and any tremor, twitching, or seizure is a reason to drive to the ER vet right now. Phone the ASPCA APCC (888-426-4435) or Pet Poison Helpline (855-764-7661) on the way.
First aid at home
Bring any chewed plant material, seeds, or seed pods (or a clear photo) to the clinic so the team can confirm Brunfelsia. Do not induce vomiting at home, especially if your dog is tremoring or seizing — call ASPCA APCC (888-426-4435) or Pet Poison Helpline (855-764-7661) and follow their instructions while you transport.
