Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, lethargy, muscle tremors, seizures, difficulty breathing, and irregular heartbeat.
Escalation note
The toxins in this plant are potent and can be fatal even in small amounts. Immediate veterinary intervention is required if your dog has chewed or ingested any part of the plant.
First aid at home
Per Pet Poison Helpline: remove your dog from the plant, confirm it is breathing and acting normally, do NOT give home antidotes, and do NOT induce vomiting unless a vet or poison control instructs you to. Bring a sample of the plant material with you to the clinic.
What to watch for
In dogs, the most common early signs are muscular tremors, difficulty breathing, drooling, and vomiting. Pet Poison Helpline also reports weakness, dilated pupils, an initially fast then slowed heart rate, low blood pressure, seizures, coma, and sudden death. Sudden collapse can precede the milder signs.
Time window
Pet Poison Helpline reports that yew toxicity can develop rapidly after ingestion, with sudden cardiac death possible. Specific onset and recovery windows for dogs are not well documented in the cited sources.
When to call the vet
Call immediately, before symptoms appear. Any quantity of yew chewed by a dog warrants an emergency vet visit or a call to ASPCA Poison Control / Pet Poison Helpline.
What this means for your dog
Dogs: yew is acutely lethal. Chewed needles or bark can trigger fatal cardiac arrest, and the ASPCA flags muscular tremors, dyspnea, and seizures as early warning signs in dogs. Treat any yew ingestion as a true emergency, not a wait-and-see GI upset.
