Pet ingestion lookup
My dog ate Pacific Yew - what should I do?
Taxus brevifolia
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Muscle weakness, dilated pupils, collapse, irregular heartbeat, and gastrointestinal distress.
Escalation note
The entire plant is toxic and can be fatal if ingested. Seek immediate veterinary care if you suspect your dog has consumed any portion of this plant.
First aid at home
Remove any remaining plant from your dog's mouth, save a piece for ID, and head to the vet now. Do not induce vomiting at home — Pet Poison Helpline lists unsupervised emesis as a common first-aid mistake, and yew exposure needs cardiac monitoring.
What to watch for
Tremors, vomiting, drooling, and trouble breathing are common. Dogs are also prone to seizures with this exposure, and acute heart failure can occur suddenly — sometimes as the first visible sign.
Time window
Onset can be within hours of ingestion, but yew is notorious for sudden cardiac death without much preceding clinical illness, which is why immediate evaluation is essential even if your dog seems fine.
When to call the vet
Treat any chewing on yew foliage, bark, or berries as an emergency. Call ASPCA Poison Control (888-426-4435) or go directly to a vet — don't wait for symptoms to develop.
What this means for your dog
All parts of Pacific yew except the fleshy red aril are highly toxic to dogs, with the needles and seeds carrying the highest taxine load. The taxine alkaloids interfere with cardiac conduction, and dogs are at risk of seizures and sudden cardiac collapse on top of the GI signs.
