Yes — yew is severely toxic to dogs. The needles, bark and seeds carry taxine alkaloids that can stop the heart, and deaths are well documented.

Also known as: English Yew, Japanese Yew, Taxus baccata · Taxus baccata

What makes it toxic

Taxine A and B alkaloids, concentrated in needles and seeds, which slow cardiac conduction and cause potentially fatal arrhythmias.

Warning signs to watch for

Trembling, incoordination, difficulty breathing, slow heart rate, dilated pupils, vomiting and collapse, sometimes within hours and sometimes suddenly.

What to do if your dog eats it

Drop-everything emergency. Go straight to a veterinary ER with a sample of what was chewed. Early decontamination and cardiac support save lives; waiting does not.

Common questions

How much yew is lethal to a dog?

A mouthful or two of needles can be fatal to a small dog. This is one of the few plants where the threshold is genuinely tiny.

My dog chewed a yew branch that looked dry — is it still dangerous?

Yes. Dried clippings remain toxic for months. Storm debris, hedge trimmings and mulch all carry live taxine.

Is the ground around a yew hedge dangerous too?

Fallen needles accumulate under hedges and dogs sniff and chew them. Sweep or bag clippings and supervise dogs near yew hedges.
