# Is Yew Poisonous to Dogs and Cats?

Published by Paw Multiverse (A.I.T. Multiverse Consulting Ltd) · Last updated 7 November 2026

Quick answer

Yes, seriously. The ASPCA lists yew (Taxus species, including Japanese yew) as toxic to dogs, cats and horses. It names taxine as the toxin and lists sudden death from acute heart failure, with early signs in dogs of muscle tremors, difficulty breathing and seizures. Treat any yew eating as an emergency.

## What the ASPCA says

The ASPCA lists yew (Taxus spp., also called Japanese yew) as toxic to dogs, cats and horses, with taxine as the toxic principle. Yew is a common evergreen hedge and is cut for winter wreaths and garlands.

## Symptoms

The ASPCA lists sudden death from acute cardiac failure, and early signs of muscle tremors, dyspnoea (difficulty breathing) and seizures in dogs. Because the first sign can be collapse, do not wait for symptoms. Source: [ASPCA Animal Poison Control, Yew](https://www.aspca.org/pet-care/animal-poison-control/toxic-and-non-toxic-plants/yew).

## What to do now

- Phone your vet or the nearest emergency vet and go in straight away, even if your pet seems well.
- Take a sprig of the plant or a photo so the vet can confirm it is yew.
- Do not give food, drink or remedies to make your pet sick unless a vet tells you to.

## Prevention

- Do not use yew cuttings in wreaths or table decorations in a home with pets.
- Clear up hedge clippings straight away, and keep dogs away from yew hedges they chew.
