Question

If a horse eats some yew tree will it kill them

Answer 1

I would keep a very close eye on it for the next few hours.

A large dose of Yew Tree would be very bad but the odd bit might not do too much harm..

You need to ensure that it doesn't get colic.  Any signs of distress, sweating, looking at or biting its stomach get the Vet asap and keep it walking about.

If at all unsure call the Vet- better safe than sorry.
