I know that Yew is very poisonous, and that one of the most poisonous parts of the plant is the hard green seed in the middle of the berries. I also know that the berries themselves (minus the seed) are not poisonous and that the seed can pass through undigested (and therefore without causing illness) provided that it is not broken.
There are masses of berries coming down from a Yew in my garden, which I'm removing as much as is practical. A month ago I saw my puppy eat one, before I became so sensitive to the issue. I spoke to the vet about it and we kept an eye on him and all was well. It is possible that he has eaten them on more than one occasion without me noticing.
I have now become much more sensitive about it, and am afraid to let him in the garden at all without monitoring this really closely. However, I have lived 20 years in this house, with this tree, and with dogs, without anything bad happening -- and without even being aware of the problem until recently.
My question is: How worried are other dog owners about Yew poisoning? Is there anyone reading this who has a dog and a yew tree? How concerned/cautious are you about it?
Many thanks.
