Hemlock

[Sharon]

Recommend you not use hemlock mulch nor let your dog chew on hemlock . My friend almost lost his dog this week, due to hemlock mulch.

Sharon, Do you mean the tree hemlock (Genus Tsuga) not the forb hemlock (Genus Cicuta). The forb is extremely poisonous and would kill a dog quickly if they ingested even a tiny bit.

I don't know. I'll do some more research.

edit:

Some links say the tree can cause more minor problems - as you say.

The following trees are commonly known to contain seizure-causing toxins for dogs:

- Wild cherries (twigs and leaves especially toxic; contain a compound that releases cyanide)
- Oak (foliage and acorns toxic; effects accumulate gradually)
- Black locust (bark and shoots toxic)
- Buckeye (sprouts, nuts and seeds toxic)
- Elderberry (leaves, bark and roots toxic)
- Yew (bark, leaves and seeds toxic)
