THE Most Toxic Plant to Your Dog

water-hemlock-dogs

It may look soft, delicate and even docile, but this wildflower is one of the most toxic – and fast acting – plants your dog can ingest (even in a small amount).

(It’s also highly poisonous to humans.)

It’s called Water Hemlock and is a member of the carrot family. It typically grows in wet areas like marshes and swamps, damp pastures and along riverbanks, ponds, streams, irrigation ditches, reservoirs and other water edges in both North America and parts of Europe.

Water hemlock is also known as:

  • beaver poison
  • poison parsley
  • muskrat weed
  • poison parsnip
  • spotted water hemlock
  • western water hemlock
  • cowbane/spotted cowbane
  • bulblet-bearing water hemlock

If ingested, the violent effects of toxic poisoning may become evident within a few minutes (from a toxin called cicutoxin, an aggressive, poisonous stimulant that attacks the nervous system) and include:

  • Drooling
  • Nervousness/agitation/weakness
  • Dilated pupils
  • Seizures and/or twitching
  • Rapid heart rate/difficulty breathing/asphyxiation/choking
  • Coma
  • Death from respiratory paralysis death (occurring between 15 minutes and 2 hours after the first initial signs of poisoning).

While the highest levels of its toxin is found in the roots, all parts of the water hemlock are poisonous and dog lovers should never let their dog get anywhere near it.

A side note, the water hemlock has a strong carrot-like odor which could attract curious dogs.

If you suspect your dog has come into contact with water hemlock, seek immediate emergency veterinary care.

    • Interesting question … here’s some additional info, hope this helps!

      Water hemlock bears a close resemblance to other members in the family Apiaceae and may be confused with a number of other edible and poisonous plants.

      The Apiaceae family (or Umbelliferae), commonly known as the celery, carrot or parsley family, are a family of mostly aromatic plants with hollow stems. The family, which is named after the type genus Apium, is large, with more than 3,700 species spread across 434 genera; it is the 16th-largest family of flowering plants.[1] Included in this family are the well-known plants: angelica, anise, arracacha, asafoetida, caraway, carrot, celery, Centella asiatica, chervil, cicely, coriander (cilantro), culantro, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, cow parsnip, sea holly, giant hogweed and silphium (a plant whose identity is unclear and which may be extinct).

      The common name hemlock may also be confused with poison hemlock (Conium maculatum).
