Why it matters

A low, sprawling native yew of northeastern woodlands that can grow along wooded pasture edges. Check fence lines before turning alpacas into new woodland paddocks.

Signs of Canada yew poisoning in alpacas

  • Sudden death (often the first sign)
  • Slow, irregular or very fast heartbeat
  • Weakness, trembling, collapse
  • Diarrhea and colic
  • Cold extremities

Signs can appear within minutes (cyanide, cardiac toxins) or only after weeks of exposure (liver toxins). Many poisoned camelids are simply found dead, so prevention is everything.

What to do if your alpaca ate Canada yew

  1. Move the herd away and remove any remaining plant material, clippings or fallen leaves.
  2. Call your veterinarian immediately, even if the alpaca looks normal. Say what was eaten, roughly how much and when.
  3. Bring a sample or clear photo of the plant to help identification.
  4. Do not give home remedies, oils or try to make the alpaca vomit unless your vet tells you to.
  5. Keep the animal quiet, in shade or shelter, with water available. Write down the time and every symptom you see.
  6. Check every other alpaca that had access, then remove the plant permanently (including roots).

Emergency: call your veterinarian immediately. If you cannot reach them, contact an animal poison control service (in the U.S., the ASPCA Animal Poison Control Center or Pet Poison Helpline; fees may apply). Bring a sample or photo of the plant.
