Why it matters

Also called lambkill — the name says it all.

Signs of sheep laurel poisoning in alpacas

  • Green, foamy regurgitation or drooling
  • Repeated attempts to vomit (unusual in camelids)
  • Colic, teeth grinding
  • Weakness, staggering, lying down
  • Slow heart rate, low blood pressure
  • Death in severe cases

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 sheep laurel

  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.

Keeping pastures safe

  • Walk every paddock and fence line each season and remove toxic plants, including roots.
  • Never throw garden, hedge or lawn clippings over the fence.
  • Check pastures after storms for fallen branches (cherry, red maple).
  • Buy hay from known sources and inspect it for weeds.
  • Keep pastures well managed — hungry alpacas eat plants they would normally avoid.
