Call a vet now

Call your vet or the nearest emergency vet right now. Some mushroom toxins will affect pets very rapidly (within 15-30 minutes of ingestion), while others may not produce signs for many hours (up to 24 hours).

What to do right now

  1. Call your vet or the nearest emergency vet.
  2. Note what was eaten, how much and when.
  3. Bring the packaging.
  4. Keep your pet calm.
  5. Remove what is left.

Don't

  • Do not make your pet vomit unless a vet tells you to.
  • Do not give any human medicine.

Why it can be dangerous

Only a small percentage of mushrooms is considered toxic.[1] Accurate mushroom identification is difficult and should be left to experts (mycologists).[1]
