Mushroom Poisoning in Dogs and Cats

Why Mushrooms Are Toxic

Mushrooms contain toxins that can cause severe illness or death in pets.

Some mushrooms are more toxic than others, and even small amounts can be harmful.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Symptoms of mushroom-poisoning poisoning

• Vomiting and diarrhea within 2-6 hours after ingestion.
• Lethargy or weakness.
• Loss of appetite.
• Severe abdominal pain.
• Jaundice or yellowing of the gums and eyes.

What to do right now

1. Call your vet or a poison line immediately.
2. Do not induce vomiting unless directed by a vet.
3. Bring any mushrooms your pet has eaten to the vet.
4. Monitor for signs of poisoning and seek veterinary care if necessary.
