🩺 Mushroom Poisoning in Dogs – Vet‑Led Guide 2025 🍄🐶

By Dr. Duncan Houston BVSc

Hello, I’m Dr Duncan Houston, BVSc, founder of Ask A Vet. Wild mushroom ingestion can be life-threatening. This deep-dive guide covers toxin types, early signs, emergency steps, treatment, recovery, and prevention. With prompt action and proper care, most dogs can recover. Let’s keep our curious pups safe and thriving. 🐾

⚠️ Why Mushrooms Can Be Dangerous

In the U.S., fewer than 100 of the 10,000 mushroom species are toxic—but “death caps” among them can be fatal. Toxins like amanitins (liver), orellanine (kidney), gyromitrin, muscarine, and neurotoxins cause varying effects .

⏱ Timeline of Symptoms

• 15–120 min: vomiting, diarrhea, drooling.
• Up to 24 hrs: tremors, colic, staggering, dehydration.
• 1–3 days: liver or kidney failure—jaundice, seizures, low urine, coma.

🚩 Key Clinical Signs

• Vomiting, diarrhea, abdominal pain, and excessive drooling .
• Lethargy, weakness, disorientation, and stumbling.
• Neurologic signs—tremors, seizures, collapse.
• Jaundice: yellow gums/eyes (liver damage).
• Changes in urination, increased thirst (kidney involvement).

🔬 Diagnosing Mushroom Poisoning

1. History + bring a mushroom sample/photo.
2. Physical exam, bloodwork, urinalysis.
3. Liver/kidney function tests and electrolytes.
4. Clotting profiles for liver toxins.
5. Special tests for amatoxins or orellanine if available .

🚨 Emergency & Veterinary Treatment

1. Immediate First Aid

• Remove mushrooms from your mouth.
• Collect a sample in a sealed bag.
• Seek immediate vet care—don’t wait for symptoms.

2. Early Veterinary Measures

• Induce vomiting + repeat activated charcoal if <2 hrs ingestion.
• Administer IV fluids to maintain circulation.
• Electrolyte & acid-base correction.
• Vitamins/milks thistle (silibinin), penicillin G to reduce liver uptake of amatoxins .
• Monitor for hyperviscosity, coagulopathy, and glucose swings.
• Treat symptoms: anti-nausea, anticonvulsants, pain relief.
• Advanced support: dialysis, plasmapheresis, blood transfusion when needed .
• Liver transplant if indicated (rare cases) .

3. Recovery & Aftercare

• Continue hospitalization for 3–5+ days with monitoring.
• Repeat labs to track liver & kidney recovery.
• Gradually reintroduce bland diet.
• Watch for late complications like GI ulcers, renal damage.

📅 Prognosis

• Early, aggressive treatment increases survival dramatically.
• Amanita toxicity fatality rate is 50–90% without care, but recovery is possible with support .
• Milder toxins are often self-limiting with supportive care.
• Survivors may fully recover or need continued organ support.

🏡 Prevention & Safety Tips

• Assume all wild mushrooms are toxic; remove them from the yard promptly.
• Train the “leave it” command for outdoor safety .
• Supervise while hiking—stay on trails, avoid damp wooded areas.
• Inform guests to clean up after picnicking.
• Know your local dangerous species (Amanita, Galerina, Lepiota, Gyromitra, Orellanus) .
