Wat Nu Te Doen
- 1
THIS IS A TRUE EMERGENCY
Do NOT wait for symptoms. Amatoxin poisoning has a deceptive delay — your dog looks fine for 6-24 hours while the toxin destroys the liver. Call ASPCA Poison Control at (888) 426-4435 NOW.

Collect a Mushroom Sample
If safe, collect remaining mushroom pieces (including base/bulb). Place in a paper bag (not plastic). This helps mycologists identify the species and determine toxicity risk.
- 3
Go to Emergency Vet for Decontamination
Your vet will induce vomiting (if within 2 hours), administer activated charcoal, and start IV fluids. They will monitor liver enzymes for 48-72 hours. Early treatment is the ONLY effective defense.

Prepare for Hospitalization
If amatoxin poisoning is confirmed, treatment includes: Penicillin G, Silymarin (milk thistle), N-acetylcysteine, IV fluids, and potentially plasma transfusions. Hospitalization typically lasts 3-7 days.
De Wetenschap Erachter
Amatoxines (alpha-amanitine, beta-amanitine) zijn bicyclische octapeptiden gevonden in Amanita, Galerina en Lepiota soorten. Ze remmen RNA polymerase II, wat de eiwitsynthese in hepatocyten gestopt wordt. De lever is het primaire doelwit omdat amatoxines enterohepatische recirculatie ondergaan. Na inname is er een 6-12 uur latente periode, gevolgd door een gastroenteritis-fase, een kortstondig vals herstel (12-24 uur), dan fulminant leverfalen met coagulopathie, encefalopathie en overlijden. Behandeling binnen 12 uur heeft een 90% overlevingskans; na 24 uur daalt de overleving tot 30% (ASPCA, 2023).
Giftige Dosis Berekenaar
Gegeten Hoeveelheid: 0,1 mg/kg amatoxine (één Death Cap = 10-15mg)
LD50: Niet goed vastgesteld; 0,1mg/kg amatoxine potentieel fataal
De Wetenschap Erachter: ASPCA Animal Poison Control Center, 2023
Eén enkele Amanita phalloides hoed bevat genoeg amatoxine om een 10-20kg hond te doden. Gedeeltelijke inname is nog steeds levensbedreigend.
Symptomentijdlijn: Wat U Kunt Verwachten
Latent phase: dog appears normal. Toxin is being absorbed.
Gastroenteritis phase: explosive vomiting and diarrhea begin. This is the BEST treatment window.
False recovery: symptoms temporarily improve. Owners think dog is healing — FALSE sense of security.
Fulminant liver failure: jaundice, bleeding disorders, hepatic encephalopathy, death without aggressive treatment.
Veelgestelde Vragen
Are wild mushrooms toxic to dogs?
Many wild mushroom species are extremely toxic to dogs. The most dangerous is Amanita phalloides (Death Cap), which contains amatoxins that cause irreversible liver failure. Other toxic genera include Galerina, Lepiota, and Cortinarius. Even non-lethal species can cause severe GI upset. ANY mushroom ingestion should be treated as an emergency because you cannot reliably identify species in the field.
How long after eating a mushroom will my dog show symptoms?
Symptoms from amatoxin-containing mushrooms (Amanita) are DELAYED 6-24 hours. A dog appears fine initially, then develops explosive vomiting and diarrhea. After a brief "false recovery" of 12-24 hours, liver failure begins. By the time jaundice appears, damage is often irreversible. Other species cause symptoms within 30 minutes to 6 hours.
What should I do if my dog ate a wild mushroom?
Treat EVERY wild mushroom ingestion as a life-threatening emergency. Call ASPCA Poison Control at (888) 426-4435 immediately. Your vet will induce vomiting (if within 2 hours), administer activated charcoal, and admit for 48-72 hour observation with liver enzyme monitoring. Do NOT wait for symptoms — early treatment is the only effective defense against amatoxin poisoning.
Can a dog die from eating a mushroom?
Yes. Amanita phalloides (Death Cap) has a 50-100% mortality rate in dogs without treatment. Amatoxins destroy liver cells by inhibiting RNA polymerase II. Even with treatment, mortality remains 20-30%. The lethal dose is 0.1mg/kg of amatoxin — a single Death Cap cap contains 10-15mg. Early aggressive treatment (within 12 hours) significantly improves survival.
Can dogs eat store-bought mushrooms?
Store-bought mushrooms (white button, cremini, portobello) are generally safe for dogs in small amounts. However, they offer little nutritional value and can cause GI upset if fed in large quantities or cooked with butter/oil/garlic. Never assume a field mushroom is safe — only eat mushrooms you purchased from a grocery store.
