Can Dogs Eat Mushrooms?
Caution — store-bought only
Plain, store-bought mushrooms are safe for dogs in small cooked amounts — button, cremini and portobello are all non-toxic. Wild mushrooms are a different story entirely: several species are deadly to dogs, identification is unreliable even for experts, and ingestion should be treated as an emergency.
The details: why this verdict
Shop mushrooms (button, cremini, portobello, shiitake) are non-toxic to dogs. The real kitchen risk is what they’re cooked with — butter, garlic, onion and heavy seasoning don’t belong in a dog’s bowl; garlic and onions are toxic in their own right.
Wild mushrooms are where dogs get into serious trouble. Species like Amanita phalloides (death cap), Galerina and Inocybe can cause liver failure, neurological signs or death, and symptoms are often delayed by hours — by the time a dog looks sick, damage is under way. If your dog eats any wild mushroom, don’t wait to identify it: go to a vet immediately and bring a photo or sample of the mushroom. Our emergency hub lists poison hotlines for your country.
How much is okay?
A few small pieces of plain, cooked store-bought mushroom occasionally is fine. Skip raw mushrooms (harder to digest) and anything cooked in butter, oil, garlic or sauces. Wild mushrooms: zero — always an emergency.
Symptoms to watch for
- Vomiting or diarrhea (may be delayed several hours after wild mushrooms)
- Drooling or excessive tearing
- Weakness, wobbliness or lethargy
- Yellowing gums or eyes (jaundice — liver involvement)
- Tremors or seizures
- Collapse — go to an emergency vet immediately
