The Short Answer
Store-bought edible mushrooms are mostly fine. Wild mushrooms can kill a dog.
Why Mushrooms Needs Caution
Common grocery store mushrooms (cremini, white, portobello) are safe. Wild mushrooms vary from harmless to fatal — and dogs cannot tell the difference.
Some species like Amanita phalloides cause liver failure in 24-48 hours. Inocybe and Clitocybe species cause neurological symptoms within an hour. Identification by sight is unreliable even for experts.
How Much Is Actually Safe?
Plain cooked store-bought mushrooms in tiny amounts are fine. Never anything wild. Skip if cooked with onion, garlic, or butter (which is everything in a normal kitchen).
Symptoms to Watch For
- Vomiting
- Diarrhea
- Severe abdominal pain
- Jaundice (yellowing of gums)
- Seizures
- Drooling
- Coma
When to Call the Vet
Any wild mushroom ingestion is an emergency. Even if your dog seems fine for hours, liver damage from Amanita is delayed and progressive. Bring a sample of the mushroom to the vet.
