Can Dogs Eat Mushrooms?
Store-bought mushrooms are safe. Wild mushrooms can be deadly — if your dog ate a wild mushroom, call your vet immediately.
Store-bought = safe. Wild mushrooms = dangerous.
Plain, store-bought mushrooms (white button, cremini, portobello, shiitake) cooked without seasoning are safe for dogs. However, wild mushrooms growing in your yard or on walks can be extremely toxic — some species can cause liver failure, seizures, and death within hours. If your dog eats a wild mushroom, treat it as a veterinary emergency.
