Can Dogs Eat Mushrooms?
Some mushrooms are safe for dogs, but many others — especially wild mushrooms — can be extremely dangerous. Supermarket varieties like button, chestnut, and portobello mushrooms are usually safe when cooked plainly. But wild mushrooms can contain toxins that affect the liver, kidneys, and nervous system.
The main rule is simple: never allow your dog to eat mushrooms in the wild, and only serve store-bought mushrooms that are cooked and unseasoned.
