TailVilleWhy
Store-bought culinary mushrooms like button, shiitake, oyster and enoki are not known to be toxic to pets. They aren't easy to digest, though, so raw or large servings can upset the stomach, and thin, chewy enoki can catch in the throat. Mushroom dishes usually include garlic, onion, butter or soy sauce. Wild mushrooms are extremely risky because toxic and edible species are hard to tell apart.
How to give it / if eaten
Cook store-bought mushrooms plain and chop them finely. About a teaspoon for cats and small dogs and a tablespoon for large dogs is plenty. Start small and check the stool. If your pet eats a wild mushroom on a walk, call your vet immediately.
Watch for these signs
Too much may cause vomiting, diarrhea or gas. After a wild mushroom, depending on the species: vomiting, diarrhea, drooling, wobbliness, seizures, or liver damage days later.
