Can dogs eat mushrooms (store-bought)?

In moderation
Only plain, store-bought mushrooms are considered safe, and even those are best avoided.

Why

Mushrooms sold in grocery stores are generally non-toxic when served plain, but wild mushrooms can be extremely dangerous and are hard to tell apart from safe varieties. Toxic species such as Amanita contain amanitin toxins that cause severe gastrointestinal illness followed by liver and kidney failure. Because dogs gain no nutritional benefit from mushrooms, veterinarians recommend skipping them entirely and treating any wild mushroom ingestion as an emergency.

How much is safe

If offered at all, only plain, washed, store-bought mushrooms cooked without oil, butter, salt, garlic, or onions, in small amounts.

Warning signs to watch for

Vomiting, diarrhea, drooling, weakness, and with toxic wild species a false recovery period followed by liver failure and death.
