About Mushroom
In pet food, mushroom refers to cultivated edible fungi added for fiber, trace nutrients, and beta-glucan compounds, not the wild mushrooms found outdoors.
Mushrooms are used in pet foods as a low‑calorie vegetable ingredient and flavor enhancer that adds dietary fiber and bioactive components such as beta‑glucans, antioxidants, B vitamins, and minerals. These compounds can modestly support immune health and antioxidant status in dogs and cats, but mushrooms should be included only in moderation and sourced/processed safely because some wild species are toxic and some pets may experience allergies or gastrointestinal upset.

- cultivated edible fungi (e.g. shiitake, maitake, turkey tail)
- Primary role
- fiber and beta-glucan source, flavor component
Why it's used
Culinary mushroom species contribute soluble fiber, B vitamins, and polysaccharides called beta-glucans, which are commonly studied for their interaction with immune cell activity. Formulators also use mushrooms for their savory flavor contribution and low caloric density relative to other inclusions.
Common concerns
- Confusion with wild mushrooms The mushrooms used in commercial pet food are cultivated culinary species and are a different category from wild mushrooms, which UC Davis and the ASPCA note can be hepatotoxic, neurotoxic, or nephrotoxic if a dog encounters and eats them outdoors.
- GI upset Even edible mushroom species can cause digestive upset in some individual pets, particularly in larger amounts or if poorly cooked.
- Limited dosing evidence Search results summarizing available research note that the immune-related potency of mushroom-derived beta-glucans has been described as lower than some yeast-derived beta-glucans, so effect sizes at typical pet food inclusion levels are not well established.
Also relevant
If a pet eats a mushroom found outdoors rather than one in commercial food, veterinary guidance is to treat it as a potential emergency and contact a veterinarian or poison control rather than wait for symptoms.
