  1. Low fat, low salt: Shiitake mushrooms are low in calories. They’re ideal for maintaining a healthy body weight. They also make your dog feel ‘fuller’, which stops overeating.

  2. Contains omega-6 acids: Shiitake mushrooms contain lentinan. This is an omega-6 essential fatty acid. Lentinan supports the immune system by protecting against bacteria and viruses. It also fights against cancer. Studies show it reduces cancerous cells.

  3. Packed with vitamins: Shiitake mushrooms are full of vitamins. They contain B vitamins (essential for energy, brain function and hormone regulation), and vitamin D, which maintains healthy bones and hormones. Dogs need a food source of vitamin D as they can’t make it from sunlight.

  4. Excellent source of protein: They are a wonderful source of protein and contain a variety of amino acids, which are essential for many processes in the body.

  5. High in fibre: Fibre is an important part of your dog’s diet, but many processed dog foods contain crude ash of unknown origin to make up the fibre content. Shiitake mushrooms contain beta glucan. This is a soluble dietary fibre that stabilises blood sugar, lowers cholesterol and aids digestion.

  6. Lowers cholesterol: Shiitake mushrooms contain eritadenine. This compound lowers cholesterol. Dogs on high-fat diets are prone to high cholesterol levels.

  7. Good for healthy digestion: Shiitake mushrooms high in fibre, but also contain around 30 different enzymes that aid digestion. The most important one of these is amylase. Amylase breaks down starch molecules (a high-starch diet is common amongst many dogs).

  8. Promotes healthy skin and coat: Shiitake mushrooms have high levels of trace minerals such as selenium. Selenium helps with skin and coat health. It also contains zinc, which aids healing, and copper, which promotes the absorption of iron and increases red blood cell production. Healthy red blood cells encourage hair growth and strong tissues.

  9. Boosts the immune system: Shiitake mushrooms contain many compounds that boost the immune system, including a protein called interferon. Interferon prepares the body to fight against viruses, bacteria and cancerous cells.

Dos and don’ts of dogs eating shiitake mushrooms


You must cook shiitake mushrooms before feeding them to your dog. Chop the mushrooms up into small, bite-sized pieces to prevent choking. You can steam or boil the mushrooms, but don’t fry them or add oil or any seasoning. Add water to dehydrated or dried mushrooms and heat through.

Always serve in small quantities. Start off feeding infrequently with small amounts. Some dogs are allergic to mushrooms. Add a few cooked ones to their diet, depending on the size of the dog. Dogs benefit from a daily dose of mushrooms (3-4 mushrooms for an average-sized dog, or one or two teaspoons of dried).


Don’t feed raw or uncooked mushrooms to your dog. Dogs struggle to digest the fibre in uncooked mushrooms.

Don’t replace your dog’s diet with mushrooms.

Don’t feed your dog too many mushrooms.

Watch out for allergic reactions:

  • Vomiting or diarrhea

  • Bloated stomach

  • Itchy skin

  • Chronic gas

  • Severe allergic reaction (anaphylaxis)


Shiitake mushrooms contain a variety of health benefits for dogs. They are perfectly safe to eat so long as you cook them plainly with no extra seasoning or oil. Feed in small quantities and never replace a meal with all mushrooms. When giving for the first time, feed a tiny amount and watch carefully for any adverse symptoms.
