Dogs On Shrooms

Updated: Mar 14

This may sound a bit weird. You’re probably thinking, “aren’t mushrooms toxic?! Not to worry, there are 4 types of mushrooms: toxic, hallucinogenic, culinary, and medicinal.

Medicinal or culinary mushrooms are used for humans and dogs, not the backyard mushrooms that are taught not to eat.

⚠️Toxic mushrooms can be hard to identify if wildcrafting. Mushrooms should always be purchased from a reliable source.

Mushrooms are fungi that are added to the vegetable category. These fungi have been used in Traditional Chinese medicine for the medicinal properties of mushrooms for centuries.


Mushrooms are filled with antioxidants that help the body fight against free radicals, playing a significant role in heart disease and cancer. Antioxidants also help slow aging effects and boost the immune system. Mushrooms happen to be very rich in an antioxidant called selenium.


Mushrooms are a major anti-cancer food, and this is due to Beta-glucan, which is the active medicinal property. Beta-glucan is a soluble fiber (a polysaccharide). It’s found in the cell walls of certain substances, especially mushrooms. Beta-glucan is also found in many types of seaweed, algae, some cereals (grains), and yeast. However, only beta-glucan from certain mushrooms has immune-modulating and anti-tumor properties.

Oyster and Shiitake mushrooms have the most Beta-Glucan properties out of the mushrooms kingdom.

A study done by Penn State studied the effects on hemangiosarcoma, a type of cancer, and found that dogs treated along with turkey tail mushroom had the longest survival time than any dog reported with the disease!

Some say that beta-glucans are the oldest immune-stimulating foods that we know of! This is due to the powerful effects beta-glucan has on the immune system. Beta-glucans bind and help specific immune cells attack the body’s invaders.

When dogs are fed beta-glucans, the immune cells become more active, powerful, and effective at attacking and destroying invaders.


Mushrooms are jam-packed with B vitamins such as riboflavin, niacin, and pantothenic acid. The combination of these 3 is fantastic for heart health.

Riboflavin (Vitamin B2) is a water-soluble vitamin needed for energy production, coenzyme activity, cell function, and growth and development.

Niacin (Vitamin B3) is another water-soluble vitamin essential for regulating digestion, stress responses, boosting brain function, and DNA repair.

Pantothenic acid (Vitamin B5) is also a water-soluble vitamin needed for coenzymes, carrier proteins, metabolism, and helps convert fats, carbs, and proteins into energy.

Looking For Shrooms

There is a common practice where companies will only grow and add the mycelium and a small part of the mushroom in the supplement with the actual medicinal properties. To have the most potent effect, you must ensure you’re feeding the mycelium and the fruiting body.

The fruiting body contains the beta-glucan and makes the mushroom so medicinally powerful! Without it, there are no medicinal benefits.

A 2017 study tested 19 mushroom products on the market. Not surprisingly, only five tested following their labels. That means only 5 of the 19 could be identified as mushrooms. The study concluded, the quality consistency of G. lucidum dietary supplements in the U.S. market was poor.

⚠️ It’s important to be aware that not all mushrooms are grown the same. Many companies will only grow the mycelium, made in a lab (grown on grains like oats and rice rather than on wood), and only a tiny part of the mushroom with significantly lower medicinal properties.

Companies such as Four Leaf Rover add the fruiting body into their mushroom supplement to ensure the mushrooms deliver the most potent punch of nutrients and benefits. But the easiest way to ensure a quality mushroom supplement is making your own mushroom broth!
