Can Dogs Eat Mushrooms?

Can dogs eat mushrooms? This is perhaps one of the most difficult questions veterinarians may have to answer during their clinical consultations. Yummy and nutritious to humans, mushrooms do have various health benefits for us, but new studies show that they can be just as beneficial to our dogs and cats as well.

You’ve probably heard of various holistic vets preaching about the many medicinal uses of mushroom for dogs. While, on the other side of the scale, you may have heard of the many cases of mushroom toxicities in dogs.  The internet is full of various stories about mushroom consumption in dogs and so things can get a little confusing.  So, here we will look at what studies and research says about “Can dogs eat mushrooms?”

What Studies Say…

A 2012 study analyzed mushroom poisoning cases in dogs. The study concluded by stating that there are thousands of mushroom species available in North America. However, of these thousands, less than a 100 are considered toxic to dogs—and of these 100, only mushrooms that fall under the genus Amanita are liable for mushroom poisonings in dogs.

In contrast, another study done in 2012 looked to examine the potential benefits that mushrooms may have in treating cancer in human patients. Interestingly enough, this research project used animal models—in this case, dogs, to examine the efficacy of a bioactive chemical known as Polysaccharopeptide (PSP).

PSP is the main active chemical found in the mushroom species known as Coriolus versicolor, which is commonly known as Turkey tail mushroom. In this study, researchers chose to treat dogs with canine hemangiosarcoma (liver and spleen cancer) with PSP. Most noteworthy, it was found that PSP did indeed slow down the progression of metastases of the cancer cells, thus increasing the longevity of these dogs.

So can dogs eat mushrooms? Yes! But, they cannot consume all mushrooms. Rather, dogs may only be tolerant to a few kind of mushroom species.

Mushrooms are rich in bioactive compounds, which include alpha and beta-glucans, enzymes, ribonucleases, antioxidants, and more!

Reishi and Maitake mushrooms have been extensively studied during the last few years. One study demonstrated that the active compounds of Maitake mushrooms were able to reduce the growth of three types of cancer cells in dogs, this includes cancer mammary gland cancer, connective tissue cancer, and lymphoma cells.
