When Can Dogs Eat Mushrooms?

Sticking to store-bought mushrooms for your dog is the best way to go unless you’re a mycologist or a biologist who studies the fungi.

So if you sauté some mushrooms in some olive oil and want to give your dog a little, it should be okay as long as your vet approves of it. Just be sure that you are not mixing mushrooms with any other vegetables or seasonings that could be potentially toxic to your dog.

Plain mushrooms are the best way to go to ensure that your dog is not affected by any of the seasonings in the dish. Mushrooms are also a great source of vitamin B and minerals such as potassium.

How to Add Mushrooms to Your Dog’s Diet

Mushrooms, like any other food for your pet, should be gradually introduced to prevent an upset stomach. Over a period of several days, you should slowly increase the amount that you’re feeding your dog, and if you notice any signs of illness, stop immediately. 

You should also be aware that you should introduce only one new food at a time so you will be able to identify the culprit if your pet ends up with any signs of illness or upset stomach.

Fresh and dried mushrooms, in general, contain more beneficial nutrients than preserved or canned mushrooms. Since dogs do not contain the enzymes needed to break down the fiber as well as some of the sugars in mushrooms, you should cook the fresh mushrooms before feeding them to your dog to better enable digestion.

The Bottom Line

Store-bought mushrooms have just as many health benefits for your dog as it does for you. They are also safe to share with your dog, and if you’re snacking on button mushrooms as you prepare dinner, feel free to toss your pup a piece or two. However, as we mentioned earlier, it’s always best to cook or steam the mushrooms to help break down the fibers and sugars so that your dog will be able to digest them better. So mushrooms are perfectly safe for your dog as long as they are free from any seasonings and sauces.
