Factors To Consider Before Buying Mushrooms For Dogs

Type of Mushrooms

Not all mushrooms are edible. While some are highly beneficial for health, others can be dangerous or even fatal. For that reason, never let your dog eat mushrooms in the wild. However, you can safely give your dog mushrooms found in the grocery store, like button, portobello, and cremini. And to give your pup an even heartier dose of mushroom goodness, feed them turkey tail, shiitake, lion’s mane, cordyceps, maitake, and Reishi. The easiest way to give your dog mushrooms is via a powder or chew supplement. 


Always ensure the supplements or treats you give your dog are of the utmost quality. A disreputable product or one that contains artificial ingredients may do more harm than good to your pup’s health. Your best bet is to choose a product formulated by veterinarians or manufactured under their supervision. Choosing organic options also ensures you’re getting a cleaner and higher-quality product. 


Don’t forget to take any allergies your dog may have into consideration. Some dogs may be allergic to a certain type of mushroom or maybe all types of mushrooms. If you notice any odd changes after giving them mushrooms, immediately stop or consult your vet. When shopping for mushroom supplements for dogs, don’t forget to check the entire ingredients listing for any of your pup’s allergens.

Frequently Asked Questions About Mushrooms and Dogs 

Are mushrooms bad for dogs?

No, mushrooms are not bad for dogs. They’re known to boost immune systems for overall better health. However, some dogs may not like mushrooms and resist them simply because of the taste or smell. Some dogs may be allergic to mushrooms too. In such cases, avoid mushrooms for your dog. Otherwise, store-bought mushrooms and supplements can be great for dogs! 

Do mushrooms give dogs stomach problems?

Mushrooms are known to resolve digestive issues and improve overall gut health. They regulate bowel movements and fight the causes of bad breath. However, if your dog is having stomach problems because of mushrooms, they might have an allergy. In that case, you should immediately stop giving them any mushroom supplement and consult your vet if the situation worsens. If your dog isn’t allergic to mushrooms, try cooking them before feeding to your dog, as this can soften the tough outer layer of the mushroom that some dogs have trouble digesting. 

Do dogs like mushrooms?

Some dogs do like mushrooms and consume them without any difficulty, while others don’t even like the smell. Finding out if your pup enjoys mushrooms is a journey you’ll have to take together. And even if your dog doesn’t love mushrooms, most mushroom supplements won’t have a pungent smell and offer a mild flavor, so your best friend can still enjoy the benefits of mushrooms for dogs!  

What mushrooms are good for dogs?

Never feed dogs wild mushrooms. It’s too risky as there are so many poisonous and even fatal ones out there. However, dogs can safely eat store-bought mushrooms such as button, portobello, and cremini types. And if you’re into enjoying specialty mushrooms, you and your pup can snack on turkey tail, shiitake, lion’s mane, cordyceps, maitake, and Reishi mushrooms together. Some of these fancier mushrooms might be hard to get ahold of, but supplements will let you give your dog the benefits of multiple types of mushrooms.

Why are mushrooms beneficial?

Mushrooms are highly beneficial for both humans and animals as they contain anti-inflammatory and antioxidant properties that improve digestive health and build up the immune system. Packed with the power of B vitamins, vitamin D, selenium, fiber, beta-glucans, and so much more, these little fungi provide the body with a wealth of nutrients that not only boost organ systems but also slow cell damage caused by certain illnesses.  

Can mushrooms prevent cancer in dogs?

Mushrooms contain beta-glucans, a substance proven to support the immune system and prevent the spread of early cancers. Adding mushrooms or mushroom supplements to your dog’s daily diet will ensure your pup’s internal health is working at optimal levels while their strengthened immune system stands a better chance at fighting cancer growth. 

Can I give raw mushrooms to my dog?

Some experts say your can feed your dogs small amounts of raw mushroom, but others maintain you should cook mushrooms before feeding them to your dog. Both raw and cooked mushrooms are rich in vitamins and antioxidants, but cooking your mushrooms softens the tough outer layer for better digestion.
