re Pit Bulls Good Family Dogs 1

The question, “Can dogs eat mushrooms?” might seem simple enough, but the answer is surprisingly complex. Given that there are over 10,000 known species of mushrooms, it’s critical to know which ones are safe for your canine companion and which ones should be avoided, like the plague. Whether you’re a seasoned dog owner or new to the game, this blog post is designed to offer insights into this puzzling subject matter.

Why Mushrooms?

As a dog owner, you know that your fur baby loves to explore the world with their nose and mouth. This natural curiosity makes it essential to be well-versed in what’s safe and what’s not for dogs to ingest. Mushrooms can be particularly challenging to categorize because while some are completely harmless, others can be deadly.

More than Just Food

It’s not just about food either. Many of us have mushrooms growing naturally in our yards or nearby woods, making the odds of your dog encountering one quite high. Understanding the various types of mushrooms and their potential effects on your dog’s health can literally be a lifesaver.

Types of Mushrooms: The Good, the Bad, and the Ugly

Mushrooms are not created equal. Some are harmless and even nutritious, while others can cause everything from mild digestive issues to severe poisoning or death in dogs. Knowing which is which is crucial for the health and safety of your pet.

Edibles for Dogs

Common Edibles

  • White button mushrooms
  • Portobello
  • Shiitake 

These are the kinds of mushrooms you’ll typically find at the grocery store and are generally safe for dogs to eat in moderate amounts. They can even offer nutritional benefits like fiber and protein.

Preparation and Moderation

However, even these “safe” mushrooms should be cooked to break down any tough fibers and make them easier for your dog to digest. Additionally, because mushrooms can be rich and sometimes fatty, they should be given in moderation to avoid stomach upset or weight gain.

Toxic Types to Avoid


The Danger List

  • Amanita Phalloides (Death Cap)
  • Amanita Muscaria (Fly Agaric)
  • Gyromitra spp. (False Morels) These and several other types of mushrooms can be highly toxic to dogs and can cause severe poisoning or death.

Location and Identification

Toxic mushrooms often grow in wooded areas, so be extra vigilant if you take your dog hiking or camping. If you’re unsure about a mushroom, it’s always safer to err on the side of caution and prevent your dog from ingesting it. Some types are hard to differentiate, even for experts.

Symptoms of Poisoning in Dogs


Mushroom poisoning in dogs can manifest in various ways, depending on the type and the amount ingested. Quick identification of symptoms is crucial for effective treatment.

Immediate Signs

  • Salivation
  • Weakness These are generally the first signs that your dog may have ingested a toxic mushroom. Immediate veterinary attention is crucial at this point.

Delayed Symptoms

  • Seizures
  • Coma These symptoms can take several hours to days to appear, and they often indicate severe poisoning that requires immediate emergency treatment.

What To Do if Your Dog Eats a Toxic Mushroom


If you suspect that your dog has eaten a toxic mushroom, time is of the essence. The faster you act, the better the chance for your dog’s recovery.

Emergency First-Aid

  • Remove any remaining mushroom pieces from your dog’s mouth.
  • Keep a sample of the mushroom for identification.
  • Contact your veterinarian or emergency pet poison hotline immediately.

Veterinary Treatment

Your vet may induce vomiting, administer activated charcoal to absorb the poison, or give intravenous fluids and other medications to support your dog’s vital functions. The specific treatment will depend on the type of mushroom and the severity of the poisoning.

Additional Resources: Books, Apps, and Websites


Why Additional Resources Matter

Being a responsible pet owner involves ongoing education. Mushrooms are a complex subject, and while this guide is comprehensive, additional resources can deepen your understanding and keep you updated on new findings or species.


There are several excellent books on mushrooms, including guides that specifically address pet safety. Some highly recommended titles include:

  • “Mushrooms of North America” by Roger Phillips
  • “All That the Rain Promises and More: A Hip Pocket Guide to Western Mushrooms” by David Arora
  • “Mushrooms: A Folding Pocket Guide to Familiar North American Species” by James Kavanagh

Apps and Websites

Modern technology makes it easier than ever to identify mushrooms. Various apps allow you to take a photo and get immediate identification. However, these should be used cautiously and never replace professional advice. Some credible websites for information include:


Can I Feed My Dog Truffle?

While truffles are considered a delicacy for humans, they are not recommended for dogs. Truffles contain compounds that can be difficult for a dog to digest and may lead to gastrointestinal issues.

Moreover, truffles are often prepared with oils, seasonings, or other ingredients that may be harmful to dogs. Therefore, it’s best to avoid feeding truffles to your pet.

What About Mushroom Supplements for Dogs?

Some supplements designed for dogs do contain mushroom extracts, claiming to offer health benefits like immune support. However, these supplements should only be administered under the guidance of a qualified veterinarian.

It’s important to ensure that the supplement is specifically formulated for dogs and does not contain any toxic mushroom varieties.

Are Canned Mushrooms Safe for Dogs?

Canned ones are generally cooked and, therefore, easier to digest than raw mushrooms. However, they are often preserved in salt water, which makes them high in sodium. High sodium intake can be harmful to dogs, leading to conditions like hypertension.

If you are considering feeding your dog canned mushrooms, it’s advisable to rinse them thoroughly to remove excess sodium and consult your vet for guidance.

Can I Use Mushrooms in Homemade Dog Food?

Yes, you can use them in homemade dog food, but it’s important to stick to the types that are known to be safe for dogs, like white button, portobello, and shiitake variation. Always cook them thoroughly to aid in digestion.

However, keep the portion small and make sure to consult with your veterinarian to ensure that you are meeting your dog’s nutritional needs effectively.

What’s the Best Way to Remove Mushrooms from My Yard?

If you have mushrooms growing in your yard where your dog plays, the safest course of action is to physically remove them. Wear gloves to avoid skin irritation and use a shovel to dig them up, taking care to get the root as well.

Dispose of them in a sealed bag. For a more permanent solution, consult with a lawn care specialist who can advise on changes to soil composition or other methods to deter mushroom growth.

Can Cooking Destroy the Toxins in Poisonous Mushrooms?

Cooking may break down some harmful substances in certain foods, but when it comes to poisonous mushrooms, cooking is generally not effective in eliminating toxins. Some toxins are extremely heat-stable and will remain toxic even after cooking.

Therefore, it’s crucial to ensure the type of mushroom is safe for canine consumption before including it in your dog’s diet.

Final Words

The world is full of wonders for our canine companions to explore, but not all of these are safe. Mushrooms are a perfect example of this dichotomy. While some can be a tasty treat or even a nutritious supplement to their diet, others can spell disaster.
