Can dogs eat mushrooms? Learn the 7 shocking truths about safe and toxic mushrooms for dogs, plus vet-approved tips to keep your pup healthy and happy.
Introduction:
If you’ve ever caught your furry friend sniffing around the backyard or the forest floor, you’ve probably wondered: can dogs eat mushrooms safely? Mushrooms pop up everywhere—from pizza toppings to your garden after the rain—and while they’re delicious for humans, not all mushrooms are friendly to our canine companions.
The truth is, some mushrooms are completely harmless to dogs, while others can be dangerously toxic. Knowing the difference could literally save your dog’s life. In this article, we’ll explore the seven shocking truths about mushrooms and dogs, which types are safe, which are deadly, and what to do if your dog accidentally eats one.
Understanding the Basics — What Are Mushrooms?

Mushrooms are fungi, not plants. They come in thousands of varieties, from edible button mushrooms to poisonous species like Amanita phalloides (the “death cap”). For humans, edible mushrooms are full of nutrients such as fiber, antioxidants, and vitamins. But when it comes to dogs, things get tricky.
Dogs Have Different Digestive Systems
While humans can digest mushrooms easily, dogs process foods differently. Their digestive systems are designed for animal proteins, not complex fungi. That’s why even some edible mushrooms may cause stomach upset in dogs.
Natural Instincts Aren’t Always Safe
Dogs are curious creatures. Their sense of smell might attract them to mushrooms growing outdoors. Unfortunately, they can’t tell the difference between edible and toxic types, which raises the question—can dogs eat mushrooms without risk? The short answer: only some, and under specific conditions.
7 Shocking Truths About Dogs and Mushrooms
Let’s uncover the truth behind this controversial question—can dogs eat mushrooms safely? You might be surprised by what you’ll learn below.
1. Not All Mushrooms Are Safe for Dogs
Just because a mushroom is safe for humans doesn’t mean it’s safe for dogs. Store-bought mushrooms like white button, portobello, or cremini are generally safe if cooked plain. But wild mushrooms are a different story—many are highly toxic to dogs.

2. Wild Mushrooms Can Be Deadly
If your dog eats wild mushrooms during a walk or in your yard, contact a vet immediately. Certain species like the death cap, fly agaric, and false morel can cause liver failure, kidney damage, or even death.
Symptoms of mushroom poisoning include:
- Vomiting and diarrhea
- Drooling
- Tremors or seizures
- Yellow gums or eyes (signs of jaundice)
- Weakness and lethargy
Even a small bite can be fatal, so it’s never worth taking chances.
3. Cooked Mushrooms Are Safer—but Still Require Caution
You might think, “Well, I’ll just cook them for my dog.” While cooked mushrooms like white or cremini are less risky, they should always be served plain—no salt, butter, garlic, or onion, which are toxic to dogs.
The Right Way to Feed Mushrooms
- Wash them thoroughly to remove dirt or chemicals
- Cook without oil, butter, or seasoning
- Cut into small, digestible pieces
- Feed occasionally as a treat, not a full meal
4. Mushrooms Offer Health Benefits—When Safe
Yes, dogs can eat mushrooms—the safe kind—in moderation. They can even benefit from nutrients like antioxidants that support immune health, vitamin D for strong bones, fiber for digestion, and beta-glucans that may improve heart health.
Some pet food brands even use medicinal mushroom extracts like reishi, shiitake, or maitake to boost immunity and support overall wellness.

5. Dogs Can’t Identify Toxic Mushrooms
Here’s a shocking fact: even the best-trained dogs can’t distinguish safe from poisonous mushrooms. Many toxic varieties look similar to edible ones. That’s why responsible pet owners should keep dogs away from all wild mushrooms—no exceptions.
If you ever ask yourself can dogs eat mushrooms they find outside, the answer is always a firm no.
6. Mushroom Poisoning Requires Immediate Action
If your dog eats an unknown mushroom, don’t wait for symptoms. Time is critical.
Here’s what to do immediately:
- Remove your dog from the area to prevent more ingestion.
- Try to identify the mushroom or take a photo.
- Call your vet or the Pet Poison Helpline (1-855-764-7661).
- Do not try home remedies—they can make it worse.
- Bring a sample of the mushroom to the vet for analysis.
Even if your dog seems fine, toxins may take hours to show effects, so prompt action matters.
7. Prevention Is Better Than Cure
The best answer to “can dogs eat mushrooms?” is “only safe ones you provide.” Keep your yard clear of wild mushrooms, supervise your dog during walks, and never allow them to nibble on unknown fungi.
You can also teach the “leave it” command to stop them from eating unsafe objects outdoors.
