Are Mushrooms Safe for Dogs? What Every Pet Owner Needs to Know

Many dog owners wonder if it's okay to share mushrooms with their pets. The answer depends on the type of mushroom, how it's prepared, and where it comes from. Let's break down the facts so you can keep your furry friend safe.

Safe Mushrooms: Store-Bought Varieties

Dogs can safely eat certain mushrooms—specifically, those commonly found in grocery stores. These include:

• White button
• Cremini
• Portobello
• Baby bella
• Shiitake
• Maitake
• Porcini
• Enoki
• King trumpet
• Oyster
• Lion’s mane

If you want to offer these to your dog, serve them plain—no seasonings, oils, butter, onions, garlic, or other additives. Both cooked and raw plain mushrooms are generally considered safe. Some dogs digest cooked mushrooms more easily.

Portion control matters. Mushrooms should only be an occasional treat and never exceed ten percent of your dog's daily caloric intake. Dogs don't need mushrooms as part of a balanced diet; think of them as a rare snack rather than a staple food.

The Dangers of Wild Mushrooms

Wild mushrooms are a different story—and they’re often deadly.

The challenge is that many wild mushrooms are highly toxic to dogs. Even a small bite can cause severe illness or death. Some of the most dangerous types include:

• Amanita phalloides (death cap)
• Amanita bisporigera (death angel)
• Amanita gemmata (jeweled death cap)
• Amanita muscaria (fly agaric)
• Amanita pantherina (panther cap)
• Gyromitra esculenta (false morel)
• Clitocybe dealbata (sweating mushroom)
• Galerina marginata (funeral bell)
• Inocybe species
• Cortinarius rubellus (deadly webcap)

Mushroom identification is tricky—even for experts. For safety's sake, treat all wild mushrooms as potentially poisonous. Remove any that appear in your yard or places where your dog plays.

Mushroom Poisoning: Symptoms and What To Do

Toxic effects can show up within minutes or hours—or sometimes take over twelve hours to appear. Symptoms vary by mushroom species and dose but may include:

• Vomiting or diarrhea (sometimes bloody)
• Drooling excessively
• Painful abdomen or restlessness
• Lethargy or weakness
• Tremors, seizures, muscle spasms
• Lack of coordination or staggering gait (ataxia)
• Cognitive changes—disorientation, odd behavior
• Collapse or coma
• Liver/kidney failure signs: jaundice (yellow skin/gums/eyes), increased thirst or urination, difficulty breathing, rapid heart rate
• Death in severe cases

If you suspect your dog has eaten a wild mushroom:

1. Scoop out any visible pieces from their mouth immediately.
2. If possible, collect a sample of the mushroom using gloves or a bag.
3. Call your veterinarian or an emergency animal hospital right away—do not wait for symptoms!
4. Avoid inducing vomiting unless instructed by a vet.

Avoiding Trouble: Prevention Tips for Pet Owners

• Supervise dogs during walks—especially in areas where wild mushrooms grow.
• Regularly check and remove wild fungi from yards and gardens.
• Teach the "leave it" command so your dog ignores suspicious items outside.
• Use leashes in parks and forests during mushroom season.

Mushrooms as Treats: Guidelines for Safety

If you want to share store-bought mushrooms with your pet:

• Select only plain white button, cremini, portobello, shiitake, maitake, porcini, enoki, king trumpet, oyster, or lion’s mane varieties.
• No seasoning—skip salt, pepper, garlic powder, onions, butter/oil.
