Can Dogs Eat Mushrooms? The Safe and Toxic Types
TL;DR: Yes, dogs can eat plain, store-bought mushrooms like white button or portobello. Wild mushrooms are highly toxic and can be fatal, so never let your dog eat mushrooms growing in your yard or on a trail.
If you drop a plain white button mushroom on the kitchen floor and your dog snaps it up, you don't need to panic. Store-bought mushrooms are generally safe for dogs. The danger comes from wild mushrooms, which can be incredibly toxic and difficult to identify even for experts. Dogs explore the world with their noses and mouths, so a mushroom growing in the grass can look like a fun snack. The rule of thumb is simple: grocery store mushrooms are fine, but treat every wild mushroom as a veterinary emergency.
Nutritional Value for Dogs
Mushrooms aren't a necessary part of a dog's diet, but they do offer some nutritional benefits. They contain vitamins B and D, minerals, and antioxidants. They are also low in calories, fat-free, and cholesterol-free. They can be a healthy occasional treat, but your dog should be getting all their essential nutrients from their regular, balanced dog food.
How to Safely Feed Mushrooms
If you want to share mushrooms with your dog, stick to plain, unseasoned varieties from the supermarket. White button, cremini, portobello, and shiitake are all safe options. You can serve them raw or cooked, but make sure they are completely plain. We rarely eat mushrooms on their own. They are usually cooked in butter, oil, garlic, or onions, all of which can upset your dog's stomach or be outright toxic.
Wild mushrooms are a completely different story. Species like the Death Cap (Amanita phalloides) or Fly Agaric (Amanita muscaria) are highly poisonous to dogs. Some toxic mushrooms even have a fishy odor that dogs find appealing. Because it's so hard to tell a safe wild mushroom from a deadly one, veterinarians recommend removing any mushrooms growing in your yard and keeping a close eye on your dog during walks in wooded areas.
Portion Guide by Dog Size
Mushrooms should only be an occasional treat. Here is a quick guide on how much to offer:
| Dog Size | Portion Size |
|---|---|
| Small dogs (under 20 lbs) | 1/4 to 1/2 of a small mushroom |
| Medium dogs (21-50 lbs) | 1/2 to 1 whole small mushroom |
| Large dogs (over 50 lbs) | 1 whole small mushroom or a slice of a larger one |
Signs of a Bad Reaction
If your dog eats a wild mushroom, or if they have an unexpected reaction to a store-bought one, watch for these symptoms:
- Vomiting or diarrhea
- Excessive drooling
- Weakness or lethargy
- Staggering or uncoordinated movements
- Abdominal pain
If you suspect your dog has eaten a wild mushroom, contact your veterinarian or an animal poison control center immediately. If possible, bring a sample of the mushroom wrapped in a damp paper towel to help the vet identify the toxin.
A Note from Maggie
Alice has a stomach of steel when it comes to most things, but her allergies mean we keep her diet pretty strict. Dodo is still in her puppy phase where everything on the ground is a potential snack. We spend a lot of time walking in parks, and I've become hyper-aware of the little brown mushrooms that pop up in the grass after it rains. I always steer her clear of them. It's just not worth the risk when I can give her a safe, plain mushroom from the fridge instead.
