Can Dogs eat Mushrooms? Everything you need to know!

Dogs will try to eat almost ANYTHING. No matter how disgusting it is, they’ll put it in their mouths. This is their way to explore the world. But what happens when your dog eats a mushroom?

Well, it DEPENDS on the mushroom.

Some mushrooms are poisonous to dogs, while others are not. Generally, the same mushrooms that are poisonous to us are poisonous to dogs. Vice versa, mushrooms that are edible by us can also be eaten by our 4 legged canine friends. While serious illness or death from mushrooms in dogs is rare, it DOES happen.

What to do if your Dog has eaten a Wild Mushroom

Let’s say you’ve spotted something strange in your dog’s mouth. Before you know it, it’s eaten a wild mushroom! What do you do? 

  1. Remain calm. It’s unlikely your dog has eaten a deadly poisonous mushroom. Regardless, assume it has until you’ve confirmed the safety of your pet.
  2. Look and Document Evidence of the Mushroom. Before you leave the scene, look for pieces of the mushroom. If you find any, take a picture of them from every possible angle. If possible, take the pieces with you. Mushrooms often fruit in patches, so search the area for more of the same species. Take pictures and a specimen if possible. This will help with identification.
  3. Head To The Veterinarian. It’s better to be safe than sorry. If you arrive soon enough, the vet may be able to induce vomiting. If not, they may be able to distinguish symptoms of mushroom poisoning.
  4. Try to Identify the Mushroom. Below we provide a list of common poisonous mushrooms. Consult this list. You can also google search “Poisonous Mushrooms of ________” filling it in with your region (country, state, country, etc.). Facebook groups can also help identify mushrooms via photos. Click here for the group “Poisons Help; Emergency Identification for Mushrooms and Plants”.  There is also a list of volunteers who will help identify potentially poisonous mushrooms. Also, search for a local group by searching for your region with the keyword mushroom.  You can ask if there are any poisonous mushroom fruiting in your area at the moment if you have no pictures.
  5. Watch for Symptoms, Wait for Identification, and Follow the Guidance of Your Vet. Your vet will know best as they may already have experience with poisonings in your area.

Can Dogs eat Store bought Mushrooms?

If you’re wondering whether dogs can eat the same mushroom you eat, they can! They can be a healthy addition to a dog’s diet when properly prepared. Keep in mind that we usually cook mushrooms with ingredients that are not healthy for dogs! 

Mushrooms that are safe for dogs include Shiitake, Oysters, Button Mushrooms, and Portabello. DO NOT feed your dog raw mushrooms as this is harmful to their digestive system. 

Can you give Dogs Medicinal Mushrooms?

Studies on medicinal mushrooms have not been conducted on dogs. For this reason, we DO NOT recommend it. However, many medicinal mushroom studies occur on smaller animals like mice. So some are likely safe.

If you do consider this, make sure you give an adequate dose based on body weight.
