Dogs can eat some types of mushrooms, but not all. While some mushrooms are safe, they are not a necessary part of a dog's diet and should be given in moderation. Mushrooms that are safe for human consumption are generally safe for dogs, and store-bought mushrooms such as white buttons or portabellas are usually fine for dogs to eat raw or cooked. However, some dogs can be allergic to mushrooms, even if they are considered safe, and wild mushrooms should be avoided as many are toxic and can be deadly. If you plan to add mushrooms to your dog's diet, it is recommended to consult your vet first and avoid heavy seasonings or sauces.

Safe mushrooms for dogs
While some mushrooms are safe for dogs to eat, it is important to note that they are not a necessary part of a dog's diet and should be offered in moderation. Mushrooms that are safe for human consumption are generally safe for dogs. These include raw, cooked, and organic mushrooms bought from a supermarket or grocery store. However, it is important to avoid feeding dogs wild mushrooms as they can be poisonous and cause serious side effects or even death.
If you plan to add mushrooms to your dog's diet, it is recommended to consult your veterinarian first. Mushrooms should be served plain without any heavy seasonings, sauces, salt, oils, butter, garlic, or onions, as these can upset your dog's stomach and be harmful. When feeding mushrooms to dogs, it is important to cut them into small pieces to prevent choking hazards.
It is crucial to monitor your dog's surroundings and supervise them when outdoors to prevent them from consuming wild mushrooms. Wild mushrooms can be toxic to dogs, and it can be difficult to distinguish toxic varieties from non-toxic ones. If you suspect your dog has ingested a wild mushroom, contact your veterinarian immediately and provide a sample of the mushroom if possible.
Some of the wild mushrooms that are poisonous to dogs include:
- Death Cap (Amanita Phalloides)
- Destroying Angel (Amanita Virosa)
- Fool's Funnel (Clitocybe Rivulosa)
- Panther Cap (Amanita Pantherina)
- Angel's Wings (Pleurocybella Porrigens)

Mushrooms toxic to dogs
While some mushrooms are safe for dogs to eat, others are toxic and can cause serious or even life-threatening illness. It is very difficult to identify which mushrooms are safe and which are poisonous, so it is generally recommended that dogs avoid eating mushrooms altogether. If your dog has ingested a wild mushroom, you should treat it as a veterinary emergency and contact your veterinarian, animal poison control centre, or emergency veterinary hospital immediately.
There are over 10,000 species of mushrooms in the United States, but only about 100 are toxic. However, it can be challenging to distinguish between toxic and non-toxic mushrooms, as there is no simple test to differentiate between the two. Wild mushrooms that seem to cause the most problems include Amanita phalloides (commonly known as "death cap"), Galerina marginata ("deadly Galerina" or "Galerina autumnalis"), Inocybe spp., and Clitocybe dealbata mushrooms. The Amanita species is the deadliest, causing liver failure and subsequent kidney failure. Other toxic mushrooms are often grouped based on the clinical reactions they cause, which can include gastrointestinal issues such as vomiting, diarrhoea, and abdominal pain, as well as allergic reactions such as hives, itching, or difficulty breathing.
Mushrooms that are purchased from a supermarket or other shops are generally safe for dogs to eat in small amounts. These mushrooms are typically fine for dogs when raw, cooked, or plain, but should not be given to dogs if they are seasoned or cooked with other ingredients such as onions, garlic, salt, butter, or oil, as these can upset your dog's stomach. It is also important to note that dried mushrooms of any kind, even after being reconstituted, should be avoided as they can contain preservatives and additives that can cause allergic reactions or gastrointestinal upsets.

Symptoms of mushroom poisoning
While there are over 10,000 species of mushrooms in the United States, only about 100 are toxic. However, it can be challenging to identify mushrooms and determine which are safe and which are poisonous. Therefore, it is best to treat any mushroom ingestion by your dog as a medical emergency. If your dog has ingested any wild mushrooms, seek immediate veterinary care.
Clinical signs of mushroom poisoning in dogs may appear quickly (within 15-30 minutes after ingestion) or be delayed for up to 24 hours. It may take 2-3 days to see evidence of liver and kidney failure. Common clinical signs of mushroom poisoning include vomiting, diarrhoea, tremors, and seizures. Other possible symptoms include increased drinking and urination, dehydration, muscle twitching, and increased heart rate. In severe cases, mushroom poisoning can lead to liver and kidney failure, coma, and even death.
The symptoms and severity of mushroom poisoning in dogs depend on the species of mushroom consumed and the toxins they contain. Some mushrooms cause gastrointestinal distress, leading to vomiting and diarrhoea. Others affect the liver, resulting in liver failure, which can be deadly. These include the Amanita species, commonly known as "death cap" or "death angel". With these mushrooms, symptoms may be delayed by 6-12 hours, giving a false sense of security before progressing to liver failure and potentially death within a few days.
Nephrotoxic mushrooms affect the kidneys and can cause nausea, vomiting, loss of appetite, increased drinking and urination, and dehydration. Additionally, some mushrooms can cause neurological symptoms, such as psilocybin ("magic") mushrooms, hydrazines, and isoxazole mushrooms. The onset of symptoms with these mushrooms is typically rapid, often within 30-90 minutes.

Treatment for mushroom poisoning
While most mushrooms are harmless, some can be toxic and even deadly for dogs. If you suspect your dog has eaten a wild mushroom, it is important to act quickly and seek veterinary help immediately. Here are some steps to take for treatment:
Identify the Mushroom
If possible, try to identify the type of mushroom your dog has ingested. Take pictures or collect a sample of the mushroom, being sure to handle it with caution and avoid direct contact. You can use online resources or social media groups dedicated to mushroom identification to help with this process. However, do not delay treatment for your dog while trying to identify the mushroom.
Contact a Veterinarian
Reach out to your veterinarian, an animal poison control centre, or an emergency veterinary hospital. Provide them with as much information as possible about the suspected mushroom, including any pictures or samples you have. They may involve a toxicologist or mushroom expert in your dog's care.
Induce Vomiting
If the ingestion is recent, your veterinarian may induce vomiting to prevent the absorption of toxins. They may also administer activated charcoal for the same purpose.
Supportive Care
Supportive care may include intravenous crystalloids, oral GI protectants, or sedation. In more severe cases, inpatient supportive care such as IV fluids and liver-supportive medications may be necessary.
Specific Antidotes
In some cases, specific antidotes or drugs may be administered to counteract the toxin. For example, silibinin has been shown to increase survival rates when administered intravenously. However, the availability of certain antidotes may vary by region.
Remember, it is always best to consult a veterinarian before adding mushrooms to your dog's diet. Even mushrooms that are safe for human consumption can be toxic to dogs when combined with certain seasonings or sauces. Always exercise caution and prioritize your pet's health and safety.

Health benefits of mushrooms for dogs
While some mushrooms are toxic to dogs, many are safe and offer a range of health benefits. Medicinal mushrooms, in particular, are known to have healing abilities and can be used to treat various health issues in dogs.
Mushrooms are a good source of vitamins and minerals, including B vitamins, vitamin D, potassium, copper, and selenium. They also contain antioxidants, which help to reduce oxidative stress and support cellular health by neutralizing harmful free radicals. In addition, mushrooms are a source of both soluble and insoluble dietary fiber, which can support digestive health, help regulate bowel movements, maintain healthy gut bacteria, and prevent constipation.
Some specific types of medicinal mushrooms and their benefits include:
- Reishi mushrooms (Ganoderma lucidum), which are known for their immune-modulating properties and contain polysaccharides, beta-glucans, and triterpenoids.
- Turkey tail mushrooms (Trametes versicolor), which are rich in polysaccharides and beta-glucans and are often used to support the immune system and promote overall health. Research has shown that compounds derived from turkey tail mushrooms can help extend the survival times of dogs with hemangiosarcoma, a common cancer found almost exclusively in dogs.
- Wild cordyceps mushrooms, which have antifungal and antibacterial properties, as well as protein-bound polysaccharides and several amino acids. They are also known for their impressive antitumor properties.
It is important to note that while mushrooms can provide health benefits, they should not be relied upon as the sole source of nutrition for dogs. They should be given in moderation and used as part of a well-balanced diet that includes other essential nutrients. Always consult a veterinarian before introducing new foods to your dog's diet, especially if your dog has any underlying health issues or is taking medication.
