Mushrooms are a fun snack for dogs, but it's important to be cautious. While store-bought mushrooms like portobello, white button, cremini, and shiitake mushrooms are generally safe for dogs to eat, it's best to avoid wild mushrooms as they can be toxic and even deadly. If your dog consumes a wild mushroom, contact your veterinarian immediately. Even if your dog eats a store-bought mushroom, it's important to watch for any signs of an allergic reaction or gastrointestinal upset. Mushrooms should be given in small amounts as they don't offer many nutritional benefits to dogs and are not a necessary part of their diet.

What You'll Learn

Store-bought mushrooms are generally safe for dogs
Dogs should never eat raw or cooked wild mushrooms as these can be toxic and even deadly. If your dog consumes a wild mushroom, contact your veterinarian or animal poison control immediately. It is also important to keep your dog away from areas where wild mushrooms grow and to train them to "leave it" when commanded to prevent them from eating wild mushrooms.
Some common store-bought mushrooms that are safe for dogs to eat in moderation include white button mushrooms, cremini mushrooms, portobello mushrooms, baby bella mushrooms, shiitake mushrooms, and oyster mushrooms. These mushrooms can be fed to dogs either cooked or raw, although cooking them may be better for your dog's digestion.
It is always a good idea to consult your veterinarian before feeding your dog any new foods, especially if your dog has any allergies or health conditions. Additionally, if you are unsure whether a mushroom is safe for your dog to eat, it is better to be cautious and avoid feeding it to them.

Wild mushrooms are toxic and dangerous for dogs
Store-bought mushrooms are generally safe for dogs to eat. However, wild mushrooms can be toxic and dangerous for dogs. While only a small percentage of the mushroom species in the world are toxic, the ones that are toxic are extremely dangerous and can be deadly. It can be difficult to distinguish toxic mushrooms from non-toxic mushrooms, and even practiced mushroom foragers make mistakes in identification. Therefore, veterinarians recommend treating all wild mushrooms as potentially toxic and seeking immediate veterinary care if your dog ingests one.
There are many different species of mushrooms, and they can cause a variety of toxic reactions. Some wild mushrooms that seem to cause the most problems include Amanita phalloides, commonly known as "death cap", Galerina marginata, known as "deadly Galerina" or "Galerina autumnalis", Inocybe spp., and Clitocybe dealbata mushrooms. These toxic mushrooms can have a fishy odour, which dogs find particularly attractive, and may explain why pets commonly ingest these species.
The symptoms of mushroom poisoning in dogs depend on the species of mushroom and the amount ingested. Certain mushroom species contain different toxins, which affect dogs differently. Common clinical signs of mushroom poisoning include gastrointestinal issues such as vomiting and diarrhea, neurologic and hallucinogenic effects such as stumbling and seizures, and kidney failure. In some cases, there may be a false recovery period where the dog seems to feel better, followed by liver failure, acute kidney injury, and death.
If your dog has ingested a wild mushroom, it is important to contact your veterinarian, animal poison control centre, or emergency veterinary hospital immediately. If possible, bring a sample of the mushroom, preferably wrapped in a damp paper towel and stored in a paper bag, to help with identification and treatment. The sooner your dog receives veterinary attention, the better.

Symptoms of mushroom poisoning in dogs
Store-bought mushrooms are generally safe for dogs to eat. However, wild mushrooms can be toxic and even deadly. If your dog has ingested a wild mushroom, you should contact your veterinarian immediately. If you are able to, bring a sample of the mushroom to the clinic so that the veterinarian will know how to treat your dog.
Now, here is some information on the symptoms of mushroom poisoning in dogs.
Mushroom poisoning in dogs must be treated as a medical emergency, no matter which mushroom your dog ate. The severity of mushroom-induced illness depends on the type and number of mushrooms ingested. Some dogs may be treated outpatient, with symptomatic care for vomiting and diarrhea. However, if the mushroom is highly toxic, your dog will need to be hospitalized and started on IV fluids for hydration and supportive care.
Common clinical signs of mushroom poisoning in dogs include vomiting, diarrhea, abdominal pain, tremors, and seizures. In addition, symptoms of mushroom poisoning can also include nausea, drowsiness, twitching, and paralysis. It is important to note that symptoms can vary depending on the size, age, and metabolism of your dog.
The deadliest type of mushroom is the Amanita species, also known as the "death cap" or "death angel." These mushrooms cause liver failure, which can be deadly. Symptoms of liver failure include jaundice, weakness, lethargy, and coma. It is important to seek immediate veterinary care if you suspect your dog has ingested any type of mushroom, as prompt treatment is critical to a successful outcome.

Safe dosage of store-bought mushrooms for dogs
Store-bought mushrooms are generally safe for dogs to eat. However, it is important to ensure that they are cooked without any additional ingredients that may be harmful to dogs, such as garlic, onions, salt, spices, or oils. Mushrooms contain a tough, chitinous wall that holds the nutrients, and cooking breaks this wall down, making the nutrients available to dogs. Cooking also inactivates monomethyl hydrazine, a substance that can be toxic in raw mushrooms.
It is recommended that treats make up only 10% of a dog's daily caloric intake. In addition, it is important to consult a veterinarian before feeding a dog any new foods, as what is suitable for one dog may not be appropriate for another, depending on factors such as age, health history, health conditions, and diet. Dogs on prescription diets should not be fed any food or treats outside of their prescribed diet.
Some sources suggest that medicinal mushrooms in dried form can be used to make a broth, which can be given to dogs at a rate of 0.5 ml per 5 lbs of body weight. However, it is important to note that the dosage on the package should be followed if the product is specifically for dogs. If the product is packaged for humans, it is recommended to assume the dosage is for a 150-pound person and adjust accordingly for the dog's weight, starting with a lower dose to avoid any potential digestive issues.
It is important to note that while store-bought mushrooms are generally safe, wild mushrooms can be extremely dangerous for dogs, even deadly. If a dog consumes a wild mushroom, it is important to contact a veterinarian or pet poison control immediately, as even expert foragers can struggle to identify certain species.

Nutritional benefits of mushrooms for dogs
Store-bought mushrooms are generally safe for dogs to eat, and they can even offer some nutritional benefits. However, it's important to note that mushrooms don't provide many health benefits for dogs, and there are more nutritious treats you can give them. Mushrooms should be given as an occasional treat, with treats making up only 10% of your dog's daily caloric intake.
Mushrooms are a good source of vitamins, minerals, fibre, protein, iron, and magnesium. They also contain vitamins A, B, C, D, and E. Some mushroom species, such as shiitake or maitake mushrooms, are particularly nutrient-rich. These mushrooms contain B vitamins, vitamin D, potassium, copper, and selenium.
Mushrooms are also a source of both soluble and insoluble dietary fibre, which can support digestive health in dogs. Adequate fibre intake helps regulate bowel movements, maintain healthy gut bacteria, and prevent constipation.
In addition to their nutritional benefits, medicinal mushrooms have gained popularity for their potential health benefits. Some mushroom varieties, like Reishi, Turkey Tail, and Chaga mushrooms, are known for their potential immune-boosting, anti-inflammatory, and health-promoting properties. For example, Turkey Tail mushrooms have been shown to help treat certain cancers and decrease inflammation in the urinary and digestive tracts.
However, it's important to consult a qualified veterinarian before feeding your dog mushrooms, as they can be toxic to dogs in some cases. Wild mushrooms, in particular, can be highly toxic and even deadly. Even some store-bought mushrooms can be harmful if they are cooked with ingredients that are toxic to dogs, such as garlic or onions.
