Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Plain, shop-bought mushrooms (button, cremini, portobello, shiitake) that are safe for humans are also safe for dogs when cooked without garlic, onions, butter, or other seasoning. However, wild mushrooms can be extremely dangerous — some species cause liver failure, seizures, and death. Since identifying toxic mushroom species is difficult even for experts, never let your dog eat wild mushrooms found in gardens, parks, or woods. If your dog eats a wild mushroom, treat it as a potential emergency and contact your vet immediately. Try to bring a sample of the mushroom for identification.
What You Should Know
While mushrooms is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
