Can Dogs Eat Mushrooms?
Short answer: Plain, washed supermarket mushrooms are generally fine in small amounts, but wild mushrooms can be deadly. If your dog ate a mushroom outdoors, treat it as an emergency.
Why it’s okay
The AKC says washed supermarket mushrooms are generally fine, while wild mushrooms can be toxic. It’s often impossible to tell dangerous species apart, so any unknown mushroom should be treated as a risk.
How much and how to serve it
A small piece of plain, store-bought mushroom, with no butter, oil, garlic or onion.
Risks to watch for
- Wild mushrooms can cause serious illness and some are deadly.
- Mushrooms cooked with garlic, onion, butter or seasonings aren’t safe.
- Large amounts of any mushroom can upset the stomach.
What to do if your dog ate mushrooms
If your dog may have eaten a wild mushroom, call your vet or an emergency clinic, or the ASPCA Animal Poison Control Center at (888) 426-4435, right away. If you can, take a photo of the mushroom or bring a sample. Signs can include vomiting, drooling, weakness and tremors. Don’t wait for symptoms.
