The AKC notes washed, store-bought mushrooms are generally fine, but avoid mushrooms cooked with butter, garlic or onion. Wild mushrooms are hard to identify, and species such as death caps can cause fatal liver failure, with signs delayed for 6 to 24 hours.

Can Dogs Eat Mushrooms?

Yes, in moderation
Plain, store-bought mushrooms are generally fine for dogs in small amounts. Wild mushrooms are a different matter: some are deadly. If your dog ate a mushroom in the garden or on a walk, call your vet or a poison line straight away.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
What you need to know
How to offer it safely
- Offer plain, cooked or raw store-bought mushrooms only.
- Never share mushrooms cooked with garlic, onion or heavy butter.
- Check your garden and walk routes for wild mushrooms, especially in autumn.
Treats, including human food, should make up no more than about 10% of your dog's daily calories. Our calorie calculator shows your dog's daily needs. Introduce any new food slowly and stop if it causes vomiting or loose stools.
If your dog ate some
- Wild mushrooms: treat as an emergency even if your dog seems fine.
- Take a photo, or a sample in a paper bag, to help identification.
Signs to watch for
- Vomiting and diarrhoea
- Drooling
- Wobbliness, tremors or seizures
- Yellow gums or eyes (liver damage), sometimes a day or more later
Collapse, seizures, difficulty breathing or pale gums are emergencies: go to the nearest vet straight away.

How quickly do mushroom poisoning signs start?
Some cause signs within hours; the most dangerous types may not cause signs for 6 to 24 hours, by which time the liver is already damaged.
