aspca.orgWhy Mushrooms Can Fit This Verdict
Can dogs eat mushrooms? Ask your vet first: plain store-bought mushrooms may be tolerated by some dogs, but wild, yard, or unidentified mushrooms should be treated as dangerous. Avoid mushrooms cooked with garlic, onion, butter, wine, or salt, and call a veterinarian or pet poison control if your dog ate an unknown mushroom.
How Much Mushrooms Can Dogs Eat?
Do not use mushrooms as a routine treat. If your veterinarian says plain store-bought mushrooms fit your dog, a small dog should get only a tiny chopped piece and a large dog only a few small plain pieces; wild, unknown, or unidentified mushrooms should not be fed at all.
How to Serve Mushrooms Safely
Only consider washed, store-bought, plain cooked mushrooms with no butter, oil, salt, garlic, onion, wine, cream sauce, or seasoning. Avoid wild mushrooms, yard mushrooms, foraged mushrooms, garlic butter mushrooms, canned salty mushrooms, mushroom gravy, and mixed restaurant dishes. Portabella mushrooms is a common spelling for portobello mushrooms; either way, only consider store-bought plain cooked pieces if your veterinarian approves.
What to Watch For
Mushroom-specific warning signs can include vomiting, diarrhea, drooling, wobbliness, tremors, weakness, belly pain, yellowing gums or eyes, seizures, or collapse after an unknown mushroom. Store-bought plain mushroom stomach upset is different from possible wild mushroom poisoning.
When to Call a Vet
Monitor only if your dog ate a tiny amount of known plain store-bought mushroom. Call your vet or pet poison control immediately for wild mushrooms, yard mushrooms, unknown mushroom pieces, garlic butter mushrooms, canned salty mushrooms, or any neurologic signs, repeated vomiting, weakness, or collapse.
Common Mistakes
- Treating wild mushrooms like grocery-store mushrooms.
- Waiting for symptoms after a dog ate a yard mushroom.
- Serving garlic butter mushrooms or mushrooms cooked with onion.
- Using canned mushrooms without checking sodium and added ingredients.
- Assuming a mushroom is safe because a person can identify it casually.
- Forgetting to take a photo or sample of an unknown mushroom for professional guidance.
