Warum?

While grocery-store mushrooms (Agaricus bisporus — button, cremini, portobello) are safe for dogs, wild mushrooms are a different matter entirely. Approximately 20 species of wild mushrooms are lethal to dogs and humans, and they are difficult to identify reliably even for experts.

Amanita phalloides (death cap) and Amanita ocreata (death angel) contain amatoxins that shut down liver and kidney function. The insidious pattern: GI symptoms appear in the first 6–24 hours, then resolve, making owners believe the dog has recovered — while amatoxin silently destroys liver cells. Liver failure becomes apparent 24–96 hours after ingestion, often too late for effective intervention.

Other toxic genera include Galerina (amatoxins), Gyromitra (gyromitrin, converted to monomethylhydrazine in the body), and Cortinarius (orellanine, causes kidney failure weeks later).

Welche Menge ist gefährlich?

A single death cap mushroom contains enough amatoxin to be fatal for a dog or a child.

Was soll ich tun?

If your dog ate any wild mushroom, treat it as an emergency even if the dog seems fine. Try to collect or photograph the mushroom if you can do so safely. Contact your vet or ASPCA Poison Control (+1 888-426-4435) immediately.

Häufige Fragen

Are store-bought mushrooms safe for dogs?

Yes. White button, cremini, portobello, oyster, and shiitake mushrooms (from the grocery store) are safe for dogs. The danger is wild-foraged varieties.

How do I know if a mushroom in my yard is toxic?

You often cannot reliably identify mushrooms without expert mycological knowledge. The safest approach: remove any mushrooms from your yard before they can be found by your dog.
