Mushrooms in the Lawn: No Spray Exists; Remove for Dog Safety

Why No Chemical Control

Mushrooms are fruiting bodies of fungi decomposing underground organic matter (roots, thatch). Only removing the organic substrate (replace with sand/gravel) eliminates them.

Dog Safety

While few mushrooms are toxic, ASPCA advises caution. Liver damage possible. Remove mushrooms when dog isn't watching—dogs investigate spots you've touched.

Symptoms of Poisoning

Pale gums, lethargy. Seek vet immediately if ingestion suspected.
