Wild mushrooms are Serious Business
Spring in Santa Barbara can be absolutely beautiful. As warm weather follows the rains however, the fruiting mushroom population can cause the unsuspecting dog a lot of trouble. There are multiple species of mushrooms that can cause us all problems (pets and owners alike). In Santa Barbara it appears like our most troubling species of mushroom is Amanita ocreata, one of several that go by the name "Destroying Angel Mushroom". These mushrooms can cause severe liver disease resulting in death.
All "Destroying Angels" look similar and all are deadly, though it can take a mushroom expert to tell them apart. They can be solitary to scattered, usually under Coast Live Oak; I have had clients tell me they often see fruiting increase around horse manure. The only sure way to tell them apart is by examination of their spores. In general you and your pets should always avoid unknown and suspicious mushrooms. If you see a WHITE smooth cap, WHITE gills, WHITE spores, and a WHITE stalk = DANGER. Remove your pet from the area. If these are found on your property, they should be cleared daily while fruiting before your pets can gain access to them.
If you are aware your dog has eaten mushrooms, the recommended treatment is to induce vomiting when these mushrooms are ingested, and in addition give activated charcoal. Unfortunately, this ingestion is easy to miss, and our four legged friends arrive at the hospital weak, with vomiting or anorexia and diarrhea and are in liver failure. Supportive treatment for liver disease is necessary. This often involves 24 hour hospitalization for any chance of survival. An innocent looking mushroom can cause big problems, so please keep a lookout.
