What makes it harmful
juglone (mild); the bigger risks are the very high fat content and aflatoxin mold that grows on stored pecans
What to do if eaten
If many pecans — especially moldy ones — are eaten, watch for vomiting or belly pain and call a vet.
How to serve safely
ASPCA lists pecans on its “foods to avoid.” The high oil/fat content triggers vomiting, diarrhea, and pancreatitis, and moldy pecans can carry aflatoxins. A single dropped nut is usually harmless, but don’t offer them as a treat.
