What to do
This is specifically a horse hazard, most dangerous with wilted or dried leaves (as after a fallen branch or in autumn leaf litter) — fresh leaves on a healthy tree are much lower risk. Not established as a dog or cat toxin.
Toxic component and mechanism
The toxic component in Carolina Maple is gallic acid derivatives (cause oxidative red blood cell damage, primarily documented in horses).
What makes this plant different
Carolina Maple is simply a regional common name for Red Maple (Acer rubrum) — the same wilted-leaf-specific hemolytic anemia risk in horses applies regardless of which name is used locally.
