> foxtail grass

ah yeah we call this spear grass locally (and probably also foxtail) and never read what it can do. (spoiler below)

they can burrow their way into the bloodstream and travel down to the heart & lungs. So incredibly dangerous for something so pervasive and normal.

Super cool writeup! The helmet cam at the end was gravy.

Wherever the OP is, this feels very much like the kind of thing your local veterinary school extension office can connect you with someone to help with.
