Help Us Track Coyotes with Mange in Marin

See a coyote with mange? Report it.

Seeing a coyote sick with mange is heartbreaking. There's no official way to help just yet, but solutions take time—and every sighting brings us closer to change.

⚠️ Please Do Not Treat Coyotes Yourself

Medications meant for pets can cause seizures or death in wildlife at the wrong dose. If two people unknowingly medicate the same coyote, it can be fatal.

Photos or Video

Photos are one of the most powerful tools we have for identifying individual coyotes across sightings — but don't let a missing photo stop you from reporting. Every sighting matters.

Report Received

Thank You

Thank you for taking the time to report what you've seen. What you see and report are the first steps toward any meaningful change. Keep watching, keep reporting. Every sighting matters.

What you can do next

The most powerful thing you can do next? Tell a neighbor about rat poison.

Nearly all coyotes suffering from mange have been exposed to these poisons through the food chain. California bans consumer sales — but pest control companies still use them freely, and most neighbors don't know the connection to the sick coyotes they're seeing.
