Found a scared and injured dog right front leg looked strange. The poor dog was just running heading to the forges, I tried to catch it but it wouldn’t come near me so worried about it

Espérons qu'il soit vite mis en sécurité avec eau et nourriture ce pauvre loulou. Voir s'il peut y avoir un signalement en mairie ou sur un site parmi les perdus et laissez lui à distance de quoi boire et manger. Merci pour lui, en danger et en souffrance à rester errant.

Thank you for your report.
Sadly, this is almost certainly a poor dog exploited for hunting that has either gotten lost or been abandoned.

WHAT YOU MUST DO: notify the town hall of the municipality concerned.
Mayors are legally responsible for stray animals within their jurisdiction—whether injured or not—and are required to arrange for their care and handling (Articles L211-21 and L211-22 of the CRPM).

Please be sure to follow the advice from Azur above, and thank you for keeping us updated.
