Thank you all for your answers and concern.

I have emailed posters to all the refuges and call them to confirm theyhave them, same with local vets and the police.

We have also put posters absolutely everywhere in the Entremont area, including all the walking paths. We have also spread the word via facebook as much as we have been able, we have good friends over here that have been walking the mountains looking for her.

Thank you for your advice Melloncollie, I have changed the picture in STMZ, I am trying to remember the login details for the Tierdatenbank to change it too.

My husband is out again now looking for her, let's hope he comes back with good news.
It is not normal for Roxy to disappeared like that, although she likes chasing marmots and rabits
Thank you
