Dear Mandy,
I read your post, thank you. You did beyond at least the level best with animal intuitive-ism given the situation it seems.
The only thing I would humbly add is perhaps you did too well providing an energetic haven. With great results. When it comes up again I would suggest doing the same type thing but allowing her sense/experience of bravery to extend out further.
On a side note, it has been my experience that Reiki with animals is very strong feeling. Where as human to human Reiki packs a more subtle punch so to say.
\Namaste,
Michael
