So sorry to hear this.

Anna, sweet girl
Blue eyes so deep and wise
Fur so lush and heart so strong
Majestic and cuddly all in one body
Rest now, and then play
Reunited with loved ones at The Rainbow Bridge
And together you can wait, healthy again
Until that shining someday distant day
When you and your people will be
United again

Send them love, in blue skies and grey clouds
Let them know you are watching
Send kisses in their dreams
Rest in peace, Anna, dear, rest in peace.
