Only spotted this now... I remember reading Tigger's forever mum's article and found it very emotional. I'm so sorry to hear Tigger, like so many of the best dogs, didn't get to see the year out. I'm sure he would have missed out on some special times if he hadn't been given a second chance there... lucky dog having had that much love in his life.
I call animals "guardians of Being," especially animals that live with humans. Because, for many humans, it's through their contact with animals they get in touch with that level of being. Eckhart Tolle
