Oooh,,,I am only seeing this now, so late -- I just want to send you heaps of sympathy and commiseration. What a gorgeous tribute you have written for her and what beautiful photos -- they illustrate the rich and loving bond you shared.
Brooklyn sounds a little bit like my friend Danielle's dog, with whom I hike almost every weekend. Also a rescue with one failed adoption behind her, I believe, also abundantly energetic and in need of someone who could give her dedicated guidance and constant exercise and something to stimulate her big brain.
Wishing you strength as you grieve. It is so, so hard to lose our beloved animal friends.
