I am so sorry to read about Pixie. Your story is closely aligned to mine. Sophie was with me for 13 years, by my side through two ovarian cancer surgeries, hip replacement and many life changes. Always there, she was my constant.
Poor little Pixie's little heart just gave out and it sounds like she tried very hard to gain strength. As with Sophie, her little body was just tired and I helped her cross the bridge in January '07.
I am sending you a link that I received after Sophie's death because I was also devastated. It has been a year, and I still fall apart thinking about her.
Bless you and continue with Yorkie Talk because this forum helped me heal. Let us be your refuge.
Warmly, Deborah
