Lynn....I'm sorry to hear about Dax as I know how hard it is to lose those family members.

Joanie...I had the same thing happen with an old dog who lost a litter mate. I believe he left and grieved himself to death. It's so hard not to know. I hope yours finds her way home again soon.
The world is a dangerous place to live; not because of the people who are evil, but because of the people who don't do anything about it. - Albert Einstein
