My heart goes out to you,your family and her.
I grew up with dogs always in my life, and I have 2 dogs now. It is so hard and heart breaking to say "goodbye" . . .I know, yes I know way too well. Try to sit on the other side (though very hard) and realize this wonderful creation, has been able to know love,affection and care. She loves you and always will, . . . even in the "other" world.
Just, believe, just believe . . .

All my love and condolescences,
Rosanne
