Yes, someday the troll will die...and it will probably still be a lonesome, pathetic social misfit with no real name, no identity, and no one to miss it or be sorry to see it go...really kinda sad, when you think about it..
I Know how you feel lilly, but knowing how much you love your dogs, I know for the time she was here she was in the best place she could be, somehow that has always helped me with loved ones I've lost and also I feel like they are still with us in spirit. you were a great mom to her so feel good about that!
Sorry to hear that, Lilly... But think of it this way: the puppy is happily bouncing around in some other dimension. She gave you joy, and that'll stay with you always.
