I'm so sorry for your loss, but rest easy in the fact that she's still at home with you where she belongs. And not only is she there, but she's at the bridge pain free and happy waiting for you!
I'm glad you have her ashes. I never did this with previous dogs until I met my husband. We now have 2 cats and 1 dogs ashes on our mantel and I put them under a small Christmas tree during the holidays.
