When we had Rudy and Delaney cremated - after 1 month we scattered the ashes in their lot - in the places they both loved to either sit or run. It was a nice, but teary celebration when we let their ashes go free.
We have the little urns on our bookshelf. I never wanted to keep their ashes in the urns. It is kind of like they are out there still, a bit over 2 years for Rudy, and almost 2 years for Delaney.
A dog is the only thing on earth that loves you more than he loves himself.
