Tanya:

When my second Golden died, I also had her ashes returned to me in a marble urn. I buried the urn in my backyard and planted a shrub over it. I thought it was a good way to have a memorial for her and every Spring, when the yellow flowers appear, they are a cheerful reminder of the happy times we had together. Perhaps you could do something like that for Rocky.
It's very sad to loose a dog, I know, but it's even worse to live without one.
