Beloved Bulldog

I will be taking our Christmas Tree down tomorrow.  It is bittersweet this year as we had to have our 13 YO English Bulldog put down because of cancer.  We have commemorative ornaments and it will be hard to put them away. We miss him terribly.  So many other sentimental ornaments on the tree also.  Do you prefer a tree with memories or do you like to be creative and decorate your tree with a theme?
