Thanks everyone!
You know, sometimes I really thought I was just putting my own human emotions about Linus on to Truman. Animals are so much more resilient than humans, I think! But once we received this stone, I, for the life of me, could not figure out why he would just lay near it - away from us, away from the television, just with the stone. Then he started putting his paws on it and sleeping and I am totally convinced there is something special around it that he can feel. I know it sounds wacky but what other explanation is there?
[MENTION=572]Libra926[/MENTION] To answer your question, I have slowly started the process of cleaning and removing some of Linus' things. When the baby came and we had company in town, I finally washed and moved his dog bed. To that point, I had it in the living room with a stuffed bulldog in it. (Weird, I know!) I have a box of toys that he used in my living room still and I haven't moved those yet. Truman doesn't express a strong interest in those items, even though they smell like Linus still (I assume)...just the stone. He guards it like a sentinel.
We are planning on having our yard landscaped in the spring and will be placing it outside under a tree we'll plant in Linus' memory.
