Soon after I lost my two dogs Crystal and Spike I got Brooklyn. Sometimes she would bark into the empty corner where Crystal used to sleep. It used to scare me to death
. Now if she does it, I say hello to my babies over the bridge and tell them I love and miss them. Might not be anything, but it makes ME feel better.
Edited to add: she hasn't barked into the empty corner in a long time now that I think of it. Hmmm....
