Oh my goodness, this is so sad. I’m sorry you lost your Edee. Please don’t let your sadness stop you from getting another dog. You will never replace Edee. There will always be a tiny hole and special place in your heart for her, but loving another dog certainly helps the heart heal. Big hugs to you from our doggy household.
I think they should be looking at Flo as the suspect in this foul play.
