This story breaks my heart!!!! There was recently a story in our local newspaper about a rottie who killed a sheltie that was walking on leash with his owner, right in front of his owner's eyes. A dog that I had in my childhood was killed in the same way. My dad was walking him on his leash and he was attacked by another dog running loose. The vet unfortunately was not able to pull him through. After reading the story in the paper and now hearing yours it brings back my memories too. I have to ask myself again "where were the owners of these dogs?????" I know that knowing that won't change what has happened but I just had to vent about people who let their dogs roam!! It really upsets me!!!!!! Anyway, I am sorry to say that I don't know anything really to suggest to help, but I just wanted you to know your little one will be in my thoughts and prayers. Maybe knowing that might help just a tiny bit. I hope so.
