I'm praying that you find your baby soon. This link may be helpful. Have you filled out lost pet forms at the shelters? Make sure to include a photo of her. And visit them every few days. Do not rely on them to call you if they think they have her. Go there and look at every cat. Ask if they have cats mixed with the dogs or in the infirmary. Look through the found pet forms to see if any were found close to you. And as awful as it is, ask to look through the DOA file. If the worst has happened, at least you'll know instead of always wonder.
