OMG! That is horrible and I cannot imagine what you are going through again.

I don't know if you saw this information that I put together the other day but it's now a sticky. There is all kinds of information on the links on how to find a missing pup.

This second one can be used in reverse for a lost dog as well. I sure hope that you are able to find him

They say the biggest reason that dogs are not returned to their owners is because the people that find them are afraid to turn them over to the pound for fear of PTS. But that is where most people look. Hopefully if you makes the posters and follow the advice you will be reunited quickly.
