MetalPoki,
I have merged your three threads into one, as all three are related to the same topic. Opening multiple threads simply adds to confusion for you and those replying to your requests for help.
Question: Have you called MPSJ to ask about the dog's tag number? If you do so, will they give you the owner's contact information? Just a thought... I don't really know how MPSJ works. Also, contacting vet clinics in your area might be helpful, as many people turn to their vets when dogs go missing. Good luck either finding his owners or a temporary fosterer!
