HELP! The Rescue Has MY DOG! =(

I am going crazy... I have been searching for my JRT for over a week and last night I finally got a good lead on someone who had him and after following his tracks I found out he has very likely landed in your JRTRescue... The shelter, whom I HAD previously spoke with, had no recollection of him that placed him in it doesn't open for another 2 hours and I need to find something out ASAP. I am so sick... Please help me.. how will I get my dog back if he has entered into the program? I am desperate for my Tuffy back.. I am grateful that your program exists though.. as I learned he would be dead if he were NOT A JRT. =,( Please help me.
