Save Onyx

Onyx was rehomes last year because I though he would be happier in a home with less noise and stress. He's a wonderful dog but nervous by nature. His family was supposed to return him or let me know if they couldn't keep him for any reason, and that I would take him back. Sadly this morning I received a phone call from animal control in AZ, that he has been turned in as a stray. Im trying to gather funds to pay his 312 + 31$ a day pound fee and then air fair to have him flown back to Illinois. Any help is very much appreciated.
