An initial X-ray found a screw lodged inside Jupiter's stomach - potentially deadly if, like some, the screw contained zinc.
At the very least, the errant object could cause untold carnage to Jupiter's digestive tract.
But a subsequent probe found no sign of the screw, suggesting it might have tumbled into his intestines.
Somewhere along the way, however, the group found Jupiter's spirit, which apparently hadn't completely checked out.
Brooks says Jupiter is friendly with humans and other dogs. And, most importantly, he's now in stable condition.
