David Walls, 10, was bitten on his leg yesterday when he tried to inspect a dog's tag in Blossom Park.
He went through an excruciating round of anti-rabies injections, including a shot directly into the bite wound.
Walls was set to undergo another round tomorrow, unless he could find the dog that bit him to get proof the animal was up-to-date on its shots.
David and his dad, Roger Walls walked door to door until they found the dog right in the neighborhood near Edison's Blossom Park.
Authorities tracked down the dog's owner and vet, and determined the dog was healthy.
