ROCHESTER HILLS, MICH. -- A Jack Russell terrier is heading home to Tennessee after turning up about 500 miles away in a Michigan backyard.

The Michigan Humane Society says someone recently found Petey in the Detroit suburb of Rochester Hills. During their examination of Petey, the Humane Society found a microchip that matched the 4-year-old dog to owner Jim Arrighi, in Erin, Tenn.

Petey had been missing since July, and it's not known how he ended up in Michigan.
A Humane Society volunteer was planning to drive Petey home on Wednesday.
