ROCHESTER HILLS, Mich. (AP) - 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.
