City of Dawsonville officials are investigating the report by a local postal worker, who said he was bitten by a dog while on his route last week in the Burt's Crossing subdivision. City Manager David Headley said his office was made aware of the Jan. 11 incident on Thursday and the dog was placed in quarantine for 10 days on Friday, as required by city ordinance "We have contacted the health department and are filing the required paperwork," he said. Headley described the bite as "minimal" and does not classify the Australian Shepherd as vicious.
