WSB-TV reports Intown Healthy Hound was burglarized after closing Wednesday, and the store's owner returned to find thieves had stolen 800 bags of dog food from the shop.
James Galloway, the store's owner, told the television station the stolen food was worth about $35,000.
Police say the thieves targeted an all-natural brand that is hard to find in many pet shops across Georgia.
Authorities say the suspects cut a hole in the fence of a building next door, climbed through a window and used a forklift to load pallets of the dog food into a getaway vehicle.
Police say the store is not equipped with a surveillance camera or alarm.
