Lost Dog: Sprightly, Fluffy, $3K Reward!

Light brown on top, white underneath. Long soft hair but a recent haircut and a long bushy tail that waves like a flag. He's sprightly even tho he's 13, no limp or anything, capable of sprinting and running long distances still. Missing some teeth. Underbite, pushed in nose. White face fur. AFRAID OF STRANGERS, will not approach them and will flee. Had already eluded well meaning bystanders and remains at large. 3,000 dollar reward for information directly leading to me getting him back, as well as someone catching him themselves.
