Folks first spotted the pup, now known as Fern, last month near the intersection of Kanis Rd. and Ferndale Cutoff.
There's a hole on top of the water jug, so the dog can still drink and eat.
But, animal rescue volunteers haven't seen Fern in a couple of weeks and fear she could be injured.
If you spot the dog, you're asked to call the Pulaski County Sheriff's Office.
