DeKalb Police Sgt. T.C. Medlin said Forest was so lethargic that officers thought he was dead until he lifted his head and blinked his eyes.
A second pit bull puppy had a collar embedded in its neck, Channel 2 reported.
Both dogs were confiscated by police.
Wamsley said Wednesday that Forest is getting back to a healthy weight and should be ready to be adopted as soon as vets neuter him.
Medlin said Thomas and White face up to a year in jail if convicted of the cruelty charges.
