Affleck, still wearing his wedding band, was dressed down on Monday in a blue T-shirt, zip-up hoodie, and a baseball cap, while sporting his trademark scruff.
As previously reported by Us, Garner and the kids are currently living together in a five-bedroom rental property in the Georgia city.
The puppy, meanwhile, has also been enduring the split after it was adopted this past May. As reported by Us in the June 29 issue, Affleck and Garner took their daughters to a dog adoption in the Pacific Palisades this spring, shortly before the high-profile couple announced their split in an official joint statement on June 30.
According to an eyewitness at the shelter, Affleck scowled at Garner when she encouraged their daughters to play with a litter of golden retriever puppies. The actor also was rude to a female volunteer.
"Ben was really short with her, like, 'Yeah, whatever,'" an eyewitness told Us at the time of Affleck's demeanor. Despite the tense family outing, the couple got their daughters a new puppy.
When they're not playing with the puppy, the kids have been spending time with their mom during their summer vacation. As reported, the family went to Party City on Sunday, July 19, and a pet market before they attended a pool party at a country club.
