The image was the first of Woods since he suffered serious right leg injuries in a one-car crash February 23 near Los Angeles.
Two months later, the 15-time major winner appeared alongside his dog in the image, taken in his home practice facility in Jupiter, Florida.
Woods said that work was progressing faster upon his three-hole backyard practice course than he was progressing in his recovery.
“My course is coming along faster than I am,” Woods wrote. “But it’s nice to have a faithful rehab partner, man’s best friend.”
Woods, 45, has won 82 US PGA Tour titles, level with Sam Snead for the all-time record.
Before Woods was injured in the crash, he was working to overcome a back operation in time to play at the Masters earlier this month.
Woods has released no timetable regarding how extensive his injuries are or when he might walk normally again, much less return to his golfing career.
Police found Woods was driving nearly twice the legal speed limit when his SUV went out of control and rolled several times before stopping.
Woods was hospitalized for weeks before returning home to Florida last month.
He underwent hours of surgery to repair a shattered lower right leg and ankle, including the insertion of a rod into his tibia and screws and pins being used to stabilize his ankle.
Woods had undergone a series of back operations before making a fairytale comeback that saw him win the 2019 Masters for his first major title since the 2008 US Open at Torrey Pines.
