The zoo's senior veterinarian described the cub's first tentative steps "like a toddler holding onto the furniture."
Zoo officials say the panda's physical development is on track for its age and within a few months, the cub should be mobile enough to explore the panda exhibit. For now, he is starting to stand up on all four paws and working on his balance.
At the Thursday exam, the cub came weighed in at 7.2 pounds and measured 21.6 inches long. Also, the cub is beginning to develop a spot on his tail.
The baby was born July 29. The zoo will announce the panda's name in November once he is 100 days old, which is a Chinese tradition.
