Professional dog trainer Hana Kim decided to document the challenging and adorable process of turning a puppy into a full-fledged guide dog. Shooting just one second of video a day, Kim created a moving timelapse of a puppy named Gumbo as he went through training.

In the end, it turned out Gumbo didn’t quite have the calm, unflappable personality it takes to be a guide dog, so Hana adopted the excitable pup herself. She’s now training him to be a therapy animal, which she believes is better suited to his affectionate disposition.

In Kim’s “One Second A Day—GDB Guide Dog Training,” the 10-week-old Gumbo (formerly named Lombard) goes through approximately one year of training, learning basic commands, walking with a harness, and goofing around. Over the course of the video, Gumbo grows from a tiny pup to an almost fully grown dog. Check it out above.
