rpicam-hello → ERROR: *** no cameras available *** (camera not enumerated)
This error indicates that the camera is not detected. Based on the image you provided, I noticed that both ends of the FPC cable are connected incorrectly — they are not plugged into the Raspberry Pi’s CAMERA interface, and the orientation is reversed. Please refer to the provided image, and you can also check the assembly video in our documentation: Assemble Videos — SunFounder PiDog Kit 1.0 documentation

libcamera-hello: command not found is normal on Bookworm because the apps have been renamed from libcamera-* to rpicam-*.

The error: bash: /home/pi/pidog/examples: Is a directory occurs because you tried to execute a directory.

Once your first issue is resolved, you can run the following commands:
cd ~/pidog/examples
sudo python3 7_face_track.py
