At this distance from the subject, the depth of field is too shallow (your camera is at F3.2 its most wide-open setting) that only part of the dog will be in focus.
Additionally, the camera is set to be so sensitive (iso 1600) that you will be getting noisy pictures. There is a distinct color cast, see the magenta shadows on the white background.
You would be better off taking the pictures in a more natural setting (no completely white background), at the dog's eye level, not using the on-board flash, moving further away, setting the ISO to 200 or 400.
