There is absolutely nothing in focus here.

What does this mean?
Contrast Detect AF In Focus: No

and

Depth Of Field : 2.42 m (4.66 - 7.09)
Field Of View : 25.8 deg (2.57 m)
Focal Length : 52.0 mm (35 mm equivalent: 78.0 mm)
Hyperfocal Distance : 27.00 m

Meaning 13M to 17M where in focus,
but the dog was only 1.5M away,
