Ok, I will help.
- Turn off lock-on-af
- AF-S
- Flexible spot, small size
- "A" mode
- ISO auto
- Center weighted exposure
Point camera so that focus box is on the eye, half press to lock focus, recompose, fully press and shoot.
If this is the 16-70 or 18-105 lens, it doesn't really need stopping down, but you might try to stop it down a bit, to make the DOF is little deeper. f/5.6, or f/9 even, light permitting.
Always best to focus on the eyes. Problem with things like wide area and zone, is that it will end up focusing on whatever is closest. Lock-on-AF can totally screw up portraits! It's scan around for closer features attached to the subject. That becomes the nose in no time. Not good. So, small size flexible spot, just placed in the center, combined with AF-S, is probably best.
Another thing to look at is watch out the camera doesn't make the exposure too slow. 1/60 for a dog that won't pose still, is bad. So, perhaps instead of auto ISO, set the ISO to something, where the exposure becomes more like about the 1/250 range or so...
Another option is to use "M" mode and set ISO to auto, but that's too crude, possibly....
