Set A3 to Delay, not Quick

What value did you have for Custom Setting A3?

I shot that on 3, in the middle. I have since changed it to 1, Quick.

You should set A3 to more Delay, not quicker. This value tells the camera how quickly to pick a new subject. And what you wrote above was:

The square sometimes locked onto an object in the background, or halfway in the doggie's run, it would decide the dog is no longer the subject, and start jumping elsewhere in the frame. Then focus was lost.

This is textbook symptoms of a3 being set too fast.

It's unfortunate that so many set (& suggest setting) this to quicker, which is usually the wrong value for what one is trying to achieve. I suspect people see the word "Quick" and think "This will make my focus quicker." But that is not the case.

Setting A3 just makes your camera's subject tracking more erratic. This setting means: "How quickly do you want the camera to forget your subject?"

As I wrote in that link and above, set it to 4 or 5. Delayed keeps your intended subject in focus longer. This is even specified in the manual:
