Hmmm, I seem to be having a brain cramp day cuz I still don't get the connection between your question and the clarification.

But why let a little thing like that stop me from talking about dogs, one of my favourite topics?!
;-)
You were correct that the two phrases are linked, at least to the extent that my frequent choice to take those remote walks rather than local "busy" walks, (bike-busy, skateboard-busy, jogger-busy etc.) contributed to insufficient quantity of good socialization opportunities, especially in the 4.5-6 month window, and even up to 10 or 12 months, which is still a far easier time for it than after the brain has fully matured. Add that to my giving him insufficient boundaries and it is no great mystery that when he hit the "teen months" his boundary testing was exaggerated.

The greater mystery, looking back, is that I made such rookie mistakes even though I had successfully socialized 3 dogs as puppies and re-socialized a 16 months old rescue. Shoulda known better...
