Why is a naturally reserved Croatian Sheepdog unlikely to be receptive to advanced obedience training if socialization is neglected?

Anxiety or fear shuts down the learning centers of the brain.

If a dog is anxious or fearful due to lack of exposure to new stimuli, stress inhibits their ability to learn and be receptive to training commands.
