Pizza Dough problems, diagnosed

Pizza dough tears when the gluten is too weak, the dough is too tight and being forced, it is still too cold, it has overproofed and weakened, or one spot is being stretched much thinner than the rest.

Pizza dough that will not rise is usually too cold, made with weak yeast, exposed to overly hot mixing water, too stiff from excess flour, or slowed by a major salt or sugar imbalance.
