Lecture Notes

The transition period takes place when the puppy is 14 to 21 days old. It is a period of rapid change. The puppy goes from a condition of complete dependence on its mother to one of relative independence. Auditory evoked startle response begins at 18 days and the puppy begins to localize sound. The sensory organs and neurological system are maturing. So it's important to think about the huge increase of information that the puppy is processing right now.
