In the womb: Dogs

Using state-of-the-art visual effects and real-time 4-D ultrasound imagery, National Geographic follows the fetal development of one wolf and three different dog breeds.

From a single cell to a complex, self-sustaining organism, an infant goes through an incredible transformation before it even takes its first breath. With ground-breaking photography, computer graphics, and 4-D imaging, "In the Womb" reveals this amazing process.

"In the Womb: Dogs" will air on the National Geographic Channel on Sunday, January 4, 2009.
