Documentary charting the first few months of a dog's life, following different breeds as they take the first steps on their own unique developmental journey. Dalmatians Daphne and Digby start to develop the spots that will mark them out for life, and take their first stumbling steps in the great outdoors. Ruby the toy poodle's huge personality belies her diminutive frame, while abandoned Jack Russell pup Boomer's shattered confidence will need to be rebuilt by the love of a foster home.

The documentary explores how dogs learn to communicate with each other, and their owners. While barking might seem like the most obvious way dogs can `speak', canines communicate far more frequently with their ears, eyes, tail and snout, in accordance with a strict code of behaviour. Here, future show-dog Ace - a five-week-old corgi - demonstrates an impressive array of yelps, growls, leaps and squeaks, and pointer Molly begins elementary training with her owner, but struggles to grasp whether human gestures and commands are being addressed to her.
