The first few weeks of having a puppy are probably the most challenging. This episode shows funny and dramatic stories as the new puppies throw up a bewildering variety of challenges. Ralph, a beautiful sleek gundog, has decided that the fluffy living room rug is his toilet, and challenges the family's other, older dog mercilessly. Stan, a gentle giant rescue dog, has developed a phobia of one particular quiet country lane and refuses to go down it. Lola keeps her owners up all night by playing. Stewie, a tiny Yorkie cross, thinks he's a big dog and menaces the neighbourhood, and Byron nips repeatedly, terrorising his new family and wounding the children and their friends. As this two-part series follows the puppies through the first two months in their new homes, a trying and sometimes shocking time, the fascinating science behind their development and behaviour is explained. Why they bite and chew, why early socialisation is so crucial, and how to manage the 'fear imprint' stage.
