In this episode, we meet chihuahua Chloe, setting up residence in a London nail salon. She wants to befriend ten-year-old Rocky, formerly top dog in the household, but Rocky is not interested. Border collie Jura joins a ski patroller in the Scottish highlands, where owner Will wants to train her to become the Nevis range's first avalanche search and rescue dog. Rescue pup Pedro is brought from Spain to spend his life in the genteel surroundings of the Surrey countryside. And golden retriever Lola joins the Paye family, where mum and dad have been persuaded to get a dog by their children, on the agreement that they will do all the hard work.
