And what can we do to ensure they take each step in stride? In <i>The Seven Ages of Man's Best Friend</i>, bestselling author Jan Fennell leads us through the key phases of a dog's development by uniquely defining the seven ages of our dogs: the buoyant, boundless energy of the Puppy and the Pioneer, the troublesome teens that are the ages of the Playboy and the Prot&#233;g&#233;, the difficult middle years of the Pretender and the Protector, and the twilight years of the Pensioner. The book offers advice on all the problems that crop up at particular times in a dog's development, including training and vaccinations as well as puberty and parenthood. </p> <p> In <i>The Dog Listener</i>, Jan Fennell changed the way we think about our dogs.
