One of the oldest breeds, the Pug is a family favorite due to his even temper, playful personality and outgoing, loving disposition. This charming Asian breed originated before 400 B.C. A clownish, mischievous dog, the Pug is sturdy, adaptable and trainable, making him an ideal choice for families with children. The breed needs minimal exercise. Though his short coat sheds, it requires little grooming.
