5. Shih Tzu
Known for their regal appearance and affectionate nature, Shih Tzus can live up to 16 years. Their long lifespan is often attributed to their manageable size and relatively good health. The grooming needs of a Shih Tzu, while extensive, play a role in their longevity. Regular grooming helps maintain their coat and overall health, preventing skin issues. This attention to care, coupled with their loving disposition, makes them a delightful and enduring companion for many households.
