10 Breeds Whose Appearance Has Hardly Changed Over The Years

#10 – Tibetan Mastiff

The ancient guard dog of Tibet is another breed that has changed little over the years. Earliest written accounts of the breed are from 1,100 BC. Tibetan Mastiffs are thought to be some of the basic stock that modern-day herding dogs are derived from. Judging by old photographs, the breed has kept an appearance similar to what they were decades ago.
