This is an Italian sheepherding breed who takes his name from his hometown, Bergamo (although he is also known in other parts of the country). He is similar to other central European sheepdog breeds, including the Puli which shares his heavily matted coat.
After World War II, the Bergamasco was in danger of disappearing because there was less work for herding dogs. Fortunately, an Italian breeder, Dr. Maria Andreoli, stepped in and led the effort to save the breed.
The Bergamasco has not yet achieved full recognition from the American Kennel Club but is biding his time in the Miscellaneous Class.
