Miniature Schnauzer ( also known as Mini Schnauzer) is the smallest breed of the Schnauzer type that originated in Germany in the mid to late 1800. Other Schnauzer breeds include Standard Schnauzer and Giant Schnauzer. Of the three types, a Miniature Schnauzer is the most popular breed due to its small size and temperament. These dogs are regarded as non-shedding dogs which is not entirely true. They shed at minimal levels. However, the shed hair is trapped by the wiry outer coat. For this reason, they are considered hypoallergenic. In North America, Mini Schnauzer is categorized in the Terrier Group due its ratting background. Although, it doesn't share common ancestry with Terriers from Great Britain. When compared to Terriers, Mini Schnauzers have a more laid back personality and less aggressive to other dogs.
