#18 MINIATURE SCHNAUZER
The first of many breeds on this list originating in Germany, the Miniature Schnauzer was bred from the standard size Schnauzer for the purpose of catching rats. They’re said to make great guard dogs with more bark than bite and typically come in all black, salt and pepper, or a black and silver coat.
One of the newer breeds on this list, the Miniature Schnauzer wasn’t recognized by the American Kennel Club until 1926 – just two years after the breed was brought to the United States. This miniature version typically doesn’t surpass 15 pounds and has a lifespan of about 14 years.
