Schnoodles come in a variety of sizes just like their two parent breeds, the Schnauzer and the Poodle. Even in a single litter the size between siblings can vary greatly. The size classifications of a Schnoodle, much like its parent breeds, is based on the Schnoodle's height at the withers. The three size classifications of a Schnoodle are Standard, Miniature and Toy.
The Standard Schnoodle is a mix between the Standard Schnauzer and the Standard Poodle. The Miniature Schnoodle is greater than 15 inches at the withers. The Miniature Schnoodle is a cross of the Miniture Poodle and the Miniture Schnauzer. The Miniature Schnoodle is between 10 - 15 inches at the withers and will weigh around 11 - 16 pounds when fully grown. The Toy Schnoodle is a cross between the Miniature Schnauzer and the Toy Poodle. This Schnoodle is less than 10 inches tall at the withers and will weigh around 5 - 10 pounds.
The Schnoodle is usually bred from a Miniature Schnauzer and either a Toy or Miniature Poodle. Along with the three size classifications noted above there are also some references to Giant Schnoodles which are the cross between a Standard Poodle and a Giant Schnauzer. This is a less common cross. All of the different size variations have their own different personalities.
It is believed that a dog with Schnoodle heritage was first created in England and known as the Truffle Dogs. It is believed that Toy Poodles were crossed with small dogs from the Terrier family to create this new dog. These dogs specialized in hunting Truffles. Truffles were very valuable and gathering them often required tresspassing on others land and thus was done at night. These dogs were very helpful in locating the Truffles in the dark of the night.
The first known crossing of the Poodle and the Schnauzer in America was in the 1980s. It is believed that this first occurance of purposeful cross-breeding, to create a Schnoodle, was done in Minnesota.
While in England, Schnoodles or Schnoodle-like dogs may have been bred in the past to create dogs to help gather Truffles, but in America the modern day Schnoodle is bred purely as a companion dog. The goal of Schnoodle breeders is to create a medium sized, intelligent dog that can be owned by people with dander allergies.
The Schnoodle fad really hit its stride in the late 1990s. The popularity of the Schnoodle has grown rapidly and this mix leads the way in the Poodle Hybrid Designer Dog craze.
