Dachshunds are a small dog with a long body and short legs, sometimes called a sausage dog. Some people say that a dachshund is "two dogs long and half a dog high". They are the shape they are because they were bred to hunt animals that live down burrows, such as badgers and rabbits. Dachshunds come in a variety of colours, and can have long or short hair.
