A dogcart (or dog-cart) is a light horse-drawn vehicle, originally designed for sporting shooters, with a box behind the driver's seat to contain one or more retriever dogs. The dog box could be converted to a second seat. Later variants included : A young or small groom called a "tiger" might stand on a platform at the rear of a dogcart, to help or serve the driver. Frequent references to dog-carts are made by Sir Arthur Conan Doyle in his writings about fictional detective Sherlock Holmes, and indeed by many other Victorian writers, as it was a common sight in those days. * * *
