Alice Chambers was a frontier prostitute who worked in Dodge City, Kansas, and other towns in the nineteenth century American West. Chambers was knicknamed Squirrel Tooth Alice because she was frequently seen (and even photographed) with her pet Prairie dog, which many people mistook to be a squirrel. It is the photograph of Alice Chambers with her pet prairie dog that makes her famous. Wikipedia
