What is earthdog?
Straight from the AKC:
The purpose of non-competitive Earthdog tests is to offer breeders and owners of small Terriers and Dachshunds a standardized gauge to measure their dogs’ natural aptitude and trained hunting and working behaviors when exposed to an underground hunting situation. The noncompetitive program begins with a basic introduction to den work and quarry and progresses through gradual steps to require the dog to demonstrate that it is willing to perform the required tasks including seeking its quarry, locating and working it underground.
