How many types of Feists are there?
The question of how many types of Feists there are is a bit complicated and depends on who you ask or what organization you consult. The American Kennel Club (AKC) currently does not recognize any Feist breeds. The Continental Kennel Club (CKC) and the United Kennel Club (UKC) recognize the Treeing Feist and the Mountain Feist as separate and legitimate breeds. 
While the Treeing Feist and the Mountain Feist are the only two Feist breeds recognized by any major kennel clubs, there are many more unregistered types described and developed by enthusiasts of the breed, including the Denmark Feist, Mullins Feist, Charlie Feist, Buckley Mountain Feist, Kemmer Feist, and Barger Stock Feist. These various types come from distinct lineages but don’t yet meet the requirements to be considered separate breeds by any major kennel clubs.
