AKC Foundation Stock Service (FSS): The FSS recognizes breeds not yet accepted into the AKC, but gaining popularity and meeting certain requirements. There are several breeds in this category, but the list is subject to change.
Beyond AKC:
* United Kennel Club (UKC): This organization recognizes breeds not in the AKC list.
* International Canine Federation (FCI): An international federation with various breed standards.
* Breed-specific clubs: Some breeds have dedicated clubs that maintain their own standards.
Mixes:
* Designer dogs: These are intentional mixes of two specific breeds (e.g., Labradoodle, Cockapoo).
* Mixed breeds: These are dogs whose lineage is unknown or mixed from various breeds.
This is just a starting point! The world of dog breeds is vast and constantly evolving. Always research the specific breed or mix you're interested in before making any decisions.
