The Fédération Cynologique Internationale (FCI) groups purebred dogs by historical function and breed standard, not by how easy they are to live with. That distinction matters: the groups are useful for understanding why a breed was developed, but they do not predict every dog’s personality.
The 10 groups
- Group 1 – Sheepdogs and cattle dogs, such as the Australian Cattle Dog. See our Red Heeler lifespan guide for a cattle dog example.
- Group 2 – Pinscher, Schnauzer, Molossoid, Swiss Mountain, and cattle dogs. Examples include Dobermans, Rottweilers, Boxers, Great Pyrenees, and Kangals.
- Group 3 – Terriers, bred for tenacity and small-game work.
- Group 4 – Dachshunds, developed for hunting underground quarry.
- Group 5 – Spitz and primitive types, including northern and ancient landraces.
- Group 6 – Scenthounds and related breeds, built to follow scent trails.
- Group 7 – Pointers and setters, bred to locate and indicate game.
- Group 8 – Retrievers, flushing dogs, and water dogs.
- Group 9 – Companion and toy dogs, selected mainly for close human life.
- Group 10 – Sighthounds, built for speed and vision.
How to use the classification
Think of the FCI groups as a map of breed purpose, not a shortcut to temperament. Working history can hint at exercise needs, trainability, and instinct, but the individual dog still matters most.

If you are trying to compare breeds, start with function first. It explains much more than appearance alone.
