Dog Breed - Genetics

Genetics

Dog breeds can now be analyzed through genetics. Genetic markers (microsatellite markers and single-nucleotide polymorphisms) have been analyzed and a representative sample of 85 breeds were placed into four clusters, each cluster having shared ancestors. Cluster 1 is thought to be the oldest, including African and Asian dogs. Cluster 2 is mastiff type dogs; cluster 3 is herding dogs, and cluster 4 modern hunting type dogs (mostly developed in Europe in the 1800s.)

  • Note: Relationships uncovered through genetics may not match "official" breed histories. The following breed lists are based on genetic research, not traditional beliefs about dog breeds.
