Theories about K9 Dog Genetics

Over the years, many theories have emerged about how domestication of dogs took place. Some believed that dogs evolved from a jackal-like animal now extinct; others thought they descended from the Pariah dog roaming North Africa, the Middle East, and India. The most likely theory, now genetically proven, is that dogs came from the wolf.

The Role of K9 Dog Genetics Since the Split of Dog and Wolf

With the publication of the dog genome in 2003, scientists finally confirmed that dogs descended from wolves. Most recognised breeds today originated less than 150 years ago, though dogs and wolves split 15,000 to 40,000 years ago. However, only about 0.04% of the dog genome has evolved to date.

K9 Dog Genetics Groups

Genetic classification reveals two major dog breed groups: one genetically closer to wolves, spread across Africa, Asia, the Middle East, Siberia, and Alaska; and a second, larger group of “European origin” breeds. Despite physical differences, only minor genetic differences exist between them. Even after 150 years, genetic variation among European breeds remains minimal.

K9 Dog Genetics Groups Have Few Cognitive Differences

While dogs differ vastly in appearance, only a few genes determine their physical traits. Therefore, cognitive differences between breeds are minimal, challenging the belief that certain breeds are uniquely suited for specific tasks. This suggests a dog’s suitability often lies more in training and handling than in genetics alone.
