EXTERNAL STUDY This is a summary of an external study
This study found that only 6 or 7 locations within the dog genome account for roughly 80% of the difference in height and weight among dog breeds.

This study of dog genomes sought to identify the genetic differences among various dog breeds. Researchers found six or seven locations in the dog genome that account for about 80% of the differences in height and weight among dog breeds.

In this study, researchers genotyped more than 900 dogs and assessed almost 60 physical traits, finding that only a few genetic regions determine the basics of a dog’s appearance. Scientists believe that studying these genetic differences among dog breeds may develop further scientific understanding of human biomedical traits.

Behavioral Differences Among Breeds of Domestic Dogs (Canis lupus familiaris): Current Status of the Science

Though there is a tremendous amount of visible variation among dog breeds, all domestic dogs belong to the species Canis lupus familiaris. This study examines how much breed variation has an effect (or lack thereof) on behavioral traits, recognizing that many particular types of dogs have been bred for hundreds and sometimes thousands of years. The results show that the behavioral differences thought to exist among different breeds are more pronounced depending on the research methods used.
