I learned recently that dogs have been found to have mutations that are equivalent to a genetic mutation in humans that would make a person more sociable and less intelligent.
New research seems to show that dogs have mutations to equivalent genetic regions in humans where changes are known to trigger high sociability and somewhat reduced intelligence.

Evolution of the wolf
The evolution of the wolf occurred over a geologic time scale of 800 thousand years, transforming the first Middle Pleistocene wolf specimen that is recognized as being morphologically similar to "Canis lupus" into today's dog, dingo and gray wolf. Ecological factors including habitat type, climate, prey specialization and predatory competition has greatly influenced the wolf's genetic population structure and cranio-dental plasticity. Wolves went through a population bottleneck 20,000 years before present (YBP), which indicates that many wolf populations had gone extinct at a time that coincided with the Last Glacial Maximum and the expansion of modern humans worldwide with their technology for capturing large game.
Origin of the domestic dog
The origin of the domestic dog is not clear. The domestic dog is a member of the genus "Canis", which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The closest living relative of the dog is the extant gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated. The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago.
Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. Evolutionary processes give rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. Repeated formation of new species (speciation), change within species (anagenesis), and loss of species (extinction) throughout the evolutionary history of life on Earth are demonstrated by shared sets of morphological and biochemical traits, including shared DNA sequences. These shared traits are more similar among species that share a more recent common ancestor, and can be used to reconstruct a biological "tree of life" based on evolutionary relationships (phylogenetics), using both existing species and fossils.
Frameshift mutation
A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier in the sequence the deletion or insertion occurs, the more altered the protein. A frameshift mutation is not the same as a single-nucleotide polymorphism in which a nucleotide is replaced, rather than inserted or deleted.
Mutation
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA (such as may be caused by exposure to radiation or carcinogens), which then may undergo error-prone repair (especially microhomology-mediated end joining), or cause an error during other forms of repair, or else may cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements.
BRCA mutation
A "BRCA" mutation is a mutation in either of the "BRCA1" and "BRCA2" genes, which are tumour suppressor genes. Hundreds of different types of mutations in these genes have been identified, some of which have been determined to be harmful, while others have no proven impact. Harmful mutations in these genes may produce a hereditary breast-ovarian cancer syndrome in affected persons. Only 5-10% of breast cancer cases in women are attributed to "BRCA1" and "BRCA2" mutations (with "BRCA1" mutations being slightly more common than "BRCA2" mutations), but the impact on women with the gene mutation is more profound.
Cancer
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread to other parts of the body. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they may have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity, and excessive drinking of alcohol.

I read about that too.  I wonder why that is?

It's an interesting new discovery. But unfortunately the origin of the domestic dog still isn't clear.

Dingo
The dingo ("Canis lupus dingo" or "Canis dingo") is a type of feral dog native to Australia. The first British colonists to arrive in 1788 established a settlement at Port Jackson and recorded dingoes living there with indigenous Australians. Although the dingo exists in the wild, it associates with humans but has not been selectively bred similarly to other domesticated animals. It is a medium-sized canid that possesses a lean, hardy body designed for speed, agility and stamina. The dingo's three main coat colours are described as being either light ginger (or tan), black and tan, or creamy white.

Dog
The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of the genus "Canis" (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species.
Dingo (taxon)
The taxon dingo refers to the native dog found in Australia but may at times also refer to some similar dogs native to peninsular and island southeast Asia and neighboring regions, such as the New Guinea singing dog. The genetic evidence indicates that the "dingo" clade originated from East Asian domestic dogs and was introduced through the Southeast Asian archipelago into Australia, with a common ancestry between the Australian dingo and the New Guinea singing dog. In 1758, the taxonomist Linnaeus published in his "Systema Naturae" the taxonomic classification of species. "Canis" is a Latin word meaning dog, and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals.
Small Greek Domestic Dog
Kokoni () is the name used for the Greek small domestic dog breed. They are widely found in Greece, have traditionally been more common in urban areas and were a popular companion of Greeks for centuries. The name "Kokoni" probably derives from the word κοκόνα "kokona" which is another word for daughter in Modern Greek. In past times the daughter's life was mostly in and around the house, so the Kokoni dog was the "daughter's dog" or the "dog for the house", unlike the hunting dogs or the livestock guardian dogs. In some places in Greece the word Kokoni is used for any dog incapable of serious working duties (e.g.
Dog behavior
Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli. It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans and they are uniquely attuned to their behaviors. Behavioral scientists have uncovered a wide range of social-cognitive abilities in the domestic dog  The origin of the domestic dog ("Canis lupus familiaris" or "Canis familiaris") is not clear.

dp you think humans can be selectively bred like dogs?  Maybe thats why.
