Scientists have decoded the complete genome of the domestic dog, a milestone announced Wednesday that provides a biological roadmap for unraveling human diseases and probing the mysterious bond ...

A study has allowed researchers to link dog behavior with specific genetic lineages. In the study, published in Cell, researchers claim that “selective breeding of domestic dogs has generated diverse ...

Man's best friend, in this case a male poodle, is genetically more similar to humans than is the mouse, a more commonly used laboratory animal, according to researchers who have completed the first ...

Finally, Fido has a proper family tree. Genetic researchers have assembled the most definitive evolutionary tree of dogs using gene sequences from 161 modern breeds. The map of dog breeds and how they ...

Mapping the relationships between different dog breeds is rough (get it?), but a team of scientists at the National Institutes of Health did just that using the DNA of 1,346 dogs from 161 breeds.
